The cross sections were measured over an energy range from 0.001 to 25 eV and are similar except in the region above similar to 3 eV where ''direct'' processes dominate. Here the H2D+ cross sections are approximately four times smaller than those for H-3(+). The two-body fraction for H2D+ + e --> H-2+D or HD+H shows much the same behavior as is found for H-3(+) + e --> H-2+H. At E-rel <0.1 eV, the two-body fraction is somewhat higher for H2D+, e.g., for H: at relative energy of 4 eV, the value is 0.65 as against similar to 0.9 for H2D+ at the same energy. An isotope effect in the two-body channel for H2D+ is observed giving a product ratio of HD/H-2 congruent to 2.5 over the entire range. Correcting for the statistical predominance of HD, we get HD/2H(2) = 1.20 +/- 0.05. RP Datz, S (reprint author), OAK RIDGE NATL LAB,DIV PHYS,POB 2008,OAK RIDGE,TN 37831, USA.

The newly developed soft-switching inverter employs an auxiliary switch and a resonant inductor per phase to produce a zero voltage across the main switch so that the main switch can turn on at the zero-voltage condition, Both the auxiliary switch and the resonant inductor are operating at a fractional duty, and thus are small in size as compared to the main inverter circuit components. Operation modes in a complete zero-voltage switching cycle for the single-phase soft-switching inverter are described in detail with graphical explanations. The circuit operation was first verified by a computer simulation and then tested with a 1-kW single-phase and a 100-kW three-phase inverters. Experimental results are presented to show the superior performance in efficiency improvement, EMI reduction, and dv/dt reduction of the proposed soft-switching inverters.

This design incorporates a frequency tripler that provides a 600 MHz output capability using a 200 MHz 3(rd) overtone resonator. This design has some advantages over equivalent SAW alternatives: lower power-consumption, superior aging characteristics, linear frequency pulling and low frequency versus temperature sensitivity. The VCO presented demonstrates > +/- 60 ppm pullability (0 to 7V control), tuning linearity better than +/- 5% with phase noise at 1 kHz < -110 dBc/Hz. This oscillator-tripler exploits the nonlinear characteristics of an emitter-coupled-pair differential amplifier to obtain a highperformance oscillator design.

Its energy range extends from 1 keV (for neutrons, thermal energies) to hundreds of TeV for muons and electrons/photons. The maximum energy for hadron showers is around 10-30 TeV. The fall range of sophisticated tools provided by the latest version of the FLUKA code must be exploited in order to cope with the extremely complex radiation fields expected around the planned LHC experiments. The statistics needed in order to calculate accurately attenuation factors of up to 11 orders of magnitude over the whole rone of interest - including the beam interaction region, the massive detector, the huge cavern, the shafts and an external skyshine region - can be achieved thanks to a variety of importance sampling techniques. The capability to describe accurately transport in magnetic fields (taking multiple Coulomb scattering into account) has been found critical for penetrating charged particles such as muons. The FLUKA neutron cross section library, including several elements at different temperatures, provides a unique possibility to account for the temperature dependence of neutron cross sections in the cryogenic materials commonly used in high energy particle calorimetry. Thin-mesh spatial binning, a special feature of FLUKA, has also been found extremely useful to provide dose and flux distributions in space, leading to a better understanding of radiation behaviour. As a significant example, calculations made for the ATLAS experiment are presented, including a description of the detector and surrounding hall with np to 800 geometry regions. Caps and inhomogeneities have been reproduced to a high level of detail to account for non uniform streaming. Cross sections for more than 50 different materials at liquid Argon, liquid Helium and room temperatures have been used. To increase computer speed and obtain good statistical accuracy, a full biasing strategy has been adopted depending on particle type, position and energy.

The preliminary upgrade plan for the new facility includes; 1) adding a superconducting booster for the tandem accelerator, 2) replacing the 1960-vintage, 60 MeV proton, 50 microamp ORIC with a modern 200 MeV proton, 200 microamp cyclotron, and 3) building a high power (238)U fission target to accept the 200 MeV proton beam. This report summarizes the results of a preliminary one-dimensional shielding analysis to determine the feasibility of such an upgrade with respect to existing shielding from the facility structure, and additional shielding requirements for the high-power 200 MeV proton, 200 microamp (238)U target-ion source.

The beam stop is composed of a graphite region to stop the electron pulses and a surrounding tungsten region to attenuate photons produced by electron transport in the graphite. Radiation-transport dose calculations were performed to set the dimensions of the graphite and tungsten regions. To reduce calculational effort, electron transport in the graphite was calculated separately from photon dose transport to worker locations. The source for photon dose transport was generated by tallying photons emerging from the graphite during electron transport. C1 Univ Calif Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

The NRC is currently involved in a rulemaking effort to establish residual contamination criteria for restricted or unrestricted release of facilities. The purpose of this study was to provide guidance to licensees for selection and proper use of portable survey instruments, and an understanding of the field conditions under which, and the extent to which, the capabilities of those instruments can be limited. Currently, the assessment of surface contamination is performed by converting the instrument response to surface activity using the total efficiency. This is not a problem provided that the calibration source exhibits characteristics similar to the surface contamination, i.e., radiation energy, backscatter effects, source geometry, self-absorption, etc. In practice this is seldom the case; more likely, instrument efficiencies are determined with a clean, stainless steel source, and are used to measure contamination on a dust-covered concrete or wood surface. By separating the total efficiency into instrument and source efficiency components, the surveyor has a greater ability to consider the actual characteristics of the surface contamination. The minimum detectable concentration (MDC) depends on factors that are both instrument- and source-related. Determining the surface activity level allows one to isolate the two components of total efficiency and to evaluate the effects of each component on the MDC. Data were obtained for parameters that affected the instrument efficiency (e.g., source-to-detector geometry, distance from the source), and for parameters that affected source efficiency (e.g., surface type and coverings, such as oil, paint, and dust). MDCs were calculated to provide a quantitative assessment of the particular field condition on detection sensitivity.

To help resolve this discrepancy, we have used a sensitive multisphere neutron spectrometer to measure the neutron spectrum at 5 distances from 300 m to nearly 2 km from the bare critical assembly (small unshielded fission reactor) at the U. S. Army Pulse Radiation Facility (APRF) for comparison with long-range transport calculations. The measured neutron spectra all have a similar shape, with slight hardening as distance increases beyond 715 m. There is general agreement between our measured neutron spectra and fluences, including thermal neutron fluences, and APRF neutron spectra and fluences calculated using methods similar to those used for the long-range transport part of recent Japanese survivor dosimetry calculations. We conclude that the Hiroshima neutron discrepancy is probably not primarily due to problems with the long-range transport calculations. We also note that the falloff of the thermal neutron fluence with distance we measured at APRF closely matches that for the thermal neutrons at Hiroshima determined from activation measurements. This suggests that many more nearly unmoderated fission neutrons (or at least neutrons above the oxygen cross section window at 2.35 MeV) escaped from the Hiroshima weapon than were assumed in the DS-86 model. If the Hiroshima survivors were exposed to significant numbers of fast neutrons, and not just to gamma rays, estimates of the health risks from exposure to all types of radiation would be affected.

The AP is determined by requiring: (a) the eigenvalue of the combined mesh sweep-AP iterations to vanish in the vicinity of the origin in Fourier space; and (b) the diagonal and off-diagonal elements of the preconditioner to satisfy a diffusion-like condition. The spectra of the resulting iterations for a wide range of problem parameters exhibit a spectral radius smaller than .25, that vanishes implying immediate convergence for very large computational cells. More importantly, unlike other unconditionally stable acceleration schemes, the AP is cell-centered and its spectral radius remains small when the cell aspect ratio approaches 0 or infinity. Testing of the AP and comparison of its rate of convergence to the standard Source Iterations (SI) for Burre's Suite of Test Problems (BSTeP) demonstrates its high efficiency in reducing the number of iterations required to achieve convergence, especially for optically thick cells where acceleration is most needed.

Since the primary design criterion for this effort was that the utility "see" the geometric model exactly as the radiation transport code does, ORIGAMI is designed to utilize the same "ray-tracing" package as the revised version of MASH. ORIGAMI incorporates the functionality of two previously developed graphical utilities, CGVIEW and ORGBUG, into a single consistent interface. C1 Oak Ridge Natl Lab, Oak Ridge, TN 37831 USA.

The CSS class library is based on the Constructive Solid Geometry approach, which allows constructing an arbitrary geometry in terms of boolean operations on finite closed primitive bodies. It allows one to build hierarchical, tree-like structures which contain elementary and composite bodies. The paper covers an internal structure of the engine and its use in the frame of the MARS code system. Implementation issues and optimization techniques are discussed. The geometry engine is tied with a visualization subsystem, which is based on the Open Graphics Language (OpenGL). The subsystem handles wire-framed and solid bodies, supports orthonormal or perspective projections, rotations and shifts, clipping by arbitrary planes, lighting with different light sources. The user interface based on the Tcl-Tk package is also described. C1 Fermi Natl Accelerator Lab, Batavia, IL 60510 USA.

The model incorporates reactor geometry, material compositions, and operating history data acquired from Yankee Atomic Electric Company. In addition to the base activation analysis, parametric studies were performed to determine the sensitivity of activation to specific parameters. The calculations for Yankee Rowe predict that the core baffle and the core support plates should be activated to levels above Class C limits. Parametric calculations show that the waste class of the core barrel may potentially be above Class C when uncertainties in material compositions are considered. These results are generally applicable to other PWRs with over ten EFPY of operating experience. C1 Battelle Mem Inst, Pacific NW Labs, Richland, WA 99352 USA.

However, a naive importance-weighted comb does not preserve the total particle weight. This nonpreservation is generally unimportant for neutron and photon transport. However, this nonpreservation can be very important in simulations of charged particles where the particles are generating the electric field through which they are being transported. From a,Monte Carlo standpoint, preserving the expected weight by a combing technique produces an unbiased result. However, there may be a serious degradation to the physics of the problem if total charge is not exactly conserved. This paper describes a combing method that preserves the total weight and hence the total charge. C1 Univ Calif Los Alamos Natl Lab, XTM, Los Alamos, NM 87544 USA.

This concept suggests the use of small, depleted-uranium silicate glass beads as a backfill material inside storage, transportation, and repository waste packages containing spent nuclear fuel. Use of this backfill material would substantially reduce external dose rates from a waste canister, allowing a reduction of the amount of external shielding required. This paper summarizes the results of scoping studies to estimate the dose reduction from the use of DUSCOBS in a conceptual canister design, and to determine what design modifications are required to offset the increased mass of the system, while simutaneously maintaining sufficient shielding to meet external dose rate limits.

This feature includes first and second order terms of the Taylor series expansion for response perturbations, related to cross-section data (i.e., density, composition, etc.). Perturbation and sensitivity analyses can benefit from this technique in that predicted changes in one or more tally responses may be obtained for multiple perturbations in a single run. The user interface is intuitive, yet flexible enough to allow for changes in a specific microscopic cross-section over a specified energy range. With this technique, a precise estimate of a small change in response is easily obtained, even when the standard deviation of the unperturbed tally is greater than the change. Furthermore, results presented in this report demonstrate that first and second order terms can offer acceptable accuracy, to within a few percent, for up to 20-30% changes in a response.

RASCAL was designed to be used by U.S. Nuclear Regulatory Commission (NRC) personnel who report to the site of a nuclear accident to conduct an independent evaluation of dose and consequence projections and personnel who conduct training and drills on emergency responses. It allows consideration of the dominant aspects of the source term, transport, dose, and consequences. RASCAL consists of three computational tools: ST-DOSE, FM-DOSE, and DECAY. ST-DOSE computes source term, atmospheric transport, and dose to man from accidental airborne releases of radionuclides. The source-term calculations are appropriate for accidents at U.S. power reactors. FM-DOSE computes doses from environmental concentrations of radionuclides in the air and on the ground. DECAY computes radiological decay and daughter ingrowth. RASCAL 2.1 is a DOS application that can be run under Windows 3.1 and 95. RASCAL has been the starting point for other accident consequence models, notably INTERRAS, an international version of RASCAL, and HASCAL, an expansion of RASCAL that will model radiological, biological, and chemical accidents.

Because cities and counties are large energy users, this project aims to inform out audience about opportunities to save energy and dollars by using energy efficiency measures and renewable energy technologies. The project presents actual success stories-with demonstrated energy or dollar savings-written for nontechnical decision makers in local governments. Sponsored by the U.S. Department of Energy, the C&C Project is a multifaceted campaign including 30 fact sheets, a resource guide, an order form, a file folder, an evaluation card, a press kit, an exhibit, a special insert in a national publication, and on-line publishing. Distribution of these materials was based on a detailed marketing plan. We developed this plan using information gathered from an informal poll of various organizations that serve city and county government officials. The response rate for the project has been almost 21%, a phenomenal response, (Typically, response rates of 3% to 5% are considered successful results for a direct-mail campaign.) Perhaps the most meaningful results are that nine respondents who returned evaluation cards have indicated that they are planning to initiate a new energy-efficiency project or improve an existing one. An actual change in behavior is the highest impact we could have hoped for. This paper describes the methodology of the project in more detail and presents summaries of some of the exciting local projects featured in C&C materials.

Some park facilities pay over 50 cent per KWH to generate eletricity at remote sites. Budget priorities, a shortage of funding and lack of technical energy expertise within the NPS have kept parks, recreation areas and monuments from aggressively undertaking energy efficiency and renewable energy projects. Recognizing the vast potential for cost-effective renewable energy and energy efficiency projects the Department of Energy's Denver Regional Support Office (DRSO) and the former Rocky Mountain Region of NPS drafted an interagency agreement formalizing a collaborative effort. This paper highlights a number of projects already underway involving a variety of partnerships among NPS and State Energy Offices, Weatherization Offices, Department of Energy (DOE) Labs, FEMP and other DOE programs. It also identifies potential projects which may interest solar businesses and energy service companies. RP Snyder, K (reprint author), NREL,DEPT ENERGY,2801 YOUNGFIELD ST,GOLDEN,CO 80401, USA.

