PVODE is a high-performance ordinary differential equation solver for the types of initial value problems (IVPs) that arise in large-scale computational simulations. often, one wants to compute sensitivities with respect to certain parameters in the IVP. They discuss the use of automatic differentiation (AD) to compute these sensitivities in the context of PVODE. Results on a simple test problem indicate that the use of AD-generated derivative code can reduce the time to solution over finite difference approximations.

Efforts to model and measure absolute neutron-induced reaction cross sections have for the most part been limited by experimental techniques to neutron energies found in reactors and light-ion fusion reactions (i.e., t(d,n){alpha} etc.). This can in large part be attributed to the difficulty involved in making high-flux mono-energetic neutron beams with E{sub n} > 14 MeV. The result has been a lack of guidance for (n,xnypz{alpha}) reaction modeling for E{sub n} > 1-2 MeV. These limitations become particularly exacerbated in nuclei where structure effects (i.e., near shell closures, high deformation etc.) or fission complicates the models. The GEANIE spectrometer at LANSCE/WNR fills this gap in experimental technique by allowing for efficient measurement of neutron-induced {gamma}-ray partial cross sections over a wide range of incident neutron energies (1 < E{sub n} (MeV) < 250). GEANIE consists of 20 Compton-suppressed and 6 unsuppressed hpGe detectors located at the 60{sup o} right beam line at the LANSCE/WNR spallation source. Eleven of the GEANIE detectors are Low Energy Planar Spectrometers (LEPS) with excellent timing and energy resolution. LANSCE/WNR provides a white source of neutrons through the spallation of a tungsten target with an 800 MeV 2-5 {micro}amp beam of protons. Neutron energy is determined …

This report describes the implementation of the Chaboche type Nonlinear Kinematic Hardening Model developed for the PNGV SPP (Partnership for the Next Generation Vehicle, Spring-back Predictability Project). The material model includes a nonlinear kinematic and isotropic hardening law, transverse anisotropy, strain range memorization for cyclic hardening/softening and viscoplasticity. This report is a companion to the report: ''A Return Mapping Algorithm for Cyclic Viscoplastic Constitutive Models'' which concentrates on the theoretical aspects of the model. This report summarizes the necessary parameters for the model, briefly discusses their interpretation and shows some numerical simulations. The report also specifies the data structure requirements for linking the material model software by explicitly referencing the source code delivered to the SPP collaborators.

Traditional induction tools use source arrays in which both receiving and transmitting magnetic dipoles are oriented along the borehole axis. This orientation has been preferred for traditional isotropic formation evaluation in vertical boreholes because borehole effects are minimized by the source-receiver-borehole symmetry. However, this source-receiver geometry tends to minimize the response of potentially interesting geological features? such as bed resistivity anisotropy and fracturing which parallels the borehole. Traditional uniaxial tool responses are also ambiguous in highly deviated boreholes in horizontally layered formations. Resolution of these features would be enhanced by incorporating one or more source transmitters that are perpendicular to the borehole axis. Although these transmitters can introduce borehole effects, resistive oil-based muds minimize borehole effects for horizontal source data collection and interpretation. However, the use of oil based muds is contraindicated in environmentally sensitive areas. For this reason, it is important to be able to assess the influence of conductive water based muds on the new generation of triaxial induction tools directed toward geothermal resource evaluation and to develop means of ameliorating any deleterious effects. The present paper investigates the effects of a borehole on triaxial measurements. The literature contains a great deal of work on analytic expressions for …

A glass-choice strategy, based on separately designing an achromatic lens before progressing to an apochromatic lens, simplified my approach to solving the International Optical Design Conference (IODC) 1998 lens design problem. The glasses that are needed to make the lens apochromatic are combined into triplet correctors with two ''buried'' surfaces. By applying this strategy, I reached successful solutions that used only six glasses--three glasses for the achromatic design and three additional glasses for the apochromatic design.

We have built a two-stage adiabatic demagnetization refrigerator (ADR) to operate cryogenic high-resolution x-ray detectors in synchrotron-based fluorescence applications. The detector is held at the end of a 40 cm cold finger that extends into a UHV sample chamber. The ADR attains a base temperature below 100 mK with about 24 hours hold time below 400 mK, and does not require pumping on the liquid He bath. We will discuss cryostat design and performance.

The Stockpile Stewardship Program is an initiative to maintain the nuclear deterrent of the United States in the post-Cold War era. It is based on the maintenance of our stockpile through an ongoing process of surveillance, assessment, refurbishment, and recertification, without nuclear testing. At the heart of the SSP is an attempt to bring advanced experimental and computational tools to bear on the evaluation and certification of the stockpile itself; these advanced scientific capabilities are necessary because of the cessation of nuclear testing. This science-based approach requires new tools: advanced computers for more detailed 3-D simulations, multi-axis hydrodynamic facilities and plutonium research facilities for physics measurements of primaries, and the National Ignition Facility for fusion burn and high-energy-density science. The science basis requires summing up the pieces we can measure and simulate, which cannot be done without a complete set of tools. Refurbishing weapons with confidence, without testing, is a difficult challenge. Only with high-quality scientists and a complete set of tools, can the US accomplish this program. NIF is a unique element of the Stockpile Stewardship Program because it is the only facility that will allow the experimental study of thermonuclear burn and important regimes of high-energy-density science. Understanding …

The National Ignition Facility (NIF) will have many uses besides its primary mission in the US Department of Energy's Stockpile Stewardship Program. It will provide a broad array of applications to basic science, and will also play an important role in the development of commercial fusion energy.
