Parallel algorithm for transient solid dynamics simulations using finite elements and smoothed particle hydrodynamics
An efficient, scalable, parallel algorithm for treating contacts in solid mechanics has been applied to interactions between particles in smooth particle hydrodynamics (SPH). The algorithm uses three different decompositions within a single timestep: (1) a static FE-decomposition of mesh elements; (2) a dynamic SPH-decomposition of SPH particles; (3) and a dynamic contact-decomposition of contact nodes and SPH particles. The overhead cost of such a scheme is the cost of moving mesh and particle data between the decompositions. This cost turns out to be small in practice, leading to a highly load-balanced decomposition in which to perform each of the three major computational states within a timestep.

Reaction cross-section calculations using new experimental and theoretical level structure data for deformed nuclei
A technique for modeling level structures of odd-odd nuclei has been used to construct sets of discrete states with energies in the range 0 to 1.5 MeV for several nuclei in the rare-earth and actinide regions. The accuracy of the modeling technique was determined by comparison with experimental data. Examination was made of what effect the use of these new, more complete sets of discrete states has on the calculation of level densities, total reaction cross sections, and isomer ratios. 9 refs.

Optical assessment of large marine particles: development of an imaging and analysis sytem for quantifying large particle distributions and fluxes. Annual report, 1992-1993
The central goal of DOE`s Ocean Margin Program (OMP) is to determine whether continental shelves are quantitatively significant in removing carbon dioxide from the atmosphere and isolating it via burial in sediments or exporting it to the open ocean (Program Announcement, 1991). A major component of the OMP will be to measure carbon flux on the shelf and across the shelf to the slope and open ocean. We are developing a video and optical instrument package (LAPS: Large Aggregate Profiling System) and the analytical techniques to precisely measure a wide spectrum of the large aggregate population of particles in the shelf/slope environment. This particle population, encompassing the ``marine snow`` size particles (diameters > 0.5 mm), is thought to be the major pathway of material flux in the ocean (McCave, 1975; Asper, 1987; Walsh and Gardner, 1992). Our goal is to use aggregate abundance and size spectrum data along with the CTD, beam attenuation and fluorescence data collected with our instrument package to collect data rapidly, repeatedly and accurately such that it is both linkable to carbon flux and usable in biophysical models. Additionally, measurements of particle flux will be made with sediment traps deployed on the continental slope in conjunction …

Charm production physics from Fermilab fixed-target experiments
Recent analyses of charm quark production mechanisms from Fermilab fixed-target experiments are summarized. Measurements of single inclusive differential cross sections for hadroproduced and photoproduced D mesons are compared to next-to-leading order QCD calculations. New data from hadroproduction and previous photoproduction measurements of charm meson pair correlations are compared to NLO calculations and also to parton shower Monte Carlo models. Nonperturbative effects, such as intrinsic k{sub t} and fragmentation, are seen to play an important role in most of these comparisons. Results on charm production asymmetries in both hadroproduction and photoproduction are summarized.

Proton Capture Gamma Rays From Si$Sup 28$ in the Region of the Photonuclear Giant Resonance
The Livermore 90 deg inch variable-energy cyclotron was used to measure the 90 deg excitation function for the Al/sup 27/(p, gamma )Si/sup 28/ reaction. Proton energies between 5 and 13 Mev were used which gave excitation energies in Si/sup 28/ corresponding to the region of the photonuclear giant resonance. Two gamma rays were observed: gamma /sub O/, the groundstate gamma ray and gamma / sub 1/ resulting from deexcitation through the first excited state of Si/sup 28/ at 1.78 Mev. They were detected by a 5-in.-diam by 6-in.-long NaI(Tl) crystal. A Pb collimator was used to improve the resolution of the detector. The results indicated that both gamma /sub O/ and gamma /sub 1/ display the giant resonance behavior; the gamma /sub O/ carve reached a peak value of approximately -8 mu barns/sr at E/sub p/ = 8.75 Mev, while the gamma /sub 1/ peak was approximately -14 mu barns/sr at E/sub p/ = 10 Mev. Both curves displayed the fine structure previously reported by Gove et al. A detailed balance calculation was made, using the gamma /sub O/ data. A comparison with the measurements of Johansson on the total yield of protons from the Si/sup 28/( gamma ,p)Al reaction …