The benefit of modeling these systems could be realized by decreasing the cost of reactor design by trial-and-error and in finding optimal reactor operating parameters. 2-D modeling of these systems have been performed using a continuum code to predict electron properties and the Direct Simulation Monte Carlo (DSMC) technique for simulating heavy particle transport; that is, both ion and neutral particles. This paper presents a detailed comparison of experimental data for an electronegative chlorine plasma to simulations results. Data comparisons for a pure chlorine plasma at 20-50 mtorr and 185-300 W for an inductively coupled source include: radial dependence of n(e), T-e, Cl-, Cl+ and ion and angular distribution functions. Emphasizing the comparison of model results with diagnostic data will establish the DSMC plasma model as a viable tool for accurately predicting low pressure, electronegative, plasma generation and transport.

The properties of lithium ions in silicon as well as their interactions with point defects are well known (2). Using lithium ion drifting, we have evidence which shows that silicon self-interstitials are injected at least 1.5 mm into the bulk during wet oxidation or POCl3 processes (similar to 100 min. at 950 degrees C) (3,4). Results obtained by modeling oxidation and POCl3 processes with SUPREM-IV using point defect default values are not consistent with our results. However, our results are compatible with SUPREM-IV simulations using more recently published point defect parameters.

The calculated lowest energy (310) grain boundary structure and electronic properties are consistent with previous TEM measurement and calculations. For the controversial (710) grain boundaries, our tight-binding calculations do not show any electronic energy levels in the band gap. This indicates that with every atom fully fourfold coordinated, the (710) grain boundary should be electrically inactive. Some high-energy metastable grain boundaries were found to be electrically active by the presence of the levels introduced in the band gap. Also, the vacancy concentration at the (310) GB was found to be enhanced by many orders of magnitude relative to bulk. The dangling bond states of the vacancies should be electrically active.

Tile simulations start with a molecular dynamics (MD) calculation of the primary slate of damage alter 10ps. The results are then coupled to a kinetic Monte Carlo (MC) simulation of bulk defect diffusion and clustering. Dose accumulation is achieved considering that at low temperatures the damage produced in the lattice is stable. After the desired dose is accumulated, the system is annealed at 800 degrees C for several seconds. The results provide information on the evolution for the damage microstructure over macroscopic length and time scales and affords direct comparison to experimental results. We discuss the database of inputs to the MC model and how it affects the diffusion process. RP delaRubia, TD (reprint author), LAWRENCE LIVERMORE NATL LAB,L-268,LIVERMORE,CA 94550, USA.

These devices produce molten particles with three to four times the impact velocity of conventional plasma sprays. With this increased range of particle velocity it is important to understand the relationship between sprayed particle size, velocity, temperature, trajectory, and spray pattern Measurements of particle velocity, temperature, and size along with spray pattern characteristics have been obtained for a plasma spray system operating at 110 kW. The plasma and particle now fields were also simulated with a pseudo 3-D model. The model assumes that the gas flow is axi-symmetric while the particles are treated in a fully 3-D manner. The particle behavior is modeled by a stochastic discrete-particle model which includes turbulent dispersion. Because the flowfield has a high swirl number, it was found that the injection geometry plays a particularly important role in determining particle trajectory, heating, and acceleration. In spite of the complexity of the system, i.e., supersonic plasma velocity with a high swirl component, the simulation produced reasonably accurate mean velocities, temperatures, and particle trajectories although the agreement between the calculated and measured particle velocity, temperature, and size distributions indicate that not all aspects are adequately modeled.

It was shown that lifting of Pt atoms of the surface layer occurs, substantiating the long-standing hypothesis of a place-exchange mechanism for solution/metal interface oxidation. It was also shown that, for a charge transfer of less than or similar to 1.7 e(-)/Pt atom, the initially flat surface structure could be recovered by electrochemical reduction. In contrast, the surface was irreversibly roughened for amounts of charge transfer exceeding similar to 1.7 e(-)/Pt, but the roughening involved only the atoms in the top layer of the original flat surface. A detailed mechanism is proposed for the place-exchange mechanism and the subsequent roughening of the electrode surface.

The aim was to investigate the effect of particle size on the electrocatalysis by Pt in acidic medium to better understand its role in determining the activity towards oxygen reduction as well as methanol oxidation. The results clearly show that below 50 Angstrom Pt surface is very susceptible to OH adsorption and forms stronger H bonds. There is also evidence of changes in morphology during potential transitions from hydrogen region to the double layer as evidenced by sharp changes in the coordination number. Such perturbations are reduced drastically above 50 Angstrom. The results for br situ methanol oxidation clearly show the unfavorable effect of oxygenated species on smaller particles (<50 Angstrom). This investigation therefore provides direct spectroscopic evidence of previously reported suggestions of this effect and the correlation of oxygenated species with particle size.

The pressure-induced phase can be achieved by compression to similar to 5kbar at room temperature. If cooled this phase can be retained below similar to 200K upon release of the pressure. The structure is orthorhombic as previously reported (but may differ in its detailed crystal structure) with lattice constants near 80K and ambient pressure of a = 9.385 Angstrom b = 10.06 Angstrom and c = 14.36 Angstrom. The corresponding linear compressibilities are 0.0004, 0.0014 and 0.0017 kbar(-1), respectively. Identical pressure temperature cycling results in a superconductor with an unexpectedly low pressure dependence for T-c while in this phase.

Here we present evidence that SWNTs are selectively opened by oxidation with H2O resulting in CO2 production and hydrogen termination of the tube ends. Temperature programmed desorption (TPD) measurements revealed significant H-2 adsorption on open 12 Angstrom diameter SWNTs at near ambient temperatures. The data suggest that adsorbed H-2 is stabilized within the internal cavities of carbon nanotubes by nanocapillary forces. Optimization of methods for producing SWNTs might allow these unique materials to be utilized far large-scale storage and purification of gases. Towards this goal, we employed both transmission electron microscopy (TEM) and H-2 TPD to optimize single-wall nanotube content as a function of rod translation rate during synthesis.

Cobalt-doped graphite targets were fabricated from mechanical mixtures of cobalt and graphite, and from graphite powders doped by infiltration of Co-2(CO)(8).

NiAl exhibited improved passivity compared to Ni at a pH of 2, and improved passivity compared to Al at pH 12.5. Water oxidation and reduction were enhanced on NiAl compared to Al at each pH, suggesting presence of a more conductive oxide film compared to Al/Al2O3. Al2O3 was preferentially formed (>50 atomic % of all oxidized Ni and Al species) within the oxide formed anodically at each pH as well as within the native, air-formed oxide. Moreover, the outer surface layer of the anodic oxide formed at pH 2 was further enriched in Al+3, e.g. consisted of almost 70% Al+3 relative to Ni+2, In comparison, the oxide surface layer incorporated >50%, oxidized Ni+2 species after growth at pH 7 and 12.5. Therefore, Al2O3 formation is favored, but not exclusive, during electrochemical passivation. In contrast, little or no Ni+2 (as NiO or NIAl2O4) has been reported after high temperature oxidation of NiAl: Moreover, the composition of the surface oxide formed in aqueous solutions is governed by the specific thermodynamic solubility and/or kinetic dissolution rates of the component metal oxides at the oxide/solution interface.

With increased pH the potential of the reduction arrests decreased and the charge associated with the arrest increased. A dependence of -60 mV/pH was observed except between pH 7.5 and 8.5 where the slope approximated -180 mV/pH. Above pH 7.5 the slope was consistent with the thermodynamic predicted slope of -180 mV/pH expected from reductive dissolution of ferric oxide forming soluble ferrous ions. At higher pH values, a slope of -60 mV/pH has been accounted for by oxide reduction to form a solid lower valent oxide.

The passive film that forms in pH 8.2 sodium acetate (0.1 M) at +0.4 V gives an edge similar to the high potential passive film formed in berate buffer, but dissolution occurs prior to passivation.

The oxide film on copper at -0.05 V vs SCE in 0.1 M NaOH solution has been identified as Cu2O. In the passive region at 0.3 V, CuO and Cu(OH)(2) appear to be present on the surface. In dilute solution of KOCN in perchlorate, vibrational bands have been observed that could be attributed to a few monolayers of Cu(OCN)(2). Results of studies on platinum in 0.5 M HClO4 suggest the existence of a hydroxylated species prior to complete oxidation of the surface.

Hence, in many cases, there is a gap in our detection capability between the lower limit of GPR and the upper limit of traditional electromagnetics (EM). Bridging this gap is essential to the characterization of buried waste, contaminant plumes, and other environmental and hydrogeological targets located in the shallow subsurface. The Very Early Time Electromagnetic (VETEM) system is designed to ascertain the conductivity and dielectric properties of the shallow subsurface in conductive terrain (Pellerin et al.; 1994, 1995). Hence, the one-dimensional (1-D) and three-dimensional (3-D) numerical modeling algorithms, developed in the first year of the project, contain the full solution to the EM problem including both displacement and conduction currents. The VETEM system fills a gap between EM and GPR, but all three methods are necessary to successfully image the shallow subsurface. The VETEM participants recognize that other electromagnetic instruments and techniques developed in industry, academia and other research institutions for near-surface investigations have been developed since the baseline study was established for the VETEM project (Mac Lean; 1992, 1993). Many of these new instruments lack the interpretational software necessary for high-resolution 3-D imaging of the subsurface, but directly complement the VETEM instrumentation and can benefit greatly from application of the software developed in the VETEM project. Therefore, to achieve the goal of fully 3-D subsurface imaging, the VETEM project is hosting the Electromagnetic Integrated Demonstration (EMID) at the Idaho National Engineering Laboratory's Cold Test Pit (INEL's CTP). Over a dozen EM systems will acquire data over the same survey area for interpretation in conjunction with the VETEM team. To interpret the EMID data, the VETEM participants have been developing forward modeling software, instrumentation, and interpretational software. In addition to interpretation of field data, the forward modeling algorithms are being used in physical analysis of the problem and in the systems analysis devoted to instrument design. The prototype time-domain instrument employs a magnetic dipole transmitter and receiver and operates from 10 nano-second to a micro-second. The USGS high frequency sounder (HFS), which served as the VETEM proof-of-concept, uses the same antenna geometry as the time-domain instrument and acquires data from 30 kHz to 30 MHz. The first VETEM survey was recently conducted at the INEL's CTP as a part of the EMID. The electromagnetic migration technique is being investigated for interpretation the VETEM data. Multi-dimensional inversion and pattern recognition techniques are also available and will be used on complementary datasets acquired in the EMID.

At Hill Air Force Base in Utah, a free-product DNAPL plume (consisting predominantly of TCE) is pooled in water-wet soil on a thick clay aquitard. Groundwater pumping at Operable Unit 2 (OU 2) began in 1994; to date, nearly 30,000 gallons of DNAPL have been recovered from the site. From September, 1994 through September, 1995, changes in the basin during DNAPL pumping were monitored using an integrated geophysical system. Fiber optic sensors and neutron logs verify the presence of DNAPL in the vicinity of three boreholes which form a cross section from the perimeter of the basin to its center. Cross borehole electrical resistance tomography (ERT) images the changes in formation electrical properties due to the removal of DNAPL, extending the understanding of DNAPL removal between the boreholes. During pumping, electrical resistivities decreased; we suggest that these decreases are directly caused by the reduction in DNAPL. During ground water pumping, water with relatively low resistivity replaces some of the DNAPL pockets as the highly insulating DNAPL is removed. The results suggest that, as DNAPL is pumped from a nearby well, product slowly drains along the top of an aquitard and into the pump well, where it collects.

One hundred ninety liters of PCE were released at a rate of 2 liters per hour from a point 0.5 m below ground surface. The spill was conducted within a double walled tank where saturated layers of sand, bentonite and a sand/bentonite mixture were installed. Complex electrical resistance measurements were performed from 4 vertical electrode arrays, each with 10 electrodes spaced between 3 m and 0.5 m depth. Data were taken before the release, several times during, and then after the PCE was released. Magnitude and phase were measured at 1 and 64 Hz. Data from before the release were compared with those during the release for the purpose of imaging the changes in conductivity resulting from the plume. Conductivity difference tomographs showed a decrease in electrical conductivity as the DNAPL penetrated the soil. A pancake-shaped anomaly developed on the top of a bentonite layer at 2 m depth. The anomaly grew in magnitude and extent during the release and borehole television surveys data confirmed the anomaly to be free-product PCE whose downward migration was stopped by the low permeability clay. The tomographs clearly delineated the plume as a resistive anomaly. images showing phase changes caused by the spill are also presented. The phase changes at 64 Hz suggest that the DNAPL spill increased the induced polarization (IF) effect of the clay layers.

This paper provides a summary of the field experiments performed under a 15 m diameter steel tank mockup located at the Hanford Reservation, Washington. Two different leak events were created. About 3800 liters of saline solution were first released along a portion of the tank's edge and another 1900 liters were later released near the tank's center. The release rate averaged about 26 liters/hour for the leak on the tank's side and about 3.0 liters/hour for the center leak. Two and three dimensional tomographs were calculated using data collected before, during and after each spill. The tomographs show that, as the solution penetrated the soil, readily detectable resistivity decreases appeared where the associated plume was expected. The results indicate that the plume associated with these releases could be reliably detected after approximately 190 liters were released. Results are also shown where the metal tank is used as a large electrode. RP Ramirez, A (reprint author), LAWRENCE LIVERMORE NATL LAB,LIVERMORE,CA 94550, USA.

Our findings, based on electromagnetic and magnetic data, were incorporated in the federally mandated Environmental Assessment Statement (EAS), and in general supported claims that this land was never used as a hazardous waste disposal site. We estimated the amount of iron required to produce each anomaly using a simple dipole model. All anomalies with equivalent sources greater than approximately 1000 kg of iron were checked in the field, and the source of all but one identified as either a bridge, reinforced concrete debris, or a similarly benign object. Additionally, some smaller anomalies (equivalent sources of roughly 500 kg) have been checked; thus far, these also have innocuous sources. Airborne video proved invaluable in identifying logging equipment as the source of some of these anomalies. Geologic noise may account for some of the remaining anomalies. Naturally occurring accumulations of magnetic minerals in the soil on the ORR have been shown to produce anomalies which, at a sensor height of 30 m, are comparable to the anomaly produced by about 500 kg of iron. By comparison, the electronic noise of the magnetic gradiometer, 0.01-0.02 nT/m, is equivalent to only about 50-100 kg of iron at a 30 m sensor height. The electromagnetic data, combined with field mapping of karst structures, provided evidence of a northeast-southwest striking conduit spanning the parcel. The possible existence of a karst conduit led the EAS authors to conclude that this is a ''sensitive hydrologic setting.'' We conclude that aerial geophysics is an extremely cost-effective, and efficient technique for screening large tracts of land for environmental characterization.

