Broadband diffractive lens
Significant progress has been made toward solving the century-old problem of chromatic aberrations in diffractive optics. Our approach exploits modern materials and microfabrication technology and is very different from the purely diffractive strategy,'' which is commonly employed and which results in multiple diffractive elements separated by a finite distance. We have developed a Fresnel zone plate lens comprised of a serial stack of patterned minus-filters which allows broadband radiation to be focused (or imaged) without longitudinal or transverse chromatic aberrations. 7 refs., 4 figs.

Studies of the Formation of Field Reversed Plasma by a Magnetized Co-Axial Plasma Gun
The gun injects axially into a drift tank followed by a magnetic mirror. For the experiments reported here, only the guide coils outside the vacuum vessel and solenoids on the plasma gun electrodes were used; the mirror coil was not energized. A stainless steel flux conserver is placed in the mirror throat to prevent the plasma from contacting the nonconducting vacuum wall in the region of the mirror. An axis encircling array of magnetic loop probes includes four diamagnetic loops and a loop which measures the azimuthally averaged outward pointing radial component of magnetic field. These loop probes are stainless steel jacketed and form a flux conserving boundary (at a radius = 30 cm) for plasma emitted from the gun. A five tip probe that can be positioned anywhere along the axis of the experiment is used to measure internal components of magnetic field.

Photogenerated carrier-induced reactions on uhv semiconductor surfaces
The objective for this experimental work was to examine the reaction mechanisms, half-collision dynamics, and other optically induced chemical effects, that are operable on a well characterized single-crystal semiconductor surface. Of particular interest were reactions induced by charge transfer from the semiconductor surface including hot carrier and thermalized carrier processes. The primary technique to measure the desorbed fragment translational energies was time-of-flight mass-spectroscopy, used in conjunction with a pulsed tunable laser source. The work was carried out in ultrahigh vacuum, thus other surface spectroscopies such as temperature-programmed desorption, (TPD), (LEED), etc. were used as needed. In the project, the photoreactions of several halogen-containing molecules on GaAs(110) surfaces have been investigated. The studies have made the first observations of several new photochemical processes on uhv prepared surfaces including intermolecular charge transfer; desorption by thermal-carrier-induced reactions (including the measurement of coverage-dependent changes in the translational energies of the desorbed products); interferometric oscillation of photoinduced reactions; and self-quenching of thermal carrier reactions on surfaces.

Transportation Security Administration: High-Level Attention Needed to Strengthen Acquisition Function
A letter report issued by the General Accounting Office with an abstract that begins "The Transportation Security Administration (TSA), within the Department of Homeland Security, was established to secure the nation's transportation systems, beginning with commercial airports. To meet its mission, TSA has awarded over $8.5 billion in contracts since its creation in 2001. Spending on contracts accounted for 48 percent of TSA's fiscal year 2003 budget. Because of TSA's reliance on contracts to carry out its mission, its acquisition infrastructure-- including oversight, policies and processes, acquisition workforce, and information about its acquisitions--is critical. GAO was asked to review TSA's acquisition infrastructure to assess how well TSA is positioned to carry out its acquisition function."

Nuclear Regulation: NRC's Liability Insurance Requirements for Nuclear Power Plants Owned by Limited Liability Companies
A letter report issued by the General Accounting Office with an abstract that begins "An accident at one the nation's commercial nuclear power plants could result in human health and environmental damages. To ensure that funds would be available to settle liability claims in such cases, the Price-Anderson Act requires licensees for these plants to have primary insurance--currently $300 million per site. The act also requires secondary coverage in the form of retrospective premiums to be contributed by all licensees to cover claims that exceed primary insurance. If these premiums are needed, each licensee's payments are limited to $10 million per year and $95.8 million in total for each of its plants. In recent years, limited liability companies have increasingly become licensees of nuclear power plants, raising concerns about whether these companies--by shielding their parent corporations' assets--will have the financial resources to pay their retrospective premiums. GAO was asked to determine (1) the extent to which limited liability companies are the licensees for U.S. commercial nuclear power plants, (2) the Nuclear Regulatory Commission's (NRC) requirements and procedures for ensuring that licensees of nuclear power plants comply with the Price-Anderson Act's liability requirements, and (3) whether and how these procedures differ …