Deep Ultrasound Enhancements Final Report
This study involves collaboration between Los Alamos National Laboratory and Lawrence Livermore National Laboratory to enhance and optimize LANL's ultrasonic inspection capabilities for production. Deep-penetrating ultrasonic testing enhancement studies will extend the current capabilities, which only look for disbonds. Current ultrasonic methods in production use 15-20 MHz to inspect for disbonds. The enhanced capabilities use 5 MHz to penetrate to the back surface and image the back surface for any flaws. The enhanced capabilities for back surface inspection use transducers and squirter modifications that can be incorporated into the existing production system. In a production setup the current 15-20 MHz transducer and squirter would perform a bond inspection, followed by a deep inspection that would be performed by simply swapping out the 5 MHz transducer and squirter. Surrogate samples were manufactured of beryllium and bismuth to perform the ultrasonic enhancement studies. The samples were used to simulate flaws on the back surface and study ultrasound's ability to image them. The ultrasonic technique was optimized by performing experiments with these samples and analyzing transducer performance in detecting flaws in the surrogate. Beam patterns were also studied experimentally using a steel ball reflector to measure beam patterns, focal points, and sensitivities to …

Development of a process control sensor for the glass industry
This project was initiated to fill a need in the glass industry for a non-contact temperature sensor for glass melts. At present, the glass forming industry (e.g., bottle manufacture) consumes significant amounts of energy. Careful control of temperature at the point the bottle is molded is necessary to prevent the bottle from being rejected as out-of-specification. In general, the entire glass melting and conditioning process is designed to minimize this rejection rate, maximize throughput and thus control energy and production costs. This program focuses on the design, development and testing of an advanced optically based pyrometer for glass melts. The pyrometer operates simultaneously at four wavelengths; through analytical treatment of the signals, internal temperature profiles within the glass melt can be resolved. A novel multiplexer alloys optical signals from a large number of fiber-optic sensors to be collected and resolved by a single detector at a location remote from the process. This results in a significant cost savings on a per measurement point basis. The development program is divided into two phases. Phase 1 involves the construction of a breadboard version on the instrument and its testing on a pilot-scale furnace. In Phase 2, a prototype analyzer will be constructed …

Thin film porous membranes based on sol-gel chemistry for catalytic sensors
Nanoporous sol-gel based films are finding a wide variety of uses including gas separations and supports for heterogeneous catalysts. The films can be formed by spin or dip coating, followed by relatively low temperature annealing. The authors used several types of these films as coatings on the Pd alloy thin film sensors they had previously fabricated and studied. The sol-gel films have little effect on the sensing response to H{sub 2} alone. However, in the presence of other gases, the nanoporous film modifies the sensor behavior in several beneficial ways. (1) They have shown that the sol-gel coated sensors were only slightly poisoned by high concentrations of H{sub 2}S while uncoated sensors showed moderate to severe poisoning effects. (2) For a given partial pressure of H{sub 2}, the signal from the sensor is modified by the presence of O{sub 2} and other oxidizing gases.

Contamination surveys for release of material
This report describes, and presents the technical basis for, a methodology for performing instrument surveys to release material from radiological control, including release to controlled areas and release from radiological control. The methodology is based on a fast scan survey, a large-area wipe survey, and a series of statistical, fixed measurements. The methodology meets the requirements of the US Department of Energy Radiological Control Manual (RadCon Manual) (DOE 1994) and DOE Order 5400.5 (DOE 1990) for release of material in less time than is required by a conventional scan survey. Implementation of the proposed methodology with a confidence interval of 67% will meet the material release requirements. The material evaluation process will allow material that has not been exposed to contamination to be released from radiological control without a survey. For potential radioactive contaminants that are not reserved in DOE Order 5400.5, the methodology will allow material to be released from radiological control. For other radionuclides, with the exception of some difficult-to-detect radionuclides, material may be released for controlled use. Compared with current techniques, the proposed methodology will reduce the amount of time required to perform surveys.

Gravel admix, vegetation, and soil water interactions in protective barriers: Experimental design, construction, and initial conditions
The purpose of this study is to measure the interactive effects of gravel admix and greater precipitation on soil water storage and plant abundance. The study is one of many tasks in the Protective Barrier Development Program for the disposal of Hanford defense waste. A factorial field-plot experiment was set up at the site selected as the borrow area for barrier topsoil. Gravel admix, vegetation, and enhanced precipitation treatments were randomly assigned to the plots using a split-split plot design structure. Changes in soil water storage and plant cover were monitored using neutron probe and point intercept methods, respectively. The first-year results suggest that water extraction by plants will offset gravel-caused increases in soil water storage. Near-surface soil water contents were much lower in graveled plots with plants than in nongraveled plots without plants. Large inherent variability in deep soil water storage masked any effects gravel may have had on water content below the root zone. In the future, this source of variation will be removed by differencing monthly data series and testing for changes in soil water storage. Tests of the effects of greater precipitation on soil water storage were inconclusive. A telling test will be possible in the …