A dig-face characterization system consists of onsite hardware for collecting detailed information on the changing chemical, radiological, and physical conditions in the subsurface during the entire course of a hazardous site excavation. The dig-face characterization concept originated at the Idaho National Engineering Laboratory and has been under development there since 1992. During August 1995, a prototype dig-face system was taken to Mound Laboratory, Ohio, for a first attempt at monitoring a hazardous excavation. Mound Area 7 was the site of historical disposals of Th-232, Ac-227, and assorted debris. The dig-face characterization system was used to monitor a 20-ft x 20-ft x 5-ft-deep excavation aimed at removing Ac-227 contaminated soils. Radiological, geophysical, and topographic sensors were scanned across the excavation dig-face at four successive depths as soil was removed in 1-ft to 2-ft lifts. The geophysical and topographic sensors located metallic debris and mapped the dig-face topography in great detail as the excavation advanced. The radiation sensors produced high-fidelity images showing the location of radioactive contaminants and clearly identified and delineated separate Th-232 and Ac-227 plumes. By combining the radiation data from all four levels, a three-dimensional image of the contamination plumes was developed. The radiation sensor data indicated that only a small portion of the excavated soil volume was contaminated. The spatial information produced by the dig-face system was used to direct the excavation activities into the area containing the(227)Ac and to evaluate options for handling the separate Th-232 plume.

This study was undertaken to aid in the assessment of the amount of remediation needed to reclaim a wetland area. An integrated analysis of electromagnetic, magnetic and ground-penetrating RADAR (GPR) measurements over a 25-acre site, provided the information necessary to define waste disposal events. These events are observed on a sequence of aerial photos taken between 1940 and 1993. The former southwestern embayment of the lake, filled in during the original construction of the base, has been clearly defined. Two burn cages and their surrounding debris have been delineated. The areal extent of another waste site has been defined along the northern shoreline. Depth estimates determined from EM-61 analysis, and depths to original lake bottom, derived from GPR, have yielded volumetric estimates of the amount of material that would need removal if excavation is required. Magnetic and electromagnetic data have pin-pointed the locations of mounds, observed from historical air photos. Except for these areas along the northwestern shore, there is no evidence of waste disposal along the shoreline or within the present-day lake margins. The ability to date the anomalous regions is significant, in that different production demands upon TCAAP, during the time periods of WWII, The Korean War, and The Vietnam Conflict, have resulted in different types of waste. The ability to categorize areas with distinct time periods of operation and waste disposal can greatly aid the environmental cleanup effort with regard to the type of contaminants that might be expected at these poorly documented disposal sites. .

There is great interest in using fiber optics to improve interconnect communication beyond that attainable using electronic technology. Several groups have considered WDM, star-coupled optical interconnects. In this paper, we propose a fiber optic transceiver to provide low latency, high bandwidth channels for such interconnects using a robust multimode fiber technology. We use instruction-level simulation to quantify the bandwidth, latency, and concurrency required for such interconnects to scale to 256 nodes, each operating at 1 GFLOPS performance. We show that performance scales to approximate to 100 GFLOPS for scientific application kernels using a small number of wavelengths (8 to 32), only one wavelength received per node, and achievable optoelectronic bandwidth and latency.

The only gas-phase process is complex formation, which can compete with deposition. The surface mechanism postulates the stepwise elimination of Cl and H atoms from TiCl4 and NH3, respectively, to form solid TiN and gaseous HCl. The mechanism also accounts for the change in oxidation state of Ti by allowing for liberation of N-2. Provided that the surface composition is at steady state, the stoichiometry of the overall reaction is reproduced exactly.

A simple one-step surface reaction is used to model deposition of gallium on the rotating surface. Partitioning of the inlet flow into separate gas streams of different species can lead to nonuniform deposition on the growth surface. The nonuniformity is caused by incomplete radial diffusion of gas species; depending on reactor temperature and pressure it can be worsened by large buoyant flow instabilities. The nonuniformity is relatively insensitive to tie magnitude of the specified sticking coefficient. RP Winters, WS (reprint author), SANDIA NATL LABS,LIVERMORE,CA 94551, USA.

Using the simulation results, a correlation for use in design has been developed based on laminar jet theory. A correlation is presented in which the value of the velocity variation is explicitly shown to depend on the geometry of the plenum and showerhead and on the mass flow The correlation for the root mean square (RMS) velocity is good to 3% over a wide range of geometries and flow rates.

However, the film quality onto ZnS was not satisfactory because of a high amount: of residual porosity, especially at the substrate/coating interface, an indication of much slower nucleation than growth. The use of a SrS layer on top of the ZnS improved the nucleation and greatly reduced the porosity in the coating. The crystallinity of the CaGa2S4 400 peak was also increased hy a factor of ten when a layer of SrS was used. Further, the FWHM of the 400 peaks between the two substrates was not significantly different, indicating that the crystallite size and strain was approximately me same. The B-40, was increased by a factor of two, from 1.84 cd/m(2) for ZnS to 3.67 cd/m(2) for SrS. While this increase is an improvement in the performance of the films, it was not the older of magnitude increase expected based on the crystallinity. As the Ce content is optimized in the films deposited onto SrS, the EL brightness is expected to increase. RP Moss, TS (reprint author), LOS ALAMOS NATL LAB,MAIL STOP E549,LOS ALAMOS,NM 87545, USA.

Films have been grown up to a thickness of 2500 Angstrom. The growth rate of the SiC film is not limited by the surface reaction rate of fullerene with silicon at these temperatures, rather by the arrival rate of the reactants Si (by diffusion from substrate or from gas phase) or fullerene. This results in rapid film growth. Films have been characterized by low energy electron diffraction, ultraviolet photoelectron spectroscopy and Auger electron spectroscopy. Stoichiometric, epitaxial SiC films are grown. Supply of silicon to the growing SiC surface via sublimation greatly reduces the tendency for silicon diffusion to form voids at the Si/SiC interface.

Crack deflection and fiber pullout are also necessary components of the mechanical behavior of composites. Screening interface materials and determining their optimum characteristics is a lengthy and expensive procedure if standard chemical vapor infiltration composite processing is used. A procedure for fabricating minicomposites was developed to address this problem. Minicomposites require very little material and much less labor than is necessary to produce a standard composite. Also, the mechanical property measurements made on minicomposites target the behavior of the interface coatings and their effect on the properties of the composite. Tensile testing of minicomposites was used to optimize the matrix infiltration process and will be utilized in the future to study the mechanical behavior of new materials systems, and specifically, new interface coating materials.

This was accomplished using GCMS (gas chromatography-mass spectroscopy) and FTIR (Fourier transform infrared spectroscopy) to examine how TEOS reaction rates are influenced by factors critical to the heterogeneous reaction. This included determining the TEOS pressure dependence, testing if reaction by-products inhibit TEOS decomposition, evaluating functional groups on the SiO2 surface as potential reaction sites, and establishing the functional group coverage dependencies. Our results show that TEOS decomposition rates are first-order in TEOS pressure and independent of the surface reaction by-products and the relative coverages of siloxane bridges (Si-O-Si) and hydroxyls on SiO2. These conclusions suggest that a precise knowledge of functional group coverages on SiO2 is not essential for modeling thermal TEOS decomposition rates at 1000K. In the absence of gas-phase reactions, growth rates should be directly proportional to TEOS pressure. Therefore, it is likely that non-uniform SiO2 depositions observed in thermal TEOS CVD are due to depletion of TEOS in the gas-phase and/or thermal gradients on the surface.

Tungsten (W) and tungsten silicide (WSix) can be utilized in a self-aligned gate process as an ion implantation mask during the formation of source and drain regions for metal-semiconductor FETs (MESFETs). The gate etch must be highly anisotropic to accurately define the implant region. In this paper we report the fabrication of sub-0.5 mu m W/WSix bilayer gates using electron beam lithography and dry etch techniques. Reactive ion etching (RIE) and high-density electron cyclotron resonance (ECR) etch processes are compared for W and WSix etch rates and etch profiles.

First, a sub-micron area post structure descending from a metallic airbridge allows gating of regions as small as 0.1 mu m in diameter. This has enabled the study of such quantum phenomena as coupling of parallel quantum point contacts, and electron focusing around a tunable quantum antidot. We also describe two new techniques for backgating multiquantum well structures with submicron lateral resolution. These techniques enable separate ohmic contacts to individual quantum wells spaced as closely as 100 Angstrom, and thus allow the fabrication of novel quantum tunneling devices. The first technique uses regrowth over a patterned ion-implanted substrate. The second involves a novel epoxy-bond-and-stop-etch (EBASE) processing scheme, whereby the original substrate is etched away and the backside then patterned using conventional methods.

Both Ga-and Al-based materials retain smooth, stoichiometric surfaces even at 1000W, but the rates are still much slower than for Cl-2 plasma chemistries.

Big sagebrush was planted to aid in the recovery of sage grouse on the Reserve. A Geographic Information System screening process was used to optimize planting site selection and reduce the time required in the field to identify suitable planting sites. Criteria for selection of planting sites were geographically defined and converted into a series of map layers. Overlapping map regions meeting all criteria became the basis for field reviews leading to final planting site selection. The process of using a GIS to screen for potential planting locations was effective in optimizing plant site selection and greatly decreased the time required to locate suitable planting sites.

Electrons can be extracted from any of the five recirculation passes and beam can be simultaneously delivered to the three experimental halls. As the commissioning stage nears completion, the accelerator is becoming a fully operational machine. Experiments in Hall C have been underway since November 1995 with beam powers of over 300 kW at various energies. Hall A has received beam for spectrometer commissioning, white Hall B is expected to receive its first beam in the fall of 1996. Accelerator availability of greater than 70% during physics runs and excellent beam quality have contributed to making Jefferson Lab a world class laboratory for accelerator-based electromagnetic nuclear physics. With the highperformance of the superconducting RF cavities, machine upgrades to 6 GeV, and eventually 8 to 10 GeV are now in the planning stages. Operational and commissioning details concerning all aspects of the machine will be discussed.

Since the majority of the technical risk of a high-current cw (continuous-wave, 100% DF) accelerator resides in the low-energy section, Los Alamos is building a 20 MeV duplicate of the accelerator front end to confirm design codes, beam performance, and demonstrate operational reliability. We report on design details of this low-energy demonstration accelerator (LEDA) and discuss the integrated design of the full accelerator for the APT plant. LEDA's proton injector is under test and has produced more than 130 mA at 75 keV. Fabrication is proceeding on a 6.7-MeV, 8-meter-long RFQ, and detailed design is underway on coupled-cavity drift-tube linac (CCDTL) structures. In addition, detailed design and technology experiments are underway on medium-beta superconducting cavities to assess the feasibility of replacing the conventional (room-temperature copper) high-energy linac with a linac made of niobium superconducting RF cavities.

To generate high quality, intense beams of accelerated radionuclides via the ''isotope separator on-line'' (ISOL) method requires two major accelerator components: a high power (100 kW) driver device to produce radionuclides in a production target/ion source complex, and a secondary beam accelerator to produce beams of radioactive ions up to energies on the order of 10 MeV per nucleon over a broad mass range. In reviewing the technological challenges of such a facility, several types of modern linear accelerators appear well suited. This paper reviews the properties of the linacs currently under construction and those proposed for future facilities for use either as the driver device or the radioactive beam postaccelerator. Other choices of accelerators, such as cyclotrons, for either the driver or secondary beam devices of a radioactive beam complex will also be compared. Issues to be addressed for the production accelerator include the choice of ion beam types to be used for cost-effective production of radionuclides. For the post-accelerator the choice of ion source technology is critical and dictates the charge-to-mass requirements at the injection stage.

The second source produces much lower intensity 'witness' pulses which are used to probe the fields produced by the drive.

A sine-wave chopper has been used for this purpose up to now. Such a device can have a significant detrimental effect on the longitudinal and transverse beam emittance of heavy-ion beams which can be sufficiently severe to limit the overall beam quality from the ATLAS accelerator. A study of the optimum chopper configuration and chopper type was undertaken as part of a new ion source project for ATLAS. A transmission-line chopper and a two-harmonic chopper were investigated as alternatives to the conventional sine-wave chopper.

Numerical studies have shown that a transverse (normalized) acceptance of 0.25 x mm-mrad can be achieved while maintaining a longitudinal emittance as small as a few keV-nsec. A novel feature is the use of drift-tubes at the entrance and exit of the RFQ which make use of the voltage offsets intrinsic to the split-coaxial structure to increase the voltage gain by about 30%. A half-scale model of the RFQ has been built and tested. The model, with no provision for cooling, was not operable cw but was pulsed to vane-vane voltages as high as 59 kV for periods of several milliseconds. The achieved level, Limited by arcing in an rf feedthrough and so not a fundamental limit for the structure, corresponds to 1.2 times the (frequency and gap dependent) Kilpatrick limit. Assuming the model results scale, a 2 meter long 12 MHz RFQ, with 8 mm minimum aperture radius, will operate at 100 kV intervane voltage with an RF input of slightly less than 25 kW.

The 1497 MHz continuous electron beam is composed of three interlaced variable-intensity 499 MHz beams that can be independently directed from any of the five passes to any of the three experimental halls. Beam extraction is made possible by a system of nine warm sub-harmonic separator cavities capable of delivering a 100 mu rad kick to any pass at a maximum machine energy of 6 GeV. Each separator cavity is a half-wavelength, two cell design with a high transverse shunt impedance and a small transverse dimension. The cavities are powered by 1 kW solid state amplifiers operating at 499 MHz. Cavity phase and gradient control are provided through a modified version of the same control module used for the CEBAF SRF cavity controls. The system has recently been tested while delivering beam to Hall C. In this paper we present a description of the RF separator system and recent test results with beam.

Unexpectedly large transverse wakefield kicks were observed from the collimators in this region during 1995. Upon inspection, it was found that the 20 mu m gold plating had melted and formed a line of spherules along the beam path. To refurbish the collimators, an improved design was required. The challenging task was to fmd a surface material with better conductivity than the titanium core to reduce resistive wakefields. The material must also be able to sustain the mechanical stress and heating from beam losses without damage. Vanadium was first chosen for ease of coating, but later TiN was used because it is more chemically inert. Recent beam tests measured expected values for geometric wakefield kicks, but the resistive wall wakefield kicks were four times larger than calculated.