Spectrum Management: Better Knowledge Needed to Take Advantage of Technologies That May Improve Spectrum Efficiency
A letter report issued by the General Accounting Office with an abstract that begins "Recent advances in technologies that rely on the use of the radiofrequency spectrum have turned science fiction of the past into reality. Cellular telephones, wireless computer networks, global positioning system receivers, and other spectrum-dependent technologies are quickly becoming as common to everyday life as radios and televisions. Further, these technologies have become critical to a variety of government missions, including homeland security and strategic warfare. However, with the increased demand, the radio-frequency spectrum--a resource that once seemed unlimited--has become crowded and, in the future, may no longer be able to accommodate all users' needs. As a result, there has been a growing debate among spectrum policy leaders about how to use spectrum more efficiently. To help inform these debates, GAO was asked to look at agencies' investments in spectrum efficient technologies and how the nation's spectrum management system may affect the development and adoption of these technologies."

Temporary Assistance for Needy Families: Implications of Recent Legislative and Economic Changes for State Programs and Work Participation Rates
A letter report issued by the Government Accountability Office with an abstract that begins "The Deficit Reduction Act of 2005 (DRA) reauthorized the Temporary Assistance for Needy Families (TANF) block grant and made modifications expected to strengthen work requirements for families receiving cash assistance through state TANF programs. Both the U.S. Department of Health and Human Services (HHS) and states were required to take steps to implement these changes. Work participation rates, or the proportion of families receiving TANF cash assistance that participated in work activities, are the key performance measure HHS uses to assess state TANF programs. In response to the economic recession that began in 2007, the American Recovery and Reinvestment Act of 2009 (Recovery Act), provided additional TANF funding to eligible states and made additional modifications to TANF. GAO examined (1) How did DRA affect state TANF programs, including work participation rates? (2) How has the recent economic recession affected state TANF programs? (3) How did the Recovery Act affect state TANF programs? To address these questions, GAO analyzed federal TANF data, as well as relevant federal laws, regulations, and guidance; interviewed HHS officials; surveyed all state TANF administrators; and conducted site visits to meet with state …

File Sharing: Selected Universities Report Taking Action to Reduce Copyright Infringement
A letter report issued by the General Accounting Office with an abstract that begins "The emergence of peer-to-peer file-sharing applications that allow networks to share computer files among millions of users has changed the way copyrighted materials, including digital music, videos, software, and images can be distributed and has led to a dramatic increase in the incidence of copyright infringement (piracy) of these digital materials. These applications enable direct communication between users, allowing users to access each other's files and share digital music, videos, and software. According to a coalition of intellectual property owners in the entertainment industry, an increasing number of students are using the fast Internet connections offered by college and university networks to infringe copyrights by illegally downloading and sharing massive volumes of copyrighted materials on peer-to-peer networks. GAO was asked to describe (1) the views of major universities on the extent of problems experienced with student use of file-sharing applications as well as the actions that the universities are taking to deal with them and (2) the actions that federal enforcement agencies have taken to address the issue of copyright infringement on peer-to-peer networks as well as agency views on any legislative barriers to dealing with …

U.S. Attorneys: Performance-Based Initiatives are Evolving
A letter report issued by the General Accounting Office with an abstract that begins "Within the Department of Justice (DOJ), the 94 U.S. Attorneys Offices represent the United States in criminal and civil matters across the nation. The Government Performance and Results Act (GPRA) of 1993 requires federal agencies, including DOJ, to set goals and objectives, measure performance, and report their accomplishments in order to move toward a performance-based environment. Integral to achieving these goals and objectives is strategic human capital management--the marshalling, managing, and maintaining the human capital needed to maximize government performance and achieve accountability. This report describes (1) how DOJ's strategic goals and objectives apply to U.S. Attorneys, (2) DOJ's plans and efforts to develop performance measures that apply to U.S. Attorneys, (3) the processes DOJ uses for monitoring the performance of U.S. Attorneys Offices, and (4) DOJ efforts to move toward strategic human capital management for U.S. Attorneys Offices."

