Responding to a need to include realistic chemistry and ionization in the driven plasmas in plasma-aided manufacture, we became convinced that existing computational tools were not able to fulfill our requirements. In response to this, we invented an entirely new approach to such problems. Our approach is to generalize the capabilities of existing methods: Particle-In-Cell (PIC) contains the required details of the distributions but becomes overwhelming expensive when applied to realistic, multidimensional problems. The common alternative, the hydrodynamic model, has simply lost the ability to model this science because of the simple fluid assumption. Our solution, GAPH (for Grid and Particle Hydrodynamics), retains the kinetic capabilities of PIC while using fluid concepts within each particle to control the incredible expense. The coupling of these two methods has resulted in a very powerful new algorithm that is now being applied to a range of programmatic problems throughout LLNL that now far outstrips the initial applications area.

A CRADA with Kevex Instruments was carried out to develop improved XRMF instrumentation for the nondestructive analysis of electronic components during manufacture. Experiments conducted at Y-12 proved the feasibility of a new Kevex x-ray tube design. Tests also show that the current commercial supply of straight glass capillaries is unreliable; however, other vendors of tapered single and multiple glass capillaries were identified. The stability of the Y-12 x-ray microprobe was significantly enhanced as a result of this CRADA.

Low-frequency electromagnetic simulation models have a wide range of industrial applications. We have built several models, differentiated by slightly different physics approximations or computational solution methods, that have proven quite useful in a variety of applications. Our models been used to investigate beam plasma interactions in ICF targets, antenna plasma coupling in plasma processing, and magnetic implosion drive in Z-pinch pulsed power generators. The common feature of these models is that they retain inductive effects but implicitly ignore computationally intensive, fully electromagnetic effects. However, the preponderance of our work has been limited to only two dimensions. We have made significant progress modeling low-frequency electromagnetic physics with a new model in 2-D that is now capable of modeling antenna structures in 3-D. Although LLNL`s interest in plasma processing has diminished, we have certainly added to LLNL`s capabilities. Interestingly, we have already found another application, the magnetic behavior of read/write heads in the magnetic storage industry, that can make use of many of the computational methods described here, rewarding us again for maintaining a strong core competency in low-frequency EM plasmas.

There has been an accelerating national interest in countering nuclear smuggling. This has caused a corresponding expansion of interest in the use of gamma-ray spectrometers for checkpoint monitoring, nuclear search, and within networks of nuclear and collateral sensors. All of these are fieldable instruments--ranging from large, fixed portal monitors to hand-held and remote monitoring equipment. For operational reasons, detectors with widely varying energy resolution and detection efficiency will be employed. In many instances, such instruments must be sensitive to weak signals, always capable of recognizing the gamma-ray signatures from nuclear weapons materials (NWM), often largely insensitive to spectral alteration by radiation transport through intervening materials, capable of real-time implementation, and able to discriminate against signals from commonly encountered legitimate gamma-ray sources, such as radiopharmaceuticals. Several decades of experience in classified programs have shown that all of these properties are not easily achieved and successful approaches were of limited scope--such as the detection of plutonium only. This project was originally planned as a two-year LDRD-ER. Since funding for 1997 was not sustained, this is a report of the first year's progress.

A letter from James Hutchens to R. William McCarter about the upcoming National Curriculum Working Group meeting and the new project of developing three art education curriculum units.

This report documents activities carried in support of the design and construction of an ultra-high precision measuring machine intended for the support of Extreme Ultraviolet Lithography development (for semiconductor fabrication). At the outset, this project was aimed at the overall fabrication of such a measuring machine. Shortly after initiation, however, the scope of activities was reduced and effort was concentrated on the key technical advances necessary to support such machine development: high accuracy surface sensing and highly linear distance interferometry.