Long-range transverse wakefields from the leading bunch were found to cause up to a factor of three increase in beam jitter for the trailing bunches. Incoming jitter is efficiently damped by BNS damping, but excitations in the middle of the linac from sources such as long-range wakefields can grow in amplitude. To measure the wake function, the time difference between the positron and electron bunches was changed determining the frequency and strength of the dominant mode contributing to the dipole wakefield. By splitting the horizontal and vertical phase advance, or 'tune', of the magnetic lattice, it was possible to decrease the resonant excitation from these wakefields and thereby reduce the jitter of the electron beam by a factor of two.

A strong focusing lattice combined with BNS damping controls the amplitude of oscillations which otherwise would grow exponentially. Measurements of oscillation amplitude along the linac show beam motion that is up to six times larger than that expected from injection jitter. A search for possible sources of jitter within the linac uncovered some problems such as structure jitter at 8 to 12 Hz, pump vibrations at 59 Hz and 1 Hz aliasing by the feedback systems. These account for only a small fraction of the observed jitter which is dominantly white noise. No source has yet been fully identified but possible candidates are dark current in the linac structures (not confirmed by experiment) or subtle correlations in injection jitter. An example would be a correlated x-z jitter with no net offset visible on the beam position monitors at injection. Such a correlation would cause jitter growth along the linac as wakefields from the head of the bunch deflect the core and tail of the bunch. Estimates of the magnitude of this effect and some possible sources are discussed in this paper. RP Decker, FJ (reprint author), STANFORD LINEAR ACCELERATOR CTR,STANFORD,CA 94309, USA.

Hence, the two beams are focused to the same correlation. However, matching to a DTL. requires correlation of the opposite sign. The Brown-Servranckx [1] quarter-wave (lambda/4) matching transformer system, which requires four quadrupoles, provides a method to simultaneously match H+ and H- beams between an RFQ and a DTL. The method requires the use of a special RFQ section to obtain the Twiss parameter conditions beta(x)=beta(y) and alpha(x)=alpha(y)=0 at the exit of the RFQ [2]. This matching between the RFQ and DTL is described below. RP Wadlinger, EA (reprint author), LOS ALAMOS NATL LAB,ACCELERATOR OPERAT & TECHNOL DIV,POB 1663,LOS ALAMOS,NM 87545, USA.

Rf power, generated when a bunched beam loses energy to an rf field when traversing an electric field that opposes the particle's motion, is used to drive a separate (or the same) cavity to either focus or deflect the beam. The deflected beam can be stopped by an aperture or directed to a different area of a target depending on beam current. The beam-generated rf power can drive a radio-frequency quadrupole that can change the focusing properties of a beam channel as a function of beam current (space-charge-force compensation or modifying the beam distribution on a target). An rf deflector can offset a beam to a downstream sextupole, effectively producing a position-dependent quadrupole field. The combination of rf deflector plus sextupole will produce a beam current dependent quadrupole-focusing force. A static quadrupole magnet plus another rf deflector can place the beam back on the optic axis. This paper describes the concept, derives the appropriate equations for system analysis, and gives examples. A variation on this theme is to use the wake field generated in an rf cavity to cause growth in the beam emittance. The beam current would then be apertured by emittance defining slits.

Two examples are fast high density explosive experiments and material science using neutron scattering. Flash x-rays are needed for imaging high density metal compression experiments. The short (50-75ns) pulse-burst capabilities of the induction linac are well suited to this. Because high x-rays doses are necessary to image the experiment and characterize density variations the multi-kiloampere capabilities of induction machines are attractive. Short neutron pulses from proton induced spallation can provide excellent energy and time resolution in material studies using neutron scattering. The induction Linac simplifies spallation sources by transporting and accelerating the total beam current necessary (amperes of H+) in a single beam with no storage. Concepts for both applications are discussed with emphasis on technical risks and costs. RP Rutkowski, HL (reprint author), UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,BERKELEY,CA 94720, USA.

Moreover, mechanical steering by moving the entire LEBT with a special low-friction vacuum joint was also demonstrated. The LEBT was tested with unanalyzed protons from an RF-driven bucket source by measuring the beam directly and by measuring the transmission through a subsequent RFQ as a function of LEBT electrode parameters. Agreement between calculated LEBT beam characteristics and actual measured values is excellent. This LEBT offers fully unneutralized beam transport with steering and two-knob control of exit Twiss parameters, and can be applied to negative hydrogen as well as proton beams.

This new design integrates the traveling-wave beam deflector, an electrostatic quadrupole, and clearing electrodes into a single compact structure. The four-electrode device performs ion clearing and linear focusing in the quadrupole (or transmit) mode, and also serves as a fast kicker in the deflecting mode. A QSWD operates with a constantly sustained electric field that sweeps off the ions and electrons produced by beam-gas scattering. Thus, a chopper using the QSWD can avoid beam neutralization with consequent emittance growth due to the beam-plasma interaction. We shall present the theoretical studies and the design considerations of the quadrupole deflector. A conceptual design of the chopper for a proposed Long Pulse Spallation Neutron Source (LPSS) at Los Alamos will be given as an example.

Foremost is the feedback control of the accelerating fields within the cavity in order to maintain field stability within +/-1% amplitude and 1 degrees phase. The feedback control system requires a phase-stable RF reference subsystem signal to correctly phase each cavity. Also, instead of a single klystron RF source for individual accelerating cavities, multiple klystrons will drive a string of resonantly coupled cavities, based on input from a single LLRF feedback control system. To achieve maximum source efficiency, we will be employing single fast feedback controls around individual klystrons such that the gain and phase characteristics of each will be ''identical.'' In addition, the resonance condition of the cavities is monitored and maintained. To quickly respond to RF shutdowns, and hence rapid accelerating cavity cool-down, due to RF fault conditions, drive frequency agility in the main feedback control subsystem will also be incorporated. Top level block diagrams will be presented and described as they will first be developed and demonstrated on the Low Energy Demonstrator Accelerator (LEDA).

We plan to use a 500 keV, 5 kA, 6-cm-dia annular electron beam to excite a TM(02) mode Raman FEM amplifier in a corrugated cylindrical waveguide. The annular beam will run close to the interaction device walls to reduce the power density in the fields, and to greatly reduce the kinetic energy loss caused by beam potential depression associated with the space charge which is a significant advantage in comparison with conventional solid beam microwave tubes at the same beam current. A key advantage of the annular beam is that the reduced plasma wave number can be tuned to achieve phase stability for an arbitrary correlation of interaction strength with beam velocity. It should be noted that this technique for improving phase stability of an FEM is not possible with a solid beam klyston. The annular beam FEM provides the opportunity to extend the output power of sources in the 17 GHz regime by well over an order of magnitude with enhanced phase stability.

Two single-cell RF bunchers in the low energy beam transport (LEBT) prepare the initially unbunched beam for DTL capture. The transverse distribution at the entrance to the DTL is set with four quadrupoles in the 1.26m between the last transverse emittance measuring station and the DTL entrance. Previous matching algorithms used TRACE and TRACE 3-D to determine these quadrupole strengths. PARMILA simulations show this procedure produces non-zero mismatch and additional emittance growth through the DTL for high current beams. Because of strong space-charge forces and a rapidly forming longitudinal bunch, simple envelope calculations do not model the beam evolution in the LEBT well. A PARMILA model of this region was combined with an iterative search routine to set the LEBT quadrupole strengths to achieve a better transverse match into the DTL.

Previously it was sufficient to perform simulations with of order 10000 particles, but recently the need to perform high resolution halo studies for next-generation, high intensity linacs has made it necessary to perform simulations with of order 100 million particles. With the advent of massively parallel computers such simulations are now within reach. Parallel computers already make it possible, for example, to perform beam dynamics calculations with tens of millions of particles, requiring over 10 GByte of core memory, in just a few hours. Also, parallel computers are becoming easier to use thanks to the availability of mature, Fortran-like languages such as Connection Machine Fortran and High Performance Fortran. We will describe our experience developing a parallel version of PARMILA and the performance of the new code.

Progress has been sufficiently good to make optically switched RF photoinjectors attractive candidates as injectors for future colliders, especially those colliders which plan to use complex beam pulse structures. Although present RF photoinjectors will not today meet all the requirements of some collider designs, their potential capabilities seem greater as well as more versatile than conventional injectors. The present status and future goals of RF photoinjectors are compared. The principal problems remaining for achieving these goals while also providing high reliability for linacs during continuous, long-term operation are examined.

One would like to meet various requirements such as high peak current, low momentum spread, high luminosity, small ratio of bunch length to plasma wavelength, and accurate timing. Meanwhile, recent development and advances in RF photoinjectors and various bunching schemes make it possible to generate very short electron bunches. Measuring the longitudinal profile and monitoring bunch length are critical to understand the bunching process and longitudinal beam dynamics, and to commission and operate such short bunch machines. In this paper, several commonly used measurement techniques for subpicosecond bunches and their relative advantages and disadvantages are discussed. As examples, bunch length related measurements at Jefferson Lab are presented. At Jefferson Lab, bunch lengths as short as 84 fs have been systematically measured using a zero-phasing technique. A highly sensitive Coherent Synchrotron Radiation (CSR) detector has been developed to noninvasively monitor bunch length for low charge bunches. Phase transfer function measurements provide a means of correcting RF phase drifts and reproducing RF phases to within a couple of tenths of a degree. The measurement results are in excellent agreement with simulations. A comprehensive bunch length control scheme is presented.

Beam size and intensity goals for 1996 were 2.1 x 0.6 mu m (x,y) at 4.0x10 (10) particles per pulse. Conventional profile monitors, such as scanning wires, fail at charge densities well below this. Since the beam-beam deflection does not provide single beam information, another method is needed for Interaction Region (IF) beam size optimization. The laser based profile monitor uses a finely focused 349 nm. wavelength, frequency-tripled YLF laser pulse that traverses the particle beam path about 29 cm away from the e+/e- IF. Compton scattered photons and energy degraded e+/e- are detected as the beam is steered across the laser purse. The laser pulse has a transverse size, (sigma(0),), of 380 nm and a Rayleigh range of about 5 mu m. This is adequate for present or planned SLC beams. Design ard results are presented.

The centerpiece of the upgrade is the installation of a new superconducting final doublet with a field gradient of 240 T/m, which will be placed at a distance of only 70 cm from the interaction point. In addition, several bending magnets in each final focus will be lengthened and two octupole correctors are added. A complementary upgrade of damping rings and bunch compressors will allow optimum use of the modified final focus and can deliver, or exceed, the targeted luminosity. The proposed upgrade will place the SLC physics program in a very competitive position, and will also enable it to pursue its pioneering role as the first and only linear collider.

Once the accelerator is tuned, the optimized emittances must be maintained. Slow alignment drifts will make resteering and reoptimization necessary. The frequency of these linac reoptimizations is an important parameter that determines how well the linear collider can be operated.

It impairs the SLC luminosity both by reducing the average beam overlap at the IP and by hampering precision tuning of the final focus. The origin of the fast orbit variation is not fully understood. Measurements during the 1994/95 SLC run showed that it is random from pulse to pulse, increases strongly with current and grows steadily along the SLAG linac, with a typical final rms amplitude of about half the beam size. In this paper, we investigate possible sources of the vertical orbit jitter. RP Assmann, R (reprint author), STANFORD UNIV,STANFORD LINEAR ACCELERATOR CTR,STANFORD,CA 94309, USA.

A stretched wire system in the sealed FFTB tunnel at SLAG was used to monitor beamline motion with a sub-micron resolution. In future linear colliders low frequency changes of the beamline alignment (<0.1 Hz) lead to untolerable quasistatical misalignments and betatron oscillations. Since it requires time to correct those errors, it is very important to determine how often corrections are needed. We present our measurements, discuss the systematics of the stretched wire system and compare the observations with the ATL-model for ground motion.

These linacs have energies and currents around 1 GeV and 100 mA. Linac designs using loom-temperature copper technology require significant microwave power and the cost of operation is high. Superconducting linacs, because of their insignificant wall losses, provide an attractive alternative. Recently, a superconducting design has been developed at Los Alamos National Laboratory (LANL). To make sure the high availability required by the application is satisfied, the design is based on demonstrated superconducting technology. The resulting design reduces power and operating cost, and offers high operational flexibility, high power upgradability, and low beam loss. Although a superconducting linac offers many advantages for neutron spallation source applications, a proton superconducting linac has yet to be built. Unanswered design feasibility questions concern the multipacting characteristics of elliptical cavities with beta (v/c) less than one and the effects of proton beam spill on the long-term superconducting characteristics of niobium. Both issues can be resolved by straightforward tests. RP Chan, KCD (reprint author), LOS ALAMOS NATL LAB,MS H851,LOS ALAMOS,NM 87544, USA.

For high energies, a conventional CCL follows the CCDTL. High RFQ output energy allows tailoring the transverse and longitudinal focusing strengths to match into the following structure. When the RFQ beam enters a higher-frequency structure, the DTL or CCDTL starts with a low accelerating gradient and large negative synchronous phase. The gradient and phase both ramp up gradually to higher values. Other changes later in the machine are also gradual. Beam-dynamics simulations show that these linacs require no separate matching sections. Applications include a cw 100-mA H+ beam from a 350-MHz, 6.7-MeV RFQ injecting a 700-MHz CCDTL and CCL; a 7% duty 28-mA H- beam from a 402.5-MHz, RFQ and DTL injecting 805-MHz structures; a cw 135-mA D+ beam produced by a 175-MHz, 8-MeV RFQ and DTL; and a 2.4% duty, 80-mA H+ beam using a 433-MHz 10-MeV RFQ and a 1300-MHz CCDTL. The machines take advantage of the considerable flexibility of the CCDTL. Designs can use a variety of different transverse focusing lattices. Use of two coupling-cavity orientations permits a constant period even when the number of drift tubes per cavity changes along the linac.