Energy Employees Compensation: Even with Needed Improvements in Case Processing, Program Structure May Result in Inconsistent Benefit Outcomes
A letter report issued by the General Accounting Office with an abstract that begins "Subtitle D of the Energy Employees Occupational Illness Compensation Program Act of 2000 allows the Department of Energy (Energy) to help its contractors' employees file state workers' compensation claims for illnesses determined by a panel of physicians to be caused by exposure to toxic substances while employed at an Energy facility. This report examines the effectiveness of the benefit program under Subtitle D and focuses on four key areas: (1) the number, status, and characteristics of claims filed with Energy; (2) the extent to which Energy policies and procedures help employees file timely claims for these state benefits; (3) the extent to which there will be a "willing payer" of workers' compensation benefits, that is, an insurer that--by order from or agreement with Energy--will not contest these claims; and (4) a framework that could be used for evaluating possible options for changing the program."

NASA: Lack of Disciplined Cost-Estimating Processes Hinders Effective Program Management
A letter report issued by the General Accounting Office with an abstract that begins "For more than a decade, GAO has identified the National Aeronautics and Space Administration's (NASA) contract management as a high-risk area--in part because of NASA's inability to collect, maintain, and report the full cost of its programs and projects. Lacking this information, NASA has been challenged to manage its programs and control program costs. The scientific and technical expectations inherent in NASA's mission create even greater challenges--especially if meeting those expectations requires NASA to reallocate funding from existing programs to support proposed new efforts. Because cost growth has been a persistent problem in a number of NASA programs, GAO was asked to examine NASA's cost estimating for selected programs, assess NASA's cost-estimating processes and methodologies, and describe any barriers to improving NASA's cost-estimating processes. To conduct GAO's work, GAO analyzed a total of 27 NASA programs--10 of which GAO reviewed in detail."

Cigarette Smuggling: Federal Law Enforcement Efforts and Seizures Increasing
A letter report issued by the General Accounting Office with an abstract that begins "Illegal trafficking in cigarettes can generate enormous profits and is purportedly a multibillion dollar a year enterprise. As cigarette taxes increase, so do the incentives for criminal organizations to smuggle cigarettes into the United States. Cigarette smuggling results in lost tax revenues, undermines government health policy objectives, can attract sophisticated and organized criminal groups, and could be a source of funding for terrorists. Because of these concerns, GAO examined (1) the nature and scope of the problem of smuggled cigarettes entering the United States, including federal tax revenue losses and potential health risks; (2) federal law enforcement agencies'--U.S. Immigration and Customs Enforcement (ICE), U.S. Customs and Border Protection (CBP), and Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF)--efforts to thwart the smuggling of cigarettes into the United States; and (3) legal initiatives being pursued to enhance law enforcement efforts to thwart the smuggling of cigarettes into the United States."

Financial Audit: Federal Deposit Insurance Corporation Funds' 2008 and 2007 Financial Statements
A letter report issued by the Government Accountability Office with an abstract that begins "GAO is required to annually audit the financial statements of the Deposit Insurance Fund (DIF) and FSLIC Resolution Fund (FRF), which are administered by the Federal Deposit Insurance Corporation (FDIC). GAO is responsible for obtaining reasonable assurance about whether FDIC's financial statements for DIF and FRF are presented fairly in all material respects, in conformity with U.S. generally accepted accounting principles, and whether FDIC maintained effective internal control over financial reporting and compliance with laws and regulations. Also, GAO is responsible for testing FDIC's compliance with selected laws and regulations. Created in 1933 to insure bank deposits and promote sound banking practices, FDIC plays an important role in maintaining public confidence in the nation's financial system. In 1989, legislation to reform the federal deposit insurance system created three funds to be administered by FDIC: the Bank Insurance Fund (BIF) and the Savings Association Insurance Fund (SAIF), which protect bank and savings deposits, and FRF, which was created to close out the business of the former Federal Savings and Loan Insurance Corporation. In accordance with subsequent legislation passed in 2006, FDIC merged the BIF and SAIF into …
