Adaptive optics enables high resolution imaging through the atmospheric by correcting for the turbulent air's aberrations to the light waves passing through it. The Lawrence Livermore National Laboratory for a number of years has been at the forefront of applying adaptive optics technology to astronomy on the world's largest astronomical telescopes, in particular at the Keck 10-meter telescope on Mauna Kea, Hawaii. The technology includes the development of high-speed electrically driven deformable mirrors, high-speed low-noise CCD sensors, and real-time wavefront reconstruction and control hardware. Adaptive optics finds applications in many other areas where light beams pass through aberrating media and must be corrected to maintain diffraction-limited performance. We describe systems and results in astronomy, medicine (vision science), and horizontal path imaging, all active programs in our group.

The objectives of the mini airlift bubbler testing are to evaluate the impact of the bubbler on melt rate, melting behavior and cold cap structure, foam formation and stability, bubbler air venting, off gas behavior, and electrode/plenum power use. In addition, the effects of frit and plenum temperature on bubbler performance were evaluated. This report will cover the second program element, the evaluation of two lengths of mini-bubblers in Slurry Fed Melt Rate Furnaces to assess melting behavior and melt rate enhancement.

Aluminum corrosion and turbidity formation in reactors correlate with fuel sheath temperature. To further substantiate this correlation, discharged fuel elements from R-3, P-2 and K-2 cycles were examined for extent of corrosion and evidence of breaking off of the oxide film.

Detailed residual stress analysis was performed for a multi-pass butt weld, representing the middle butt-girth weld of a storage tank. The analysis procedures took into account representative welding parameters, joint detail, weld pass deposition sequence, as well as temperature-dependent properties. The predicted residual stresses were then considered in stress intensity factor calculations using a three-dimensional finite element alternating model for investigating crack growth behavior for both small elliptical surface and through-wall cracks.

This report provides information on the Office of Management and Budget’s (OMB) Circular A-76, “Performance of Commercial Activities,” and the impact of a related reform initiative, the Federal Activities Inventory Reform Act (FAIR) of 1998, within the Department of Defense. The Circular defines federal policy for determining whether recurring commercial activities should be outsourced to commercial sources, Governmental facilities, or through inter-service support agreements. The FAIR Act creates statutory reporting requirements for federal executive agencies, by requiring Federal executive agencies to identify activities “not inherently governmental” and consider outsourcing through managed competitions. However, FAIR does not require that agencies contract out these activities.

Congress supports the research and development efforts of the Department of Defense (DOD) with a Research, Development, Test and Evaluation (RDT&E) appropriation. The appropriation primarily supports the development of the nation’s future military hardware and software and the technology base upon which those products rely. It is the federal government’s single largest research and development account. Besides supporting the nation’s military needs, some of the technology developed with RDT&E funds spills over into the commercial sector. For these reasons, RDT&E funding draws a considerable amount of attention within Congress each year.

The reflectance stability of multilayer coatings for extreme ultraviolet lithography (EUVL) in a commercial tool environment is of uttermost importance to ensure continuous exposures with minimum maintenance cost. We have made substantial progress in designing the protective capping layer coatings, understanding their performance and estimating their lifetimes based on accelerated electron beam and EUV exposure studies. Our current capping layer coatings have about 40 times longer lifetimes than Si-capped multilayer optics. Nevertheless, the lifetime of current Ru-capped multilayers is too short to satisfy commercial tool requirements and further improvements are essential.

X-ray Photoelectron Diffraction (XPD) is a well established technique for probing element and site specific surface structure of epitaxial thin films and nanostructures. Furthermore, recent studies have demonstrated that excitation of the photoelectrons via circularly polarized photons results in additional sensitivity to the element and site specific local magnetic order via the dipole selection rules. However the asymmetries involved in such experiments are very low, typically 1-2%. Calculations suggest that combining excitation via circularly polarized photons with spin polarized photoelectron detection into a complete ''double polarization'' experiment should lead to a 5-10 fold increase in asymmetry. However combining high angular resolution XPD with spin resolving capability poses significant experimental challenges. A new compact angle resolving spin spectrometer for conducting such double polarization experiments has recently been developed at the Advanced Light Source by the authors. This spectrometer combines a large (11 inch) diameter fixed hemispherical analyzer with a novel rotatable input lens system allowing data with {+-}1 degree angular resolution to be acquired for any combination of incident and emission angles, including normal incidence/normal emission (figure 1). The analyzer is equipped with both multichannel detection for high resolution (50meV) spin integrated spectroscopies, such as XPS and magnetic linear or circular …

Digital television (DTV) is a new television service representing the most significant development in television technology since the advent of color television in the 1950s. DTV can provide sharper pictures, a wider screen, CD-quality sound, better color rendition, and other new services currently being developed. A successful deployment of DTV requires: the development by content providers of compelling digital programming; the delivery of digital signals to consumers by broadcast television stations, as well as cable and satellite television systems; and the widespread purchase and adoption by consumers of digital television equipment. A key issue in the Congressional debate over the digital transition has been addressing the millions of American over-the-air households whose existing analog televisions will require converter boxes in order to receive digital signals when the analog signal is turned off.

This report provides an overview of District of Columbia-related policy and funding issues of interest to Congress. The United States Constitution gives Congress exclusive legislative authority over the affairs of the District of Columbia. As a result, the 108th Congress may debate a number of funding, governance, and constitutional issues affecting the District of Columbia, including approval of the city’s budget, enactment of a general federal payment, budget autonomy for the city, and voting representation in Congress. In addition, Congress will consider whether to continue to include in the District’s appropriations bills for FY2003 and FY2004, a number of controversial general provisions that District officials claim infringe on the principles of home rule.

The purpose of this study was to investigate the economic appropriateness of several enhanced oil recovery processes that are available to a small mature oil field located in southwest Arkansas and to implement the most economic efficient process evaluated. The State of Arkansas natural resource laws require that an oilfield is to be unitized before conducting a secondary recovery project. This requires all properties that can reasonably be determined to include the oil productive reservoir must be bound together as one common lease by a legal contract that must be approved to be fair and equitable to all property owners within the proposed unit area.