Part of this success can be attributed to using the EPICS (Experimental Physics and Industrial Control System) control system toolkit. The CEBAF control system is one of the largest accelerator control system now operating. It controls approximately 338 SRF cavities, 2300 magnets, 500 beam position monitors and other accelerator devices, such as gun hardware and other beam monitoring devices. All told, the system must be able to access over 125,000 database records. The system has been well received by both operators and the hardware designers. The EPICS utilities have made the task of troubleshooting systems easier. The graphical and text-based creation tools have allowed operators to custom build control screens. In addition, the ability to integrate EPICS with other software packages, such as Tcl/Tk, has allowed physicists to quickly prototype high-level application programs, and to provide GUT front ends for command line driven tools. Specific examples of the control system applications are presented in the areas of energy and orbit control, cavity tuning and accelerator tune up diagnostics.

During the past several years there has been tremendous progress on the development of 11.4 GHz (X-band) RF systems. These developments include klystrons which operate at the required power and pulse length, pulse compression systems that achieve a factor of four power multiplication and structures that are specially designed to reduce long-range wakefields. Together with these developments, we have constructed a 1/2 GeV test accelerator, the NLC Test Accelerator (NLCTA). The NLCTA will serve as a test bed as the design of the NLC is refined.

The individual cells were diamond point machined and microwave tested at KEK. The cells were diffusion bonded at SLAG. The structure has been cold tested. The time dependence of the beam induced dipole wakefields have been measured with the SLC beam in the test station ASSET. The structure is designed so that the dipole modes have an approximately gaussian density distribution in the frequency domain. This gives an approximately gaussian decrease of the wakefields for short times (about 10 ns), which is produced by the interference among the 206 modes in the lowest dipole mode band of the 206 cell structure. Without damping, however, the wakefields then rise back to a level which is approximately equal to the expected incoherent level from the 206 modes. The damping is accomplished by means of 4 rectangular slots or manifolds (approximately 5 mm by 10 mm) equally spaced in azimuth around the structure and running the full length of the structure. These manifolds act as single mode rectangular waveguides for the lowest band dipole modes, but are cut off for the accelerating mode. The manifolds are coupled to every cell in the structure, except for 3 at each end, by means of radial slots. Each of the four manifolds will have the dipole mode frequencies traveling in both directions and so are terminated on both ends. The structure will be installed in the NLC Test Accelerator this fall. RP Miller, RH (reprint author), STANFORD LINEAR ACCELERATOR CTR,M-S 26,POB 4349,STANFORD,CA 94309, USA.

The key features of this design include accelerating positrons at an L-band frequency (1428 MHz) and using a rotating positron target with multi-stage differential pumping. Positron yield simulations show that the L-band design yields at the source 2.5 times the beam intensity required at the interaction point and is easily upgradable to higher intensities required for the 1 TeV NLC upgrade. Multibunch beam loading compensation schemes in the positron capture and booster accelerators and the optics design of the positron booster accelerator are described.

The DDS is a 206 cell, nearly constant gradient structure, employing Gaussian detuning, and four symmetrically placed waveguide manifolds to damp the first-band dipole modes. We describe the manifold and output coupler design, bench measurements, and measurements with beam during the ASSET experiment. Dipole mode signals have been used to steer the beam to the structure center and minimize the wakefield kick. The fundamental and dipole mode features of the DDS depicted in Fig. 1 have been described by Miller, et al. [1]. In this work we report on the manifold coupler design and bench-measurements, as well as measurements with beam. Our primary concerns are good coupling of the dipole modes through the manifolds, and the use of the microwave signals from the manifold for measurement of the beam position.

The requirement for hands-on maintenance limits the beam spill to less than 0.2 nA/m along most of the linac. To achieve this goal, it is important to understand the effects of fabrication, installation and operational errors, establish realistic tolerances, and develop techniques for mitigating their consequences. A new code, PARTREX, statistically evaluates the effects of alignment, quadrupole field, and rf phase and amplitude errors in the linac. In this paper we review the effects of quadrupole misalignments and present two steering algorithms that minimize the potential for particle loss from the beam halo.

Previous designs for such a linac use a radio-frequency quadrupole (RFQ), followed by a drift-tube linac (DTL) to an intermediate energy and a coupled-cavity linac (CCL) to the final energy. The Los Alamos design uses a high-energy (6.7-MeV) RFQ followed by the newly developed [1] coupled-cavity drift-tube linac (CCDTL) and a CCL. This design accommodates external electromagnetic quadrupole lenses which provide a strong uniform focusing lattice from the end of the RFQ to the end of the CCL. The cell lengths in linacs of traditional design are typically graded as a function of the particle velocity. By making groups of cells symmetric in both the CCDTL and CCL, the cavity design as well as the mechanical design and fabrication is simplified without compromising the performance. At higher energies, there are some advantages of using superconducting rf cavities. Currently, such schemes are under vigorous study [2].

LEDA will be installed where the SDI-sponsored Ground Test Accelerator (GTA) was located. The first accelerating structure for LEDA is a 7-MeV RFQ operating at 350-MHz. This is then followed by several stages of a coupled-cavity Drift Tube Linac (CCDTL) operating at 700-MHz. The first stage of LEDA will go to 12-MeV. Higher energies, up to 40-MeV, come later in the program. Three 1.2-MW CW RF systems will be used to provide power to the RFQ.

This proton beam would have repetition rate of 60 Hz and a pulse length of 1 ms for a duty factor (DF) of 6%. An average/peak current of 1.25 mA/21 mA would be required for an 800 MeV beam to provide this power at this duty factor. The spallation target would reside in what is now called Area A and would use the H+ beam. The LANSCE accelerator would also be required to; simultaneously deliver H- beams to the Manuel Lujan Jr. Neutron Scattering Center (MLNSC) and the Weapons Neutron Research (WNR) facility at the requisite duty factors and currents. LANSCE currently delivers 16.5 mA peak of H+ beam at 120 Hertz, with a 625 mu S beam pulse length. H- beams are accelerated for use in MLNSC and WNR. In November of 1995, operation of the linac shifted to the LPSS pulse parameters, except for the peak current which remained at the 16.5 mA production level. In addition to delivering 800 kW of H+ proton beam to physics production targets, H- beams were simultaneously delivered to customers for the proton storage ring feeding MLNSC, and to researchers using the WNR facility. Performance of the RF powerplants for the 201.25 MHz drift tube linac (DTL), the 805 MHz side-coupled linac (SCL), and the associated electronics is described [1]. The conclusion of the experiment is that the LANSCE linac can be upgraded through modest improvements to drive a 1 MW LPSS.

The number of simultaneous beam users places heavy demands on the RF powerplant, especially the 201.25 MHz power amplifiers (PA) driving four drift tube linac (DTL) tanks. Designed nearly 30 years ago, these amplifiers have operated at up to 3 Megawatts with duty factors of 12%. The large number of power tubes in the PA and Intermediate Power Amplifier (IPA) plate modulators, the age of the cooling and control subsystems, tube manufacturing problems, and operation near maximum PA tube ratings have all affected the system reliability. By monitoring final power amplifier plate dissipation and tube vacuum, improved operating procedures have raised RF system reliability above 95% for operation periods in 1993-95. Other recent modifications and upgrades to the 201.25 MHz RF powerplant have significantly improved the operation. Higher beam current for a proposed Long Pulse Spallation Source (LPSS) cannot be delivered simultaneously with other beams at high duty factor, however. Plans are underway to develop a new final power amplifier which can use low-level RF modulation for amplitude control. With only a few power tubes, the system will deliver high peak power and duty factor, with improved DC to RF efficiency. and a simplified cooling system.

The injector consists of a 750 keV pre-injector diode followed by an electrostatic quadrupole accelerator (ESQ) which provides strong (alternating gradient) focusing for the space-charge dominated beam and simultaneously accelerates the ions to 2 MeV. The ESQ is followed by a six-quadrupole section to match the beam into the main accelerator 3-D PIC simulations, confirmed by comparing with scaled experiments, were used to generate a physics design with minimal emittance growth.

These experiments usually require higher quality beams and a better characterization than is normally required for ALS operations. This paper focuses on the beam emittance, energy tilt, and especially the longitudinal variation of the beam parameters. For instance, we want to avoid longitudinal variations at the low beta section of the BTF. On the other hand, a large energy tilt is required for post-acceleration compression of the bunch using an alpha magnet The PARMELA code was modified to calculate and display longitudinal variations of the emittance ellipse. Using the Microsoft Development Studio under Windows NT environment the code can handle a much larger number of particles than was previously possible.

The overall project is a collaboration involving five national laboratories. The Oak Ridge National Laboratory will be responsible for the target, facilities, and the conceptual design; Brookhaven National Laboratory will be responsible for the ring; Lawrence Berkeley National Laboratory will be responsible for the injector, including the RFQ and a low-energy chopper located in front of the RFQ; Los Alamos National Laboratory will be responsible for the main linac, and the Argonne National Laboratory will be responsible for the instrumentation. The facility will be built at Oak Ridge. In the first phase, the dual-frequency linac with frequencies 402.5 and 805 MHz must deliver to the accumulator ring an H- beam with nominal energy near 1 GeV, with a pulse length of about 1 ms at a repetition rate of 60 Hz, and with a nominal average beam power of at least 1 MW. The linac can be upgraded by a factor of four in beam power by increasing the de-injector current, and by funneling the beams from two 402.5-MHz low-energy linacs into the 805-MHz high-energy linac. Requirements for low beam loss in both the linac and the ring have important implications for the linac design, including the requirement to provide efficient beam chopping, which is necessary to provide low-loss extraction for the ring. The linac-design options and initial parameters will be presented, together with initial beam-dynamics simulation results.

As a result, 2.5 times more average beam current can be delivered to the Brookhaven Isotope Resource Center (BIRC), formerly called BLIP, a facility which produces radionuclides and radiopharmaceuticals for the medical community, and also supports a research program seeking more effective diagnostic and therapeutic agents. The optics of the beam transport line to BIRC was redesigned to (a) reduce transverse fluctuations of the beam at the target due to any linac energy fluctuations, (b) produce a flat beam distribution at the target, in order to avoid melting certain target materials, and (c) handle the higher beam intensity while keeping radiation levels low. A profile monitor was also modified to monitor the flatness of the beam using the algebraic reconstruction technique (ART). The above improvements will be described, and results of the commissioning of the line during the 1996 running period will be discussed.

Accelerating elements and linear space-charge forces are included. The beam is described by a 6-D sigma matrix of second moments. We have extended the capabilities of this code to include effects, such as wakefields, related to the variation of the beam bunch in the longitudinal direction. This nonlinear capability was implemented by adding centroid tracking and describing the beam by a collection of slices, each described by a 6-D centroid and sigma matrix. External forces, space-charge forces, and wakefields act on the collection of beam slices. Results are presented in terms of an overall sigma matrix, computed by combining the slice distributions. The new TRACE 3-D has been integrated with an improved graphic user interface (GUI) based on the Shell for Particle Accelerator Related Codes. This new approach to modeling wakefields demonstrates the flexibility of extending the capabilities of moment codes to handle important physical effects, and the rapid incorporation of the new capabilities into the graphic interface illustrates the ease of customizing the new GUl. The wakefield model and features of the new interface are presented. RP Lysenko, WP (reprint author), LOS ALAMOS NATL LAB,AOT-1,MS H808,LOS ALAMOS,NM 87545, USA.

For copper (non-superconducting) accelerator structures, this implies a high peak power per unit length and a high peak power per RF source, assuming a limited number of discrete sources are used. To provide this power, a number of devices are currently under active development or conceptual consideration: conventional klystrons with multi-cavity output structures, gyroklystrons, magnicons, sheet-beam klystrons, multiple-beam klystrons and amplifiers based on the FEL principle. To enhance the peak power produced by an rf source, the SLED rf pulse compression scheme is currently in use on existing linacs, and new compression methods that produce a flatter output pulse are being considered for future linear colliders. This paper covers the present status and future outlook for the more important rf power sources and pulse compression systems. It should be noted that high gradient electron linacs have applications in addition to high-energy linear colliders; they can, for example, serve as compact injectors for FEL's and storage rings.

The extent of dissociation width of an ordinary dislocation is calculated to be larger at alpha(2)/gamma and gamma/gamma interfaces by about two-fold as compared to the bulk of gamma-phase, suggesting the enhanced slip along the interfaces when the crystal is at a soft orientation. Propagation of (111) cleavage cracks is influenced by the mixed mode (II and III) of external loading applied to the coplanar deformation twinning and ordinary slip, leading to translamellar fracture. According to the calculated interfacial fracture energies, cleavage cracking is to occur on alpha(2)/gamma boundaries and least likely on true-twin boundaries. Discussion is given on the roles of misfit dislocations, kinetics of dislocation-interface interactions, and hydrogen embrittlement in deformation and fracture processes.

Recent studies indicate that binary Ni(3)AI is intrinsically quite ductile at room temperature, and its poor tensile ductility and brittle grain-boundary fracture are caused mainly by moisture-induced hydrogen embrittlement when the aluminide is tested in ambient air. Boron additions suppress environmental embrittlement and enhance grain-boundary cohesion, resulting in a dramatic increase of tensile ductility at room temperature. Both B-doped and B-free Ni3Al alloys exhibit brittle intergranular fracture and low ductility at intermediate temperatures (300-850 degrees C) because of oxygen-induced embrittlement in oxidizing environments. Chromium is found to be most effective in alleviating elevated-temperature embrittlement. Parallel efforts on alloy development using physical metallurgy principles have led to the development of several Ni3Al alloys with promising mechanical and metallurgical properties for structural use.

In particular, the role of extrinsic crack-tip shielding on crack propagation under monotonic and cyclic loading is contrasted with intrinsic damage mechansims, both at ambient and elevated temperatures. For example, the fracture and fatigue properties in a toughened SiC ceramic are almost exclusively controlled by extrinsic shielding; marked resistance-curve toughening is achieved under monotonic loading by grain bridging, which is severely diminished under cyclic loading through progressive wear at the sliding grain interfaces. Cyclic crack growth rates in ceramics, as a result, are extremely sensitive to K-max and less dependent on Delta K at room temperature. At elevated temperatures, behavior in ceramics is influenced by extrinsic and intrinsic effects associated with deformation and damage of grain boundary amorphous films. Conversely, damage tolerance characteristics of intermetallics like TiAl, TiNb/TiAl and Nb/MoSi2 are found to be a function of both intrinsic and extrinsic mechanisms, intermediate to behavior in metals and ceramics at ill temperatures. Extrinsically, ductile-particle and shear-ligament bridging are dominant under monotonic loading and become less effective under cyclic loading; crack-propagation rates are moderately sensitive to both Delta K and K-max. From an intrinsic stand point, fatigue properties of gamma-TiAl intermetallic alloys are slightly degraded in the 600-650 degrees C range, just below the ductile-to-brittle transition temperature for TiAl. The strong dependence of cyclic crack growth rates on the applied stress intensity (K-max or Delta K) in advanced ceramics and intermetallics necessitates the use of design and life-prediction procedures based on crack initiation, small crack or fatigue-threshold philosophies.

