Air Force F-22 Fighter Program: Background and Issues for Congress

This report discusses the Air Force F-22 fighter, also known as the Raptor. The administration wants to end F-22 procurement at 187 aircraft, and the administration's proposed FY2010 budget does not request funding for the procurement of additional F-22s in FY2010. The issue of F-22 procurement has emerged as one of the highest-profile items of debate on the FY2010 defense budget. This report discusses both sides of the debate.

International Space Station: Significant Challenges May Limit Onboard Research (open access)

International Space Station: Significant Challenges May Limit Onboard Research

A letter report issued by the Government Accountability Office with an abstract that begins "In 2010, after about 25 years of work and the expenditure of billions of dollars, the International Space Station (ISS) will be completed. According to the National Aeronautics and Space Administration (NASA), the ISS crew will then be able to redirect its efforts from assembling the station to conducting research. In 2005, Congress designated the ISS as a national laboratory; in addition, the NASA Authorization Act of 2008 required NASA to provide a research management plan for the ISS National Laboratory. In light of these developments, the Government Accountability Office (GAO) was asked to review the research use of the ISS. Specifically, GAO (1) identified how the ISS is being used for research and how it is expected to be used once completed, (2) identified challenges to maximizing ISS research; and (3) identified common management practices at other national laboratories and large science programs that could be applicable to the management of the ISS. To accomplish this, GAO interviewed NASA officials and reviewed key documents related to the ISS. GAO also studied two ground-based national laboratories and several large science institutions."

On-Axis Brilliance and Power of In-Vacuum Undulators for the Advanced Photon Source. (open access)

On-Axis Brilliance and Power of In-Vacuum Undulators for the Advanced Photon Source.

A request for studying the spectral performance of in-vacuum undulators (IVUs) for the APS storage ring was recently put forward. In-vacuum undulators are prevalent at other synchrotron radiation facilities such as the ESRF and the Spring-8. However, they never made it into the arsenal of undulators at the APS because the brilliance tuning curves were sufficiently wide due to the fact that the undulator minimum gap could be set as low as 10.5 mm. For sector 3, which in the past used a narrow-gap vacuum chamber, the minimum undulator pole gap was allowed to be set as low as 8.5 mm, providing contiguous tuning curves between the first and third harmonic radiation for a 2.7-cm-period device. (Subsequently, the narrow-gap vacuum chamber was removed and replaced with a standard vacuum chamber, which allows a minimum gap of 10.5 mm.) For sector 4, which currently holds the only narrow-gap vacuum chamber at the APS, the minimum gap is 9.5 mm. In this sector, a permanent magnet hybrid undulator with SmCo magnets is used instead of NdFeB magnets because of their higher radiation resistance and their better protection against radiation-induced demagnetization of the magnets. In the realm of looking to the future, new …

Theoretical Description of the Fission Process (open access)

Theoretical Description of the Fission Process

Advanced theoretical methods and high-performance computers may finally unlock the secrets of nuclear fission, a fundamental nuclear decay that is of great relevance to society. In this work, we studied the phenomenon of spontaneous fission using the symmetry-unrestricted nuclear density functional theory (DFT). Our results show that many observed properties of fissioning nuclei can be explained in terms of pathways in multidimensional collective space corresponding to different geometries of fission products. From the calculated collective potential and collective mass, we estimated spontaneous fission half-lives, and good agreement with experimental data was found. We also predicted a new phenomenon of trimodal spontaneous fission for some transfermium isotopes. Our calculations demonstrate that fission barriers of excited superheavy nuclei vary rapidly with particle number, pointing to the importance of shell effects even at large excitation energies. The results are consistent with recent experiments where superheavy elements were created by bombarding an actinide target with 48-calcium; yet even at high excitation energies, sizable fission barriers remained. Not only does this reveal clues about the conditions for creating new elements, it also provides a wider context for understanding other types of fission. Understanding of the fission process is crucial for many areas of science and …

Characterization of Sediments from the Soil Desiccation Pilot Test (SDPT) Site in the BC Cribs and Trenches Area

This technical report documents the results of laboratory geochemical and hydrologic measurements of sediments collected from new borehole 299-E13-65 (C7047) and comparison of the results with those of nearby borehole 299-13E-62 (C5923) both drilled in the BC Cribs and Trenches Area. The total and water-leachable concentrations of key contaminants will be used to update contaminant-distribution conceptual models and to provide more data for improving baseline risk predictions and remedial alternative selections. Improved understanding of subsurface conditions and methods to remediate these principal contaminants can be also used to evaluate the application of specific technologies to other contaminants across the Hanford Site.

Enhanced Incluison Removal from Steel in the Tundish

The objective of this project was to develop an effective chemical filtering system for significantly reducing the content of inclusion particles in the steel melts exiting the tundish for continuous casting. This project combined a multi-process approach that aimed to make significant progress towards an "inclusion free" steel by incorporating several interdependent concepts to reduce the content of inclusions in the molten steel exiting the tundish for the caster. The goal is to produce "cleaner" steel.
