Effect of the electrostatic plasma lens on the emittance of ahigh-current heavy ion beam
We describe measurements we have made of the emittance of a high-current, moderate-energy ion beam after transport through a permanent-magnet electrostatic plasma lens. The results indicate the absence of emittance growth due to the lens, when the lens is adjusted for optimal beam focusing. The measured emittance for a 16 keV Cu{sup 2+} ion beam formed by a vacuum arc ion source was about 0.4 {pi} {center_dot} mm {center_dot} mrad at a beam current of 50 mA rising more-or-less linearly to 1.5 {pi} {center_dot} mm {center_dot} mrad at 250 mA, and was conserved in beam transport through the lens. These results have significance for the application of high-current ion sources and the electrostatic plasma lens to particle accelerator injection.

MICROSTRUCTURAL FEATURES AFFECTING PROPERTIES AND AGING OF TRITIUM-EXPOSED AUSTENTIC STAINLESS STEEL
A project to implement a life-cycle engineering approach to tritium reservoirs has been initiated through the DOE - Technology Investment Projects. The first task in the project was to develop a comprehensive list of microstructural features that impact the aging performance of the tritium reservoirs. Each of the participating sites (SRNL, SNL, LANL, KCP) independently developed a list of features deemed integral to tritium reservoir performance based upon operational and design experience. An integrated list of features was ultimately developed by the project team that could be included in the modeling process. The features of interest were chosen based upon their impact on the following key factors in controlling crack growth: (1) the H/He solubility or diffusivity within the materials, (2) the stress/strain state at the crack tip, (3) material threshold for crack extension, and (4) microstructure based fracture distance, commonly estimated by grain size for intergranular fracture. Wherever possible, key references were identified to substantiate the effects on the tritium embrittlement phenomenon of the various microstructural features. Each of these features was chosen based upon their impact to the cracking phenomenon of interest. The features chosen were typically associated with orientation, morphology, and distribution of phases and inclusions, grain …

Adaptations of the Purge Water Management System for Long-Term Groundwater Monitoring at Savannah River Site, South Carolina (final)
To monitor the groundwater contamination and the effectiveness of remedial actions, over a thousand monitoring wells are in active operation (i.e., require quarterly or semi-annual sampling) at SRS. Most wells are expected to continue in operation for another 20 to 40 more years. Required sample volumes can range from a less than a liter to 10 liters. To support the long-term groundwater monitoring requirements of these wells, SRS actively seeks technologies that can maximize data acquisition and minimize costs. To meet this end, SRS has implemented the Purge Water Management System (PWMS). The key attributes of this system lie in its ability to reduce or eliminate the generation of purged groundwater, which is costly in terms of the time and management.

Developing an energy efficiency service industry in Shanghai
The rapid development of the Chinese economy over the past two decades has led to significant growth in China's energy consumption and greenhouse gas (GHG) emissions. Between 1980 and 2000, China's energy consumption more than doubled from 602 million to 1.3 billion tons of coal-equivalent (NBS, 2003). In 2000, China's GHG emissions were about 12% of the global total, ranked second behind only the US. According to the latest national development plan issued by the Chinese government, China's energy demand is likely to double again by 2020 (DRC, 2004), based on a quadrupling of its gross domestic product (GDP). The objectives of the national development plan imply that China needs to significantly raise the energy efficiency of its economy, i.e., cutting the energy intensity of its economy by half. Such goals are extremely ambitious, but not infeasible. China has achieved such reductions in the past, and its current overall level of energy efficiency remains far behind those observed in other developed economies. However, challenges remain whether China can put together an appropriate policy framework and the institutions needed to improve the energy efficiency of its economy under a more market-based economy today. Shanghai, located at the heart of the Yangtze …

Double-shell target design for the NIF: Noncryogenic ignition and nonlinear mix studies for Stockpile Stewardship
Double-shell ignition is complementary to the baseline approach by virtue of not requiring: (1) cryogenic preparation and fielding, (2) high-contrast pulse-shaping for shock-timing, and (3) demanding x-ray flux symmetry control. The use of simpler low-contrast pulse-shaping potentially allows more benign hohlraum conditions by reducing the risk of laser backscatter. In addition, the associated higher laser fluence threshold for optics damage initiation allows the possibility of more routine high-fluence shots with 2{omega} on the NIF. Based on LDRD-sponsored research in FY01-03 on NIF double-shell ignition target designs, the feasibility of this approach was advanced through both a highly successful implosion campaign on the Omega laser facility and a variety of design improvements for mitigating instability. The double-shell implosion campaign on Omega achieved the important milestone of repeatably demonstrating dominant primary (2.45 MeV) neutron production from the mix-susceptible compressional phase of a double-shell implosion, using fall-line design optimization and exacting fabrication standards. Showing effective control of fuel-pusher mix during final compression is an essential element for achieving ignition. In our studies to control mix by reducing hydrodynamic instability a new pathway for destructive Rayleigh-Taylor growth on the outer surface of the inner shell at ignition scales was identified. However, highly resolved multi-mode …

Government-Sponsored Enterprises: A Framework for Strengthening GSE Governance and Oversight
Testimony issued by the General Accounting Office with an abstract that begins "Congress established government sponsored enterprises (GSE)-- such as Fannie Mae, Freddie Mac, the FHLBank System, and the Farm Credit System--to facilitate the development of mortgage and agricultural lending in the United States. Although the federal government does not explicitly guarantee the GSEs' approximately $4.4 trillion in financial obligations, the potential exists that the government would provide financial assistance in an emergency as it has done in the past. Recent financial reporting problems at Freddie Mac have raised concerns about the quality of the GSEs' corporate governance and regulatory oversight. To assist Congress in reviewing the adequacy of GSE oversight, this testimony provides information on GSE corporate governance, regulatory oversight, and mission compliance measures."