Metallurgical knowledge of microstructure development in titanium aluminide alloys based on both the alpha(2) and gamma phases is now fairly extensive. Moreover, broadened knowledge of hydrogen effects makes possible a more complete description, though not yet entirely realistic modeling, of fracture phenomena. Hydrides can form in these alloys at rather high hydrogen contents, but of more interest for possible applications are effects at much lower hydrogen contents. Then, the primary microstructural effect in the at phase (when the alloy is based on at) is precipitation of orthorhombic or O phase which is stabilized by hydrogen. In TiAl-based alloys, typical microstructures are a mixture of alpha(2) and gamma phases, and hydrides having either of hive crystal structures, FCC or tetragonal can form. In alpha(2) alloys which contain either beta or B2 phase, no hydride precipitation has been reported in the beta or B2, but O phase can form. Accordingly, hydrogen fracture behavior for all these alloys must be interpreted by a combination of effects due to hydrogen in solution and to the presence of O phase, and when present, hydrides as well.

Reaction between the environment and the fiber/matrix interphase is of primary concern because this will affect the structural properties of these composites. The effects of Ar+O-2 and Ar+H-2 environments on the weight loss and crack growth rates of SiC/SiC CFCCs have been determined and a model that correlates the time-dependent debonding resulting from the environmental reactions and the crack growth rates is presented. Boron nitride (BN) interphases were shown to be more stable than carbon (C) in Ar+O-2 environment for concentrations up to 10% of air as observed by a factor of 10 slower crack velocity at 1373 K for a CFCC with a BN-interphase as compared to a C-interphase. A factor of 10 lower weight loss was found for a CFCC with a C-interphase in Ar+H-2 environments of 100 and 1000 Pa H-2 as compared to an Ar+10 Pa O-2 environment, interactions with the environment will introduce a number of design issues for the application of SiC/SiC CFCCs including: 1) time-dependent elastic properties, 2) reduced matrix cracking stress, 3) accelerated creep rates, 4) reduced fatigue strength, 5) increased subcritical crack growth rates and 6) reduced hermetic properties. The novel properties of these materials can be used beneficially by the designer but will also provide a challenge in their application while environmental interactions will increase the challenge in their use.

Scales developed on the oxidized materials are characterized and related to observed mass gain. B-Mo5Si3 maintains excellent oxidation resistance up to 1450 degrees C with an overall mass gain of 0.06 mg/cm(2) after fifty hours. Ti5Si3O0.25 also maintains good oxidation resistance up to 1306 degrees C with an overall mass gain of 1.1 mg/cm(2) after 240 hours, Boron and carbon additions to V5Si3 improve oxidation resistance with overall behavior at 1000 degrees C similar to that of undoped Ti5Si3.

Silicon-based oxide, nitride, and oxinitride coatings were prepared by IBAD. During annealing, the silicon diffuses into and reacts with the substrate to form a metal-silicide. To verify the scale-forming mechanism, oxidation tests (at temperatures of 700-1000 degrees C and oxygen partial pressure of 10(-4) atm) were performed on substrates with and without the coating layer. The results showed that Cr2O3 was formed as the outer scale and that a thin SiO2 layer was observed at the alloy/scale interface. Based on these results, an alternative surface-modification approach was tried. A durable protective coating for high-temperature alloys was achieved by CVD followed by chemical reaction in a controlled environment. By thermogravimetric analysis with a microbalance, several oxidation/sulfidation tests (at 700 and 1000 degrees C) were performed with and without the coating on Fe-25Cr-1Ce and Fe-25Cr-1Y. After each run, samples were examined by scanning electron microscopy, energy-dispersive X-ray analysis, and Auger and X-ray photoelectron spectroscopy. The results elucidated the nature of the protective coating that provides high-temperature corrosion protection. C1 Argonne Natl Lab, Div Energy Technol, Argonne, IL 60439 USA.

One potential economical method of obtaining a high volume fraction of dispersed TiC particles in an iron matrix is through the solidification processing of an Fe-Ti-C melt. However, simply adding titanium into an iron-carbon melt has two consequences. The first results in the formation of TiC particles at much higher temperatures than the solidification temperature of the iron alloy. Second, the TiC particles separate from the melt as a result of the large density difference between TiC particles and the molten iron. Therefore, a method was developed to incorporate the titanium by adding it to the molten iron-based mixture in-the-mold (hereafter referred to as in mold). This procedure allows the molten metal to react with the titanium just before solidification occurs. Research indicates that the incorporation of the titanium into the melt very late in the solidification process facilitates the formation of a more homogenous microstructure with a uniform distribution of TiC particles. The effect of weight fraction and particle size of ferrotitanium, molten alloy pouring temperature, and base alloy composition is discussed with respect to the size and distribution of TiC particles in the composite material.

These techniques, used either separately orjointly, have become standard tools in combustion research. Flames with simple streaming flows as well as complex hows with recirculating zones are discussed for a variety of fuel mixtures and a range of turbulent mixing rates. The chemistry-turbulence interaction and other related issues like local dame extinction and the bimodality of the approach toward blowoff are discussed. Additional single-point data are also presented illustrating the effects of partially premixing the fuel with air, diluting it with nitrogen or adding methane to a mixture of nonhydrocarbon fuels. The bimodality of the conditional pdfs of various reactive scalars as the dames approach blowoff, and the start of occurrence of localized extinction, are correlated with two simple parameters: (a) the stoichiometric mixture fraction, xi(s), and (b) the reaction zone width, Delta xi(R). The latter parameter may be easily determined from standard laminar dame calculations for a given fuel mixture. Copyright (C) 1996 Elsevier Science Ltd.

The method is based on a linearization of the two-body part of the Hamiltonian in an imaginary-time propagator using the Hubbard-Stratonovich transformation. The foundation of the method, as applied to the nuclear many-body problem, is discussed. Topics presented in detail include: (1) the density-density formulation of the method, (2) computation of the overlaps, (3) the sign of the Monte Carlo weight function, (4) techniques for performing Monte Carlo sampling, and (5) the reconstruction of response functions from an imaginary-time auto-correlation function using MaxEnt techniques. Results obtained using schematic interactions, which have no sign problem, are presented to demonstrate the feasibility of the method, while an extrapolation method for realistic Hamiltonians is presented. In addition, applications at finite temperature are outlined. C1 UNIV TENNESSEE, DEPT PHYS, KNOXVILLE, TN 37996 USA. OAK RIDGE NATL LAB, OAK RIDGE, TN 37831 USA.

We assume (i)technicolor-like scenario for inducing W mass, and (ii)an effective 4-fermi interaction for inducing top mass. With these minimal assumptions, we obtain lower bound for the strength G and the upper bound for the intrinsic mass scale M of the 4-fermi interaction (ii), as we vary the interaction (i). We find that the coupling is strong, G/4 pi similar to O(1). From the tree-level unitarity constraint it is suggested that M should be of the order of Lambda(TC) similar or equal to 1 similar to 2 TeV or less. We also study the consistency with the present T parameter data, and obtain another upper bound for M. Using the obtained result, we estimate the non-standard-model correction to the polarized cross section for gamma gamma --> (t) over bar t at O(G). e.g. The correction exceeds 8% at root s = 1 TeV for the case N-TC = 3.

The only assumptions in this argument are: (1) hidden sector supersymmetry breaking, (2) genericity, namely the existence of all operators allowed by symmetries without any particular relations among coupling constants, and (3) breakdown of global symmetries at Planck scale. An explicit example of a model of flavor is presented whose symmetry group is S-3. It will be shown that this flavor group allows us to understand the hierarchical structure of Yukawa matrices by a sequential symmetry breaking, while suppressing the flavor-changing neutral currents well below the experimental constraints. Extension of the model to the lepton sector is also discussed. The mu --> e gamma rate and proton decay rate are roughly on the edge of experimental constraints. Interestingly enough, the dominant proton decay mode is p --> K(0)e(+), which is distinctive from other models (pi(O)e(+) in non-SUSY GUT, K+<(nu)over bar(mu)> in SUSY GUT).

In such a model, Polonyi held can weigh as Q(10TeV) and decay just before the big-bang nucleosynthesis. It is shown that in spite of a large entropy production by the decay of the Polonyi held, one can naturally explain the present value of the baryon-to-entropy ratio, n(B)/s similar to (10(-10) - 10(-11)) if the Affleck-Dine mechanism for baryogenesis works. It is pointed out, however, that there is another cosmological problem related to the abundance of the lightest superparticles produced by the decay of the Polonyi field.

The most mysterious aspect of phenomenological supersymmetry is the mechanism of spontaneous supersymmetry breaking. This mechanism ties the observable pattern of supersymmetric particle masses to aspects of the underlying unified theory at very small distance scales. In this article, I will discuss a systematic experimental program to determine the mechanism of supersymmetry breaking. Both pp and e(+)e(-) colliders of the next generation play an essential role.

Detailed crystal structure information is available for CRP:(cAMP)(2) and for CRP:(cAMP)(2) complexed with DNA. In the crystalline environment, CRP:(cAMP)(2) subunits are asymmetrically related; one subunit has a closed conformation and the other has an open conformation. The CRP:(cAMP)(2) complexed with DNA shows both subunits in a closed conformation. We have studied the molecular dynamics of CRP:(cAMP)(2) in noncrystalline environments. CRP:(cAMP)(2) was simulated for 625 ps in vacuo and for 140 ps in solution. The crystal structure of CRP:(cAMP)(2) in the absence of DNA was used as the initial conformation. Molecule optimal dynamic coordinates (MODCs) (Garcia A, 1992, Phys Rev Lett 68:2696) were used to analyze protein conformations sampled during the course of the simulations. Two MODCs define a transition of the open subunit to a closed subunit conformation during the first 125 ps of simulation in vacuo; the resulting subunit conformation is similar to that observed in CRP:(cAMP)(2):DNA crystals. Simulation of CRP:(cAMP)(2) in solution showed that a transition from the open to the closed state also occurs when water is explicitly included in the calculations. These calculations suggest that the asymmetric conformation of CRP:(cAMP)(2) is stabilized by crystal lattice interactions. The predicted solution conformation is more symmetric, with both subunits in a closed conformation. C1 TEXAS TECH UNIV,DEPT CHEM & BIOCHEM,LUBBOCK,TX 79409.

All subjects showed almost identical uptake of C-11 labeled drug in brain, as well as a very similar decrease in binding of [C-11]methylphenidate in basal ganglia, after pretreatment with methylphenidate. In contrast, the magnitude of the behavioral and cardiovascular changes induced by methylphenidate varied among the subjects, The temporal course for methylphenidate effects paralleled closely the pharmacokinetics of [C-11]methylphenidate in brain for the perception of ''restlessness'' and for changes in systolic blood pressure and heart rate. In contrast, methylphenidate induced ''high'', ''anxiety'' and changes in diastolic blood pressure decreased rapidly despite long lasting binding of the drug in brain, These results indicate that binding of methylphenidate in brain does not appear to predict individual responses to the drug and that more than one neurotransmitter and/or adaptation process are likely to be involved in the behavioral and cardiovascular effects of methylphenidate.

Previous work indicated that these buried carbonate paleosols constitute a relatively continuous, low-permeability paleosurface. The distribution of the Pliocene-Pleistocene deposits containing the paleosols depends in part on erosion of the underlying Miocene-Pliocene fluvial/lacustrine Ringold Formation and post-depositional erosion by the catastrophic Missoula floods. The character of the 'caliche' layer(s), as determined from cores, varies across the study area: from 0-20 m in thickness; at depths of 20 m in the south, to 65 m in the northwest; bounded above and below by irregular surfaces with as much as 25 m relief; and in general co-varies in number of carbonate layers with the thickness of the deposits. These carbonate layers reflect the geomorphology and hydrology existing during the time they developed. I interpret these carbonate layers as paleosols but recognize morphologic features that indicate modification may have occurred after initial development at the surface. These include the absence of associated soil horizons; no apparent decrease in carbonate content with depth in some of the carbonate layers; and unusual Bk horizon fabrics (including crystalline or popcorn-like forms). These features and fabric differences influence potential flow pathways of waste fluids. C1 ASSOCIATED WESTERN UNIV,NW DIV,RICHLAND,WA 99352. LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87545.

In the austenitic, low carbon steels of interest in this work, the phase transformations often induce additional macroscopic plasticity which can have substantial effects on both residual stresses and distortions. The modeling strategy adopted here couples differential equations for phase evolution with a multiphase macroscopic state variable material model. The kinetic rate equations for each product phase are derived using a thermodynamic formulation and fit to experimental data. Contrary to classical modeling of transformation plasticity, the material model used is based on mixture theory wherein we track the behavior of individual phases. Phase interactions are accounted for by introducing an internal stress that models both the macroscopic multiphase behavior and effects driven by the transformation. The form of the internal stress is based on discrete, micromechanical simulations of the response of a transforming representative volume. The kinetics model is fit and tested using time temperature transformation (TTT) and continuous cooling transformation (CCT) data, and by studying the influence of stress on the kinetics through compression and tension experiments. The transformation plasticity and multiphase composite behavior predicted by the material model is validated by dilatometry and fixed volume fi action mechanical tests performed on a representative low carbon steel alloy. Finally, the model is exercised in large scale finite element simulations to capture the stress response and predict distortions during quenching of disks and long, annular cylinders.

By extrapolation it is estimated that the equilibrium constant at 1 bar and 20 degrees C is approximately 10 molal(-1). The reaction volumes range from -95 to -122 cm(3)/mol. These volumes are attributed to the volume of electrostriction by the butadiene anion.

