Pulsed, Inductively Generated, Streaming Plasma Ion Source for Heavy Ion Fusion Linacs
This report describes a compact, high current density, pulsed ion source, based on electrodeless, inductively driven gas breakdown, developed to meet the requirements on normalized emittance, current density, uniformity and pulse duration for an ion injector in a heavy-ion fusion driver. The plasma source produces >10 μs pulse of Argon plasma with ion current densities >100 mA/cm2 at 30 cm from the source and with strongly axially directed ion energy of about 80 eV, and sub-eV transverse temperature. The source has good reproducibility and spatial uniformity. Control of the current density during the pulse has been demonstrated with a novel modulator coil method which allows attenuation of the ion current density without significantly affecting the beam quality. This project was carried out in two phases. Phase 1 used source configurations adapted from light ion sources to demonstrate the feasibility of the concept. In Phase 2 the performance of the source was enhanced and quantified in greater detail, a modulator for controlling the pulse shape was developed, and experiments were conducted with the ions accelerated to >40 kV.

Rental Housing Assistance: Policy Decisions and Market Factors Explain Changes in the Costs of the Section 8 Programs
A letter report issued by the Government Accountability Office with an abstract that begins "Annual appropriations for the Department of Housing and Urban Development's (HUD) Section 8 programs--a key federal tool for subsidizing rents of low-income households--have increased sharply in recent years, raising concerns about their cost. Section 8 pays the difference between a unit's rent and the household's payment (generally 30 percent of adjusted income). Section 8 includes a voucher program administered by public housing agencies (PHA) that allows eligible households to use vouchers to rent units in the private market and a project-based program administered by property owners who receive subsidies to rent specific units to eligible households. In both programs, contracts between HUD and the administrators specify the duration and amount of the subsidy. GAO assessed Section 8 trends from fiscal years 1998 through 2004 and examined (1) annual budget authority and outlays for each program; (2) factors that have affected outlays; and (3) the estimated impact of factors, such as market rents, on the average rental subsidy per voucher household."

Social Security Administration: Additional Actions Needed to Prevent Improper Benefit Payments under Social Security Protection Act
A letter report issued by the Government Accountability Office with an abstract that begins "Continued high levels of unauthorized immigrant workers in the United States have fostered concerns about whether they should be eligible for Social Security benefits. Until recently, the Social Security Administration (SSA) allowed noncitizens to collect benefits, regardless of their work authorization status, provided that they met certain legal presence requirements. However, in March 2004, Congress passed the Social Security Protection Act, which under Section 211, requires that noncitizens assigned a Social Security number (SSN) after 2003 have work authorization from current or past qualifying work to collect benefits. This report describes (1) the steps SSA has taken to implement Section 211 and how effective SSA's policies and procedures are in preventing improper benefit decisions, and (2) how Section 211 has affected the payment of benefits to unauthorized workers."

TOXECON RETROFIT FOR MERCURY AND MULTI-POLLUTANT CONTROL ON THREE 90-MW COAL-FIRED BOILERS
With the Nation's coal-burning utilities facing tighter controls on mercury pollutants, the U.S. Department of Energy is supporting projects that could offer power plant operators better ways to reduce these emissions at much lower costs. Sorbent injection technology represents one of the simplest and most mature approaches to controlling mercury emissions from coal-fired boilers. It involves injecting a solid material such as powdered activated carbon into the flue gas. The gas-phase mercury in the flue gas contacts the sorbent and attaches to its surface. The sorbent with the mercury attached is then collected by a particulate control device along with the other solid material, primarily fly ash. We Energies has over 3,200 MW of coal-fired generating capacity and supports an integrated multi-emission control strategy for SO{sub 2}, NO{sub x}, and mercury emissions while maintaining a varied fuel mix for electric supply. The primary goal of this project is to reduce mercury emissions from three 90-MW units that burn Powder River Basin coal at the We Energies Presque Isle Power Plant. Additional goals are to reduce nitrogen oxide (NO{sub x}), sulfur dioxide (SO{sub 2}), and particulate matter (PM) emissions, allow for reuse and sale of fly ash, demonstrate a reliable mercury …

Urinary Metabolites of the Dietary Carcinogen PhIP are Predictive of Colon DNA Adducts After a Low Dose Exposure in Humans
Epidemiologic evidence indicates that exposure to heterocyclic amines (HAs) in the diet is an important risk factor for the development of colon cancer. Well-done cooked meats contain significant levels of HAs which have been shown to cause cancer in laboratory animals. To better understand the mechanisms of HA bioactivation in humans, the most mass abundant HA, 2-amino-l-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), was used to assess the relationship between PhIP metabolism and DNA adduct formation. Ten human volunteers were administered a dietary relevant dose of [{sup 14}C]PhIP 48-72 h prior to surgery to remove colon tumors. Urine was collected for 24 h after dosing for metabolite analysis, and DNA was extracted from colon tissue and analyzed by accelerator mass spectrometry for DNA adducts. All ten subjects were phenotyped for CYP1A2, NAT2, and SULT1A1 enzyme activity. Twelve PhIP metabolites were detected in the urine samples. The most abundant metabolite in all volunteers was N-hydroxy-PhIP-N{sup 2}-glucuronide. Metabolite levels varied significantly between the volunteers. Interindividual differences in colon DNA adducts levels were observed between each individual. The data showed that individuals with a rapid CYP1A2 phenotype and high levels of urinary N-hydroxy-PhIP-N{sup 2}-glucuronide, had the lowest level of colon PhIP-DNA adducts. This suggests that glucuronidation plays a …

VA Health Care: Experiences in Denver and Charleston Offer Lessons for Future Partnerships with Medical Affiliates
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Veterans Affairs (VA) maintains affiliations with medical schools, including the Medical University of South Carolina (MUSC) and the University of Colorado at Denver and Health Services Center and University of Colorado Hospital (UCH), to obtain enhanced medical care for veterans. As part of their plans for new medical campuses, both UCH and MUSC proposed jointly constructing and operating new medical facilities with VA in Denver and Charleston, respectively. This report discusses (1) how VA evaluated the joint venture proposals for Denver and Charleston and the status of these proposals, (2) the challenges these proposals pose for VA, and (3) the lessons VA can learn from its experiences in Charleston and Denver for future partnerships."

Absolute Measurement of Electron Cloud Density in a Positively-Charged Particle Beam
Clouds of stray electrons are ubiquitous in particle accelerators and frequently limit the performance of storage rings. Earlier measurements of electron energy distribution and flux to the walls provided only a relative electron cloud density. We have measured electron accumulation using ions expelled by the beam. The ion energy distribution maps the depressed beam potential and gives the dynamic cloud density. Clearing electrode current reveals the static background cloud density, allowing the first absolute measurement of the time-dependent electron cloud density during the beam pulse.

BaBar Silicon Vertex Tracker: Status and Prospects
The BABAR Silicon Vertex Tracker (SVT) has been efficiently operated for six years since the start of data taking in 1999. Due to higher than expected background levels some unforeseen effects have appeared. We discuss: a shift in the pedestal for the channels of the AToM readout chips that are most exposed to radiation; an anomalous increase in the bias leakage current for the modules in the outer layers. Estimates of future radiation doses and occupancies are shown together with the extrapolated detector performance and lifetime, in light of the new observations.
