Joint Strike Fighter Acquisition: Mature Critical Technologies Needed to Reduce Risks

Description: A letter report issued by the General Accounting Office with an abstract that begins "The Joint Strike Fighter Program (JSFP), the military's most expensive aircraft program, is intended to produce affordable, next-generation aircraft to replace aging aircraft in military inventories. Although JSFP has made good progress in some technology areas, the program may not meet its affordability objective because critical technologies are not projected to be matured to levels GAO believes would indica… more

Chemical and Biological Defense: DOD Needs to Clarify Expectations in Medical Readiness

Description: A letter report issued by the General Accounting Office with an abstract that begins "Public assessments by Department of Defense (DOD) officials have emphasized the seriousness of the military threat from chemical and biological (CB) weapons. However, neither DOD nor the services have systematically examined the adequacy of the current specialty mix of medical personnel for CB defense. Although some of the services have begun to review the adequacy of staffing of deployable medical units that … more

Observations of the Behavior and Distribution of Fish in Relation to the Columbia River Navigation Channel and Channel Maintenance Activities

Description: This report is a compilation of 7 studies conducted for the U.S. Army Corps of Engineers between 1995 and 1998 which used hydroacoustic methods to study the behavior of migrating salmon in response to navigation channel maintenance activities in the lower Columbia River near river mile 45. Differences between daytime and nighttime behavior and fish densities were noted. Comparisons were made of fish distribution across the river (in the channel, channel margin or near shore) and fish depth upst… more

AN INVESTIGATION TO DOCUMENT MORROW RESERVOIRS THAT CAN BE BETTER DETECTED WITH SEISMIC SHEAR (S) WAVES THAN WITH COMPRESSIONAL (P) WAVES

Description: Pennsylvanian-age Morrow reservoirs are a key component of a large fluvial-deltaic system that extends across portions of Colorado, Kansas, Oklahoma, and Texas. A problem that operators have to solve in some Morrow plays in this multi-state area is that many of the fluvial channels within the Morrow interval are invisible to seismic compressional (P) waves. This P-wave imaging problem forces operators in such situations to site infill, field-extension, and exploration wells without the aid of 3… more

QBone University and Lab Interconnect Testbed (QUALIT). Final report

Description: The QUALIT grant funded two broad categories of work: (1) Project-wide QBone engineering, instrumentation, and integration; (2) Focused workshops and measurement work relating specifically to advanced university/DOE connectivity. Significant progress has been made in both areas and, to both, QUALIT funding has been a key enabling resource. This final report summarizes the accomplishments of the QUALIT project and explains changes to the technical focus of the project that, while significant, re… more

Internal Revenue Service: Progress Made, but Further Actions Needed to Improve Financial Management

Description: A letter report issued by the General Accounting Office with an abstract that begins "This is a follow-on to GAO's report on its audit of the Internal Revenue Service's (IRS) fiscal year 2000 financial statements. Many of the issues raised in this report have persisted for years. IRS believes that the solution to many of these issues may lie in systems modernization. IRS plans to implement a new financial system that includes a cost accounting module as well as integrated administrative and cus… more

National Ignition Facility (NIF) Control Network Design and Analysis

Description: The control network for the National Ignition Facility (NIF) is designed to meet the needs for common object request broker architecture (CORBA) inter-process communication, multicast video transport, device triggering, and general TCP/IP communication within the NIF facility. The network will interconnect approximately 650 systems, including the embedded controllers, front-end processors (FEPs), supervisory systems, and centralized servers involved in operation of the NIF. All systems are netw… more

History of the APS Topical Group on Shock Compression of Condensed Matter

Description: In order to provide broader scientific recognition and to advance the science of shock compressed condensed matter, a group of American Physical Society (APS) members worked within the Society to make this field an active part of the APS. Individual papers were presented at APS meetings starting in the 1940's and shock wave sessions were organized starting with the 1967 Pasadena meeting. Shock wave topical conferences began in 1979 in Pullman, WA. Signatures were obtained on a petition in 1984 … more

Oak Ridge 25URC Tandem Accelerator 2001 SNEAP Lab Report

Description: Radioactive ion beam production and development at the Holifield Radioactive Ion Beam Facility (HRIBF) will be detailed in a talk at this conference. A highlight during this period, however, has been providing A{approx}130 neutron-rich RIBs at energies up to {approx}4 MeV/nucleon. At the present time, the HRIBF is the only facility in the world capable of providing such beams.

Summary of Granulation Matrix Testing for the Plutonium Immobilization Program

Description: In FY00, a matrix for process development testing was created to identify those items related to the ceramic process that had not been fully developed or tested and to help identify variables that needed to be tested. This matrix, NMTP/IP-99-003, was jointly created between LLNL and SRTC and was issued to all affected individuals. The matrix was also used to gauge the progress of the development activities. As part of this matrix, several series of tests were identified for the granulation proc… more

Anisotropic flow at the SPS and RHIC

Description: The results on directed and elliptic flow for Pb + Pb at the full energy of the SPS (158 GeV/A) and from the first year of Au + Au at RHIC ({radical}s{sub NN} = 130 GeV) are reviewed. The different experiments agree well and a consistent picture has emerged indicating early time thermalization at RHIC.

Proton Emission from Gamow Resonance

Description: We demonstrated that it is possible to calculate the complex energy of the deformed Gamow state with a precision that is high enough so that the half-life calculated from the imaginary part of the energy is meaningful. We also performed a comparison between non-adiabatic and adiabatic calculations. It can be concluded that, in many cases, the corrected adiabatic treatment cannot be used as a substitute for the full non-adiabatic calculations.

Status of the Holifield Radioactive Ion Beam Facility

Description: The Holifield Radioactive Ion Beam Facility received authorization in December 1996 to commence routine operation as a National User Facility. Significant progress has been made toward the goal of providing high-quality radioactive ion beams. The task of producing radioactive ion beams of sufficient intensity to do research has required extensive research and development on target materials and ion-source design. During 1997-1998, our radioactive beam research and development program concentrat… more

Roof Integrated Solar Absorbers: The Measured Performance of ''Invisible'' Solar Collectors: Preprint

Description: The Florida Solar Energy Center (FSEC), with the support of the National Renewable Energy Laboratory, has investigated the thermal performance of solar absorbers that are an integral, yet indistinguishable, part of a building's roof. The first roof-integrated solar absorber (RISA) system was retrofitted into FSEC's Flexible Roof Facility in Cocoa, Florida, in September 1998. This ''proof-of-concept'' system uses the asphalt shingle roof surface and the plywood decking under the shingles as an u… more

Characterization of Stainless Steel and Refractory Metal Welds Made using a Diode-Pumped, Continuous Wave Nd: Yag Laser

Description: A series of laser welds have been made on several materials using a Rofin-Sinar DY-033, 3.3 kW, Diode-Pumped Continuous Wave (CW) Nd:YAG laser system, located at Los Alamos National Laboratory. Materials welded in these experiments include 21-6-9 stainless steel, 304L stainless steel, vanadium, and tantalum. The effects of changes in the power input at a constant travel speed on the depth, width, aspect ratio, and total melted area of the welds have been analyzed. Increases in the measured weld… more