This possibility is the result of a recent breakthrough in the ultra-separation of nickel from copper and the measurement of Ni-63 using accelerator mass spectrometry (AMS). The reaction, Cu-63(n,p)Ni-63, results in the production of Ni-63 (half life, 100 y) by neutrons above similar to 1 MeV. A laboratory test experiment demonstrates that this reaction can now be used to reconstruct the high energy neutron fluence in Hiroshima, which would eliminate the most serious obstacle that has prevented a credible solution to the DS86 neutron dosimetry problem.

Unless they are energy compensated, a significant over-response occurs below 200 keV. At least one manufacturer (Siemens) is using three diodes in parallel with individual filters to produce excellent energy and angular response. It is also possible to use an algorithm based on the photon spectrum of a single diode to flatten the energy response. However, the more cost effective commercial practice is to use a single diode with a simple filter to flatten the energy response-with the major disadvantage of sacrificing low energy photon response. The technique of using a filter with an opening has been used previously, typically for energy compensating GM detectors and proportional counters. A new variation of this technique has been investigated, which not only compensates the energy response of a silicon PIN diode but also maintains an extended low energy response. The technique consists of using a composite filter of two or more materials together with several openings whose individual area is in the range of 15% to 25% of the diode's active area. One of the openings is centred over the diode's active area, while the others are located al the periphery of the active area to preserve a good polar response to +/-45 degrees. Monte Carlo radiation transport methods were used to simulate the coupled electron-photon transport through a Hamamatsu S2506-01 diode and to determine the energy response of the diode for a variety of filters. Composite filters were designed, and optimised for both current and pulse mode operation of the diode. In current mode, the resultant dosemeter energy response relative to air dose was within -15% and +30% for 0 degrees incidence over the energy range from 15 keV to 1 MeV. For +/-45 degrees incidence, the energy response was within -30% and +20% relative to air dose from 30 keV to 1 MeV. In pulse mode, the resultant dosemeter energy response was within -25% and +50% for 0 degrees incidence over the energy range from 30 keV to 10 MeV. For +/-45 degrees incidence, the energy response was within -25% and +40% from 40 keV to 10 MeV. This filter technique is applicable to a variety of silicon diodes. The work and results described in this paper are intended to show the theoretical viability of the filter technique.

As SR facilities are rapidly being built all over the world, they introduce the need for low energy X ray dosemeters because of the potential radiation exposure to experimenters. However, they also provide a unique opportunity for low energy X ray dosimetry studies because of the availability of monochromatic X ray beams. Results of such studies performed at the Stanford Synchrotron Radiation Laboratory are described Lithium fluoride TLDs (TLD-100) of varying thicknesses (0.015 to 0.08 cm) were exposed free-in-air to monochromatic X rays (7 to 17.5 keV). These exposures were monitored with ionisation chambers. The response (nC.Gy(-1)) was found to increase with increasing TLD thickness and with increasing beam energy. A steeper increase in response with increasing energy was observed with the thicker TLDs. The responses at 7 and 17.5 keV were within a factor of 2.3 and 5.2 for the 0.015 and 0.08 cm thick TLDs, respectively. The effects of narrow (beam size smaller than the dosemeter) and broad (beam size larger than the dosemeter) beams on the response of the TLDs are also reported.

The ability to re-analyse a dosemeter and to perform necessary exposure diagnostics familiar to film dosimetrists are also desirable qualities of a dosimetric system. Battelle has developed a cooled optical luminescence dosimetry (COLD) system that allows all these features to be combined into one practical dosimetry system. COLD technology uses an extremely sensitive phototransfer mechanism manifested in certain solid state materials. Modest cooling below room temperature is required during the readout of the COLD detectors. Excitation with a laser or other light source is required to initiate the phototransfer process. Warming to near room temperature liberates the luminescence that is proportional to the radiation exposure. Due to the low readout temperatures, COLD phosphor materials can be packaged in polymers without fear of melting the polymer matrix, as would occur using a thermoluminescent process. Besides extreme sensitivity (minimum detectable exposure levels of 0.1 mu Sv are possible), the detectors can be re-analysed with minimal loss of signal. An imaging film is created by the mixture of small grains of COLD phosphor in the polymer matrix. A sensitive CCD or microchannel PMT device acquires a two-dimensional image of the dosemeter luminescence. The resulting digital image can then be mathematically interrogated to determine exposure diagnostics in the same way that film is currently used.

Single and dual element TLD dosemeters, ranging in thicknesses from 20 to 100 mg.cm(-2), and appropriate filtration comprise the extremity detectors which are uniquely identified by bar code labels. A dose algorithm used in conjunction with the dosemeters and TLD reader technology are capable of reporting shallow dose H-p(0.07) from betas, low and high energy photons using any combination of these dosemeters. Performance tests and results were obtained by the Idaho National Engineering Laboratory (INEL) Operational Dosimetry Unit in the evaluation of a single extremity dosemeter capable of simultaneously monitoring beta and high energy gamma. Four TL materials and two filter types were tested in various combinations to Cs-137 photons, uranium slab, Sr-90/Y-90, and Tl-204 beta, irradiations. An overview of the current INEL system dosemeter response, linearity, angular dependence, residual, and effects of physical damage to the dosemeter were tested. The results of these tests, presented here, lead to the preliminary conclusion that an extremity dosemeter can be constructed to monitor beta and high energy gamma radiation simultaneously.

While the technique works well, the complications and cost of using ESR machines could be simplified by using optically stimulated luminescence (OSL) techniques. Battelle, in collaboration with Landauer, Inc., has been developing low cost OSL polymer detectors manufactured by either injection moulding or extrusion. LiF and Al2O3 are the OSL active materials that are uniformly mixed with a polymer prior to dosemeter fabrication. Grain sizes of the LIF are usually kept below 10 mu m in order to disperse the material uniformly. Plastic manufacturing techniques readily produce uniform detectors. The aim of the project is to produce an inexpensive detector that covers the range of IO R-10(6) R. Readout is accomplished using a laser or light source to excite the OSL radiation damage centres. Luminescence of the OSL radiation damage centres is measured by optical filtration of the laser or light source. The method of fabrication, readout techniques, and dosimetric response of the new detectors are presented. RP Miller, SD (reprint author), PACIFIC NW LAB, POB 999, MS K3-55, RICHLAND, WA 99352 USA.

The initial calibration of the commercially available him was performed using Co-60 gamma rays. A comparison of simultaneously irradiated bare dosemeters and dosemeters mocked to simulate the liquid samples shows the importance of irradiation of dosemeters under conditions as nearly identical to that of the actual samples as possible. In addition, the dosemeter response to absorbed dose for two different batches of GafChromic film, to different temperatures at the time of irradiation and to delay before readout, was examined.

The measurements were made especially challenging by vagaries of the weather, blowing soil, moisture condensation, radon in soil gas, and the need to leave the detectors in place for periods of up to several days. The most successful approach made a differential measurement on scrapings of surface soil loaded into two Petri dishes covered with thermal insulators. One dish was covered with a radon-permeable Tyvek sheet while the other was left uncovered. The Tyvek sheet interrupts alpha particles emitted by plutonium and other transuranics and background actinides. The difference in the two measurements is then due to these two groups of alpha emitters. Using this in situ, passive measuring method, background measurements were made down to a few tens pCi.g(-1). Site-specific samples of soil were ground to improve homogeneity, analysed radiochemically for alpha-emitting isotopes and the calibration factors then determined for the EICs and ATDs.

For potential application in mixed neutron-gamma fields, the relative neutron:gamma sensitivity, k(u), of these thermoluminescence dosemeters (TLDs) was measured, along with that of the widely used TLD-700 ((LiF)-Li-7:Mg,Ti) for comparison. Narrow spectra neutrons of energies from 0.3 to 14 MeV produced by a Van de Graaff accelerator were used to irradiate pairs of TLDs. The neutron and gamma doses were measured independently using a tissue-equivalent ionisation chamber in combination with a compensated Geiger-Muller detector. For neutron energies from 0.3 to 6.0 MeV, the k(u) of Al2O3:C was about one tenth of that of TLD-700. The k(u) of (LiF)-Li-7:Mg,Cu,P was about one third that of TLD-700 for the same neutron energy range. All phosphors showed greater response to 14 MeV neutrons, but the relative neutron:gamma sensitivity of the newer phosphors was one third to one fifth that of TLD-700.

Thin-layer BeO on a conductive graphite substrate is of the order of 50 times more sensitive to tritium than the EIC. At the US Department of Energy release limit for fixed surface tritium of 5000 dpm per 100 cm(2), the exposure time for quantification with the exoelectron dosemeter is of the order of one hour. A multipoint Geiger counter was used for reading exoelectron emission. An alternative ceramic BeO dosemeter (Thermalox 995) has low electrical conductivity and will require a different reader to overcome problems of surface charging during exoemission. The electret is very easy to use and read. Its practical use will be for surfaces with relatively high levels of tritium contamination.

The scheme employs the modified form of the vector Helmholtz equation for the scattered electric fields to model variations in electrical conductivity, dielectric permitivity and magnetic permeability. The use of the modified form of the Helmholtz equation allows for perfectly matched layer (PML) absorbing boundary conditions to be employed through the use of complex grid stretching. Applying the finite difference operator to the modified Helmholtz equation produces a linear system of equations for which the matrix is sparse and complex symmetrical. The solution is obtained using either the biconjugate gradient (BICG) or quasi-minimum residual (QMR) methods with preconditioning; in general we employ the QMR method with Jacobi scaling preconditioning due to stability. In order to simulate larger, more realistic models than has been previously possible, the scheme has been modified to run on massively parallel (MP) computer architectures. Execution on the 1840-processor Intel Paragon has indicated a maximum model size of 280 x 260 x 200 cells with a maximum hop rate of 14.7 Gflops. Three different geologic models are simulated to demonstrate the use of the code for frequencies ranging from 100 Hz to 30 MHz and for different source types and polarizations. The simulations show that the scheme is correctly able to model the air-earth interface and the jump in the electric and magnetic fields normal to discontinuities. For frequencies greater than 10 MHz, complex grid stretching must be employed to incorporate absorbing boundaries while below this normal (real) grid stretching can be employed.

Using the uranium L(III)-edge extended X-ray absorption fine structure (EXAFS) and infrared (IR) spectroscopies as probes of the local structure around the uranium, a trend is observed whereby the axial oxygen bond lengths from the uranyl groups increase from 1.80 Angstrom at pH = 7 to 1.86 Angstrom at pH = 11. Shifts in the IR spectral frequencies support this assignment. A concomitant decrease in the equatorial oxygen and nearest-neighbor uranium bond lengths also occurs with increasing pH. Expansion of the linear O=U=O group is seen directly at the L(III) absorption edge where multiple scattering resonances systematically shift in energy. EXAFS curve-fitting analysis on these precipitates and a sample of synthetic schoepite indicate that the structure of the species formed at pH = 7 is similar to the structure of schoepite. At pH = 11, the precipitate structure is similar to that of a uranate. C1 LAWRENCE LIVERMORE NATL LAB,GT SEABORG INST TRANSACTINIUM SCI,LIVERMORE,CA 94551.

The surface studies showed that the hydrolysis trend in the group 4 elements and the pseudogroup 4 element, Th, decreases in the order Rf > Zr approximate to Hf > Th. This unexpected trend was attributed to relativistic effects which predict that Rf(4+) would be more prone to having a coordination number (CN) of 6 than 8 in aqueous solutions due to a destabilization of the 6d(5/2) shell.

Since bromide is a larger and softer (more polarizable) anion than chloride, the stability of Rf-bromide complexes was expected to differ from the stability of Rf-chloride complexes, and a comparison of the two systems was undertaken. Our studies showed that the extraction trend decreased in the order Zr > Hf > Rf/Ti for HBr, compared to Zr > Hf > Rf > Ti for HCl, showing that Rf and Ti did not extract as well in either system, probably because they hydrolyzed more easily than Zr and Hf.

This extraction system was of particular interest because all group 4 cations studied formed complexes with the same coordination number (CN) of 6. Therefore, species extracted were similar and the extractability depends on the radii of the fluoride complexes. The studies showed that the extractability for the group 4 elements in this system decreases in the order Ti > Zr approximate to Hf > Rf, in inverse order from the decrease in ionic radii Rf > Zr approximate to Hf > Ti. This order is different than the order in the hydrolysis, TBP-HCl, and TBP-HBr extraction systems where Rf, due to decreasing CN, behaves more similarly to Ti than to Zr and Hf.

A thermodynamic model, based on Fitter's specific ion-interaction approach, was developed to interpret the solubility of NaNd(CO3)(2) . 6 H2O(c) as functions of sodium carbonate and sodium bicarbonate concentrations. In this model, the solubility data of NaNd(CO3)(2) . 6 H2O(c) were explained by assuming the formation of NdCO3+, Nd(CO3)(2)(-) and Nd(CO3)(3)(3-) species and invoking the specific ion interactions between Na+ and Nd(CO3)(3)(3-). Ion interaction parameters for Na+-Nd(CO3)(3)(3-) were developed to fit the solubility data. Based on the model calculations, Nd(CO3)(3)(3-) was the predominant aqueous neodymium species in 0.1 to 2 M sodium carbonate and 0.1 to 1 M sodium bicarbonate solutions. The logarithm of the NaNd(CO3)(2) . 6 H2O solubility product (NaNd(CO3)(2) . 6 H2O(c) = Na+ + Nd3+ + 2 CO32- + 6 H2O) was calculated to be -21.39.

Experiments were prepared from oversaturation by adding an excess of NpO2+ or NpO22+ to the brines and allowing the neptunium solids to precipitate. Vessels were maintained in contact with fixed CO2(g) partial pressures at constant pH and 24+/-1 degrees C. Dissolved Np(V) concentrations decreased several orders of magnitude within the first 100 days of the experiment, while dissolved Np(VI) concentrations decreased initially but then remained relatively constant for more than 400 days. The solid phases formed in all experiments were identified by X-ray powder diffraction as KNpO2CO3 . xH(2)O(s). Steady state concentrations for Np(V) are similar to those observed for Pu(V) in the same brines under the same conditions, where Pu occurs predominantly as Pu(V). Similarly, steady state concentrations for Np(VI), which was not reduced over a two year period, compare well with measured Pu(VI) concentrations in the same brines before the Pu(VI) was reduced to Pu(V).