Guidelines - A Primer for Communicating Effectively with NABIR Stakeholders
This version of the communication primer comprises two interlocking parts: Pat 1, a practical section, intended to prepare you for public interactions, and Part 2, a theoretical section that provides social and technical bases for the practices recommended in Part 1. The mutual support of practice and theory is very familiar in science and clearly requires a willingness to observe and revise our prior assumptions--in this document, we invoke both. We hope that is offering will represent a step both towards improving practice and maturing the theory of practical science communication.

Heterogeneity of Sedimentary Aquifers: effect on microbial dynamics at successive spatial scales as revealed by geophysical imaging: Final report to the Department of Energy on Award DE-FG02-9ER62478
This report describes the geological component of the interdisciplinary study of the experimental aquifer at Oyster, Virginia, by the NABIR program, Department of Energy (Natural and Accelerated Bioremediation Research), between 1997 and 2003, as conducted by the Sediment dynamics group of Old Dominion University. The Geological component of the Oyster study was designed to (1) predict patterns of physical heterogeneity in sedimentary aquifers that control groundwater flow by application of geological first principles, (2) determine the geophysical imaging signatures of these patterns, and (3) relate patterns of physical heterogeneity thus sampled to observed microbial populations. The geological study began in 1997 at the North Oyster site, but in 2002, moved to the South Oyster site.

HHS Bioterrorism Preparedness Programs: States Reported Progress but Fell Short of Program Goals for 2002
Correspondence issued by the General Accounting Office with an abstract that begins "The anthrax incidents during the fall of 2001 raised concerns about the nation's ability to respond to bioterrorist events and other public health threats. The incidents strained the public health system, including surveillance and laboratory workforce capacities, at the state and local levels. Several months after the incidents, the Congress appropriated funds to strengthen state and local bioterrorism preparedness. The Department of Health and Human Services' (HHS) Centers for Disease Control and Prevention (CDC) and Health Resources and Services Administration (HRSA) distributed the funds in 2002 through two cooperative agreement programs with state, municipal, and territorial governments. To strengthen preparedness, the two cooperative agreement programs--CDC's Public Health Preparedness and Response for Bioterrorism Program and HRSA's National Bioterrorism Hospital Preparedness Program--require participants to complete specific activities designed to build public health and health care capacities. The 2002 cooperative agreements for both programs ended on August 30, 2003. For the 2002 cooperative agreements, CDC's and HRSA's programs distributed approximately $918 million and approximately $125 million, respectively. The Public Health Security and Bioterrorism Preparedness and Response Act of 2002 directs us to report on federal programs that support preparedness efforts at …

Information Technology: OMB and Department of Homeland Security Investment Reviews
A letter report issued by the General Accounting Office with an abstract that begins "In July 2002, the Office of Management and Budget (OMB) issued two memorandums directing agencies expected to be part of the Department of Homeland Security (DHS) to temporarily cease funding for new information technology (IT) infrastructure and business systems investments and submit information to OMB on current or planned investments in these areas. GAO was asked to (1) explain OMB's implementation of these memorandums, (2) identify any resulting changes to applicable IT investments, and (3) ascertain if DHS has initiated its own investment management reviews and, if so, what the results of these reviews have been."

LDRD LW Project Final Report:Resolving the Earthquake Source Scaling Problem
The scaling behavior of basic earthquake source parameters such as the energy release per unit area of fault slip, quantitatively measured as the apparent stress, is currently in dispute. There are compelling studies that show apparent stress is constant over a wide range of moments (e.g. Choy and Boatwright, 1995; McGarr, 1999; Ide and Beroza, 2001, Ide et al. 2003). Other equally compelling studies find the apparent stress increases with moment (e.g. Kanamori et al., 1993; Abercrombie, 1995; Mayeda and Walter, 1996; Izutani and Kanamori, 2001; Richardson and Jordan, 2002). The resolution of this issue is complicated by the difficulty of accurately accounting for attenuation, radiation inhomogeneities, bandwidth and determining the seismic energy radiated by earthquakes over a wide range of event sizes in a consistent manner. As one part of our LDRD project we convened a one-day workshop on July 24, 2003 in Livermore to review the current state of knowledge on this topic and discuss possible methods of resolution with many of the world's foremost experts.

Measuring the Effect of Fuel Structures and Blend Distribution on Diesel Emissions Using Isotope Tracing
Carbon atoms occupying specific positions within fuel molecules can be labeled and followed in emissions. Renewable bio-derived fuels possess a natural uniform carbon-14 ({sup 14}C) tracer several orders of magnitude above petroleum-derived fuels. These fuels can be used to specify sources of carbon in particulate matter (PM) or other emissions. Differences in emissions from variations in the distribution of a fuel component within a blend can also be measured. Using Accelerator Mass Spectrometry (AMS), we traced fuel components with biological {sup 14}C/C levels of 1 part in 10{sup 12} against a {sup 14}C-free petroleum background in PM and CO{sub 2}. Different carbon atoms in the ester structure of the diesel oxygenate dibutyl maleate displayed far different propensities to produce PM. Homogeneous cosolvent and heterogeneous emulsified ethanol-in-diesel blends produced significantly different PM despite having the same oxygen content in the fuel. Emulsified blends produced PM with significantly more volatile species. Although ethanol-derived carbon was less likely to produce PM than diesel fuel, it formed non-volatile structures when it resided in PM. The contribution of lubrication oil to PM was determined by measuring an isotopic difference between 100% bio-diesel and the PM it produced. Data produced by the experiments provides validation for …