A consistent model for the deprotonation constants of acetic acid in NaCl and NaClO4, media was developed. For the concentrations of acetate expected in a waste repository, only the neutral complex NpO2Ac(aq) was important in describing the interactions between the neptunyl ion and acetate. The thermodynamic stability constant beta(101)(0) for the reaction NpO2+ + Ac- <----> NpO2Ac was calculated to be 1.46+/-0.22.

Complexation with chelating agents generally stabilizes the radionuclide in a soluble form, which may increase migration. This study provides fundamental knowledge of the behavior of plutonium in the presence of nitrilotriacetic acid (NTA) and ethylenediaminetetraacetic acid (EDTA). These complexing agents have been identified as contaminants in the mixed organic-radionuclide waste at U.S. Department of Energy (DOE) sites. We studied the complexation behavior of the different oxidation states of plutonium: Pu(III), Pu(IV), Pu(V), and Pu(VI) in the presence of NTA and EDTA at various concentrations of plutonium and several Pu/organic-chelating ratios. We found that Pu(IV) is the predominant oxidation state at pH 5 to 8. Pu(III) was oxidized and Pu(V) and Pu(VI) were reduced. We found that the presence of NTA and EDTA in plutonium solution stabilizes plutonium in soluble form and therefore enhances its potential migration in the subsurface.

Soils were well-characterized, and the distributions of naturally-occurring elements as well as contaminants were determined in each operationally-defined extract. This approach provided experimental evidence required to understand which of the soil phases dissolved in each step. Since U and Pb can also occur in soils naturally, knowledge of the dissolution of insoluble soil phases and the fractions of U and Ph associated with these phases allows an estimation of the amount of contaminant that is unavailable for transport in the aqueous phase under normal geochemical conditions. This approach provided a more representative estimate of ''background'' or residual concentrations of contaminants than determination of total contaminant concentrations in soils collected from uncontaminated areas. Comparisons between the two sequential techniques were also possible, with both methods indicating consistent trends. A simplified five-step method tended to provide lower estimates of metals bound within the refractory soil matrix. C1 GEORGIA INST TECHNOL, SCH MECH ENGN, NUCL ENGN PROGRAM, ATLANTA, GA 30332 USA.

Uranyl orthosilicate was investigated as a reference for EXAFS studies of similar but non-crystalline uranium, oxygen, and silicon containing samples. Fitting the EXAFS spectrum yields the following distances for the first four coordination shells of uranium: U-O-ax = 1.79 Angstrom, U-O-eq = 2.38 Angstrom, U-Si = 3.16 Angstrom, and U-U = 3.88 Angstrom. These values agree well with results from single-crystal X-ray diffraction (XRD) measurements. Structural parameters of light elements such as oxygen and silicon at distances greater than 3.5 Angstrom could not he detected without a priori knowledge of their presence. The EXAFS spectra of uranyl species sorbed at pH 4 onto silicic acid and silica gel are identical indicating similar uranyl coordination. The main characteristic of the surface species are two well-separated oxygen coordination shells in the equatorial uranyl plane at 2.27 and 2.50 Angstrom. The results of the EXAFS analysis favor the interpretation of the uranyl surface species as an inner-sphere, mononuclear, bidentate complex.

The 15-s Nb-99g was produced from a U-235-fission target at a reactor neutron beam line and 34-s (262)Ha in fusion reactions of O-18 + Bk-249. The reaction products were continuously and rapidly transported to the chromatography apparatus with a carbon aerosol gas-jet system using He as carrier gas. Volatile chloride molecules were formed in a 900 degrees C reaction oven by adding HCl as reactive gas. Depending on trace amounts of O-2 in the system, either the pentachlorides or the oxytrichlorides, or a mixture thereof, were formed. The isotopes Nb-99g and (262)Ha were unambiguously identified after gas chromatographic separation by measuring the characteristic gamma-lines of Nb-99g and by registering (262)Ha-Lr-258 mother-daughter alpha-alpha correlations as well as spontaneous fission decays, respectively. The adsorption enthalpies of the investigated species on quartz surfaces were determined by analyzing the measured retention curves with a Monte Carlo model. Using an empirical correlation, the adsorption enthalpies were converted to sublimation enthalpies. The sublimation enthalpies of 95 +/- 16 kJ . mol(-1) and 124 +/- 16 kJ . mol(-1) determined for NbCl5 and NbOCl3, respectively, were in good agreement with literature data. In experiments with Ha-chlorides a yield curve with two components was observed. Sublimation enthalpies of less than or equal to 120 kJ . mol(-1) and 152 +/- 18 kJ . mol(-1) were estimated for HaCl(5) and HaOCl(3), respectively. The estimated sublimation enthalpies were compared with theoretical predictions from relativistic calculations and with empirical extrapolations of chemical properties. In agreement with empirical extrapolations, a lower volatility was found for HaOCl(3), than for NbOCl3. C1 UNIV BERN,LAB RADIO & UMWELTCHEM,CH-3012 BERN,SWITZERLAND.

In addition, limited studies have been made of the rates of reaction of La3+, Eu3+, Dy3+, and Fe3+ with CLIII. The rate determining step in each system is an intramolecular process, the NpO2+-CLIII reaction proceeding by a first order approach to equilibrium in the acid range from 0.1 to 1.0 M. Complex formation occurs in a process independent of acidity, while both acid dependent and independent dissociation pathways are observed. The activation parameters for the complex formation reaction are Delta H* = 46.2(+/-0.3) kT mol(-1) and Delta S* = 7(+/-1) J mol(-1) K-1 (I = 1.0 M). The corresponding parameters for the acid dependent and independent dissociation pathways are Delta H* = 38.8(+/-0.6) kJ mol(-1), Delta S* = -96(+/-18) J mol(-1) K-1, Delta H*: = 70.0(+/-0.1) kJ mol(-1) and Delta S* = 17(+/-1) J mol(-1) K-1, respectively. An isokinetic relationship is observed between the activation parameters for CLIII complex formation with NpO2+, UO22+, Th4+, and Zr4+. The rates of CLIII complex formation reactions for Fe3+, Zr4+, NpO2+, UO22+, Th4+, La3+, Eu3+, and Dy3+ correlate with the cation radius rather than the charge/radius ratio.

Strontium is simply isolated by pulling an acidified sample aliquot through an Empore(TM) Strontium Rad Disk with a vacuum, and the disk is subsequently assayed for beta activity. The method is efficient, safe, reliable, and potentially field deployable. Sample preparation and counting source preparation may be condensed into a single procedure, thereby improving efficiency and eliminating many potential sources of laboratory error. Moreover, many of the hazardous chemicals associated with traditional strontium procedures are eliminated. Samples are easily batched, and a one-liter sample may be prepared with as little as 20 min of effort. For a one-liter aqueous sample, up to 3 mg of strontium can be retained by the disks. Chemical and radiometric interferences are discussed. C1 ARGONNE NATL LAB,DIV ENVIRONM RES,ARGONNE,IL 60439. 3M CO,ST PAUL,MN 55133. PACE INC,GOLDEN,CO 80403.

The Ingot event was fired above the static water level in bedded tuffs of the Nevada Test Site. Spectral gamma logging of the drill hole indicated a discrete zone of radioactivity at the depth of the working (firing) point. Subsequent radiochemical analysis confirmed the presence of Cs-137 and Sr-90. The short lived gaseous precursors of these species migrated through fractures created by the force of the explosion. Geophysical logging, radiochemical analysis and solids characterization at Ingot emphasize the significance of gaseous transport to radionuclide migration near sites of underground nuclear explosions.

Some historical perspective is given, but major emphasis is on recent studies. Isotopes of these elements are short-lived and, therefore, must be studied near the site of production. They must be produced with charged-particle beams at accelerators rather than via neutron capture. The use of radioactive heavy actinide targets is often required and the number of atoms produced is so small that any chemistry to be performed must be done on an ''atom-at-a-time'' basis. Furthermore, a knowledge of their nuclear properties is required in order to identify and detect them. To date, both gas and aqueous phase properties of elements as heavy as element 104 (rutherfordium) and element 105 (hahnium) have been investigated, even though their longest-lived known isotopes have half-lives of only 65 and 35 seconds, respectively. The experimental results show that their chemical properties cannot be simply extrapolated from the known properties of their lighter homologs in the periodic table, emphasizing the importance of obtaining additional experimental information for the heaviest elements to compare with predictions and help assess the influence of relativistic effects. The feasibility of the extension of chemical studies to still heavier elements is also discussed. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,DIV NUCL SCI,BERKELEY,CA 94720.

An extensive set of side wall samples were collected in these holes. We have analyzed the samples for tritium and for gamma-emitting radionuclides (both fission products and neutron activation products). It appears that the distribution pattern of these radioactive materials, established al the time of the detonation, have persisted even though the cavity has been under water for 13 years.

The technique, coupled with theoretical modeling of the processes occurring in the chromatography column, provides information about thermodynamic properties (e.g., adsorption enthalpies) for compounds of elements, such as the transactinides, which can only be produced on an atom-at-a-time basis. In addition, the chemical selectivity of the isothermal chromatography technique provides the decontamination from interfering activities necessary for determination of the nuclear decay properties of the isotopes of these elements. The Zr and Hf isotopes, 30.7-s Zr-98 and 38-s Hf-162 were produced via the U-235(n,f) and Sm-147(Ne-20,5n) reactions, respectively. The 65-s (261)Rf was produced via the Cm-248(O-18, 5n) reaction. A new and more accurate half-life for (261)Rf of 78(-6)(+11)-s has been measured. Measurements were performed on chloride species of Rf and its group 4 homologs, Zr and Hf and on Zr-bromides using the Heavy Element Volatility Instrument (HEVI). Adsorption enthalpies were calculated for all species using a Monte Carlo code simulation based on a microscopic model for gas thermochromatography in open columns with laminar flow of the carrier gas and the following adsorption enthalpies for the group 4 chlorides were obtained for quartz surfaces: Zr(-74+/-5 kJ/mol), Hf (-96+/-5 kJ/mol) and Rf (-77+/-6 kJ/mol). These results indicate that Rf deviates from the trend expected based on extrapolation of the Zr and Hf values. Further calculations are needed to assess whether this is due to relativistic effects in the transactinide region. C1 GT SEABORG INST TRANSACTINIUM SCI,LIVERMORE,CA.

Today much research is focused on development of a variety of boron compounds aimed for BNCT. The compounds must be thoroughly analysed in preclinical tests regarding basic characteristics such as binding and subcellular distribution to enable accurate estimations of dose-modifying factors. DAC-1, 2-[2-(3-amino-propyl)-1,2- dicarba-closo-dodecaboran(12)-1-yl-methoxy]-1,3-propanediol aas synthesized at our laboratories and the human colon carcinoma cells LS-174T were used as an in vitro Model. The boron compound showed a remarkable intracellular accumulation, 20-100 times higher than the boron content in the culture medium, in cultured cells and was not removed by extensive washes. Approximately half of the boron taken up also remained within the cells for at least 4 days. The DAC-1 compound alone was not toxic at boron concentrations below 2.5 mu g B/g. The intracellular distribution of he boron compound was investigated by subcellular fractionation experiments and low pH treatments. It is possible that DAC-1 binds to some intracellular molecules or to membranes connected with organelles in the cytoplasm or even to the inside of the outer cell membrane. Another possibility is that the compound, due to the somewhat lipophilic properties, is embedded in the membranes, Thermal neutron irradiations were carried out at the Brookhaven Medical Research Reactor (BMRR). At a survival level of 0.1, DAC-1 + thermal neutrons were about 10.5 limes more effective in cell inactivation than the thermal neutrons alone. Monte Carlo calculations gave a mean value of. the B-10-dependent specific energy, the dose, of 0.22 Gy, The total physical dose during irradiation of DAC-1-containing cells with a neutron fluence of 0.18 x 10(12) n/cm(2) was 0.39 Gy. The dose-modifying factor, at survival level 0.1, when comparing irradiation with thermal neutrons with and without DAC-1 was 3.4, while the dose-modifying factor when comparing neutron irradiations of cells with DAC-1 and irradiation of the cells with Co-60-gamma was 7.3. The results are encouraging and in vivo tests of tissue distributions and tumour uptake should now be carried out. C1 BROOKHAVEN NATL LAB,DEPT MED,UPTON,NY 11973.

Specifically, a 105 base-pair nucleotide portion of the ribosomal spacer region was amplified in two members of the B. cereus group (i.e. B. thuringiensis and B. cereus) using PCR. These amplified regions were then analyzed by gel electrophoresis and ESI-FTICR. Based on the predicted sequence of the PCR products for each organism, the mass measurement using ESI-FTICR matched the theoretical mass within experimental error and was consistent with gel electrophoresis results. In contrast, for the typical several hour time-scale of the gel electrophoresis experiment, the mass spectrometric analysis was completed in a matter of minutes. To our knowledge, this constitutes the first report demonstrating the ionization and detection of a double-stranded PCR product by ESI-MS. This preliminary result indicates the potential use of ESI-MS to analyze PCR products on a rapid time-scale, with potential for medical and taxonomic applications.

Ablated positive ions identified by time-of-flight mass spectrometry included Ba2+, F+, O+ and Ti+, each of which exhibited an intensity maximum near lambda=455.4 nm (2.72 eV), which corresponds to the Ba+ transition from the 6s S-2(1/2) ground state to the 6p P-2(3/2) excited state, The observed resonant Ba2+ yield enhancement suggests that some excited Ba-+* acquired sufficient additional energy from the ablation plasma to further ionize (IE{Ba+-->Ba2+}=10.00 eV), The simultaneous secondary enhancement in +1 ion yields for other elements suggests collisional energy transfer from Ba-+* to atomic or molecular plume species, exciting them to more easily ionized states, Although the detailed energy transfer mechanisms are indefinite, the general observations indicate that resonantly pumping energy into Ba+ heats the ablation plume with some species-selectivity, No significant wavelength-dependence was evident in the yields of BaX(+) from the gas-phase reactions of ablated Ba+ with C14F24 (X=F), CCl4 (X=Cl), Br-2 (X=Br), CH3I (X=I) and CH3OH (X=OH and OCH3), These observations reflect that the radiative lifetime of Ba-+* P-2(3/2) is only 6 ns, dictating that primarily ground state Ba+ encounter ambient reactants as the ablation plume expands.
