The Next Generation Light Source (NGLS) is a high repetition rate free-electron laser facility proposed by Lawrence Berkeley National Laboratory (LBNL). The proposed facility will provide multiple FEL lines with varying spectral characteristics to satisfy a broad soft X-ray physics programme. At this stage of the project a number of FEL technologies and concepts are being investigated for possible implementation on the facility. In this report we consider a free-electron laser seeded by a Higher Harmonic Generation (HHG) source in which a high power (and consequently relatively low repetition rate) laser pulse is injected into a chamber of inert gas. Through a process of ionisation and recombination coherent higher harmonics of the laser are emitted from the gas and can be injected into an FEL system as a seed field. Further harmonic upconversion can be done within the FEL system to enable temporally coherent FEL output at wavelengths much shorter than, and pulse energies orders of magnitude higher than, the HHG source emission. The harmonic conversion within the FEL works in the following way. The seed field induces an energy modulation within the electron bunch at the start of the modulator. This energy modulation grows within the modulator due to …

Between May 2009 and August 2010, arrests were made for 19 "homegrown," jihadist-inspired terrorist plots by American citizens or legal permanent residents of the United States. The apparent spike in such activity after May 2009 suggests that at least some Americans - even if a tiny minority - continue to be susceptible to ideologies supporting a violent form of jihad. This report describes homegrown violent jihadists and the plots and attacks that have occurred since 9/11. This report also provides official definitions for terms such as "homegrown," "jihadist," and "violent jihadist." The report also discusses the radicalization process and the forces driving violent extremist activity. It analyzes post-9/11 domestic jihadist terrorism, describes law enforcement and intelligence efforts to combat terrorism and the challenges associated with those efforts. It also outlines actions underway to build trust and partnership between community groups and government agencies and the tensions that may occur between law enforcement and engagement activities.

Ultrafast nanocrystallography has the potential to revolutionize biology by enabling structural elucidation of proteins for which it is possible to grow crystals with 10 or fewer unit cells. The success of nanocrystallography depends on robust orientation-determination procedures that allow us to average diffraction data from multiple nanocrystals to produce a 3D diffraction data volume with a high signal-to-noise ratio. Such a 3D diffraction volume can then be phased using standard crystallographic techniques."Indexing" algorithms used in crystallography enable orientation determination of a diffraction data from a single crystal when a relatively large number of reflections are recorded. Here we show that it is possible to obtain the exact lattice geometry from a smaller number of measurements than standard approaches using a basis pursuit solver.

This report will examine logistical support contracts for troop support services (also known as service contracts) in Iraq and Afghanistan, primarily administered through a smaller program, the United States Air Force Contract Augmentation Program (AFCAP) and a larger program, the United States Army's Logistics Civil Augmentation Program (LOGCAP). This report will focus primarily on contracts involving Department of Defense (DOD) appropriated funds, although some projects involve a blending of funds from other agencies.

A study has confirmed the feasibility of designing, fabricating and installing resonant magnetic field perturbation (RMP) coils in JET1 with the objective of controlling edge localized modes (ELM). A system of two rows of in-vessel coils, above the machine midplane, has been chosen as it not only can investigate the physics of and achieve the empirical criteria for ELM suppression, but also permits variation of the spectra allowing for comparison with other experiments. These coils present several engineering challenges. Conditions in JET necessitate the installation of these coils via remote handling, which will impose weight, dimensional and logistical limitations. And while the encased coils are designed to be conventionally wound and bonded, they will not have the usual benefit of active cooling. Accordingly, coil temperatures are expected to reach 350 C during bakeout as well as during plasma operations. These elevated temperatures are beyond the safe operating limits of conventional OFHC copper and the epoxies that bond and insulate the turns of typical coils. This has necessitated the use of an alternative copper alloy conductor C18150 (CuCrZr). More importantly, an alternative to epoxy had to be found. An R&D program was initiated to find the best available insulating and bonding …

Policy makers and program designers in the U.S. and abroad are deeply concerned with the question of how to scale up energy efficiency to a level that is commensurate both to the scale of the energy and climate challenges we face, and to the potential for energy savings that has been touted for decades. When policy makers ask what energy efficiency can do, the answers usually revolve around the technical and economic potential of energy efficiency - they rarely hone in on the element of energy demand that matters most for changing energy usage in existing homes: the consumer. A growing literature is concerned with the behavioral underpinnings of energy consumption. We examine a narrower, related subject: How can millions of Americans be persuaded to divert valued time and resources into upgrading their homes to eliminate energy waste, avoid high utility bills, and spur the economy? With hundreds of millions of public dollars flowing into incentives, workforce training, and other initiatives to support comprehensive home energy improvements, it makes sense to review the history of these programs and begin gleaning best practices for encouraging comprehensive home energy improvements. Looking across 30 years of energy efficiency programs that targeted the residential …

Spectral reflectance was used to determine the thickness of thin glue layers in a study of the effect of the glue on radiance and reflectance measurements of shocked-tin substrates attached to lithium fluoride windows. Measurements based on profilometry of the components were found to be inaccurate due to flatness variations and deformation of the tin substrate under pressure during the gluing process. The accuracy of the spectral reflectance measurements were estimated to be ±0.5 μm, which was sufficient to demonstrate a convincing correlation between glue thickness and shock-generated light.

The developers of the Paharpur Business Center (PBC) and Software Technology Incubator Park in New Delhi, India offer an environmentally sustainable building with a strong emphasis on energy conservation, waste minimization and superior indoor air quality (IAQ). To achieve the IAQ goal, the building utilizes a series of air cleaning technologies for treating the air entering the building. These technologies include an initial water wash followed by ultraviolet light treatment and biolfiltration using a greenhouse located on the roof and numerous plants distributed throughout the building. Even with the extensive treatment of makeup air and room air in the PBC, a recent study found that the concentrations of common volatile organic compounds and aldehydes appear to rise incrementally as the air passes through the building from the supply to the exhaust. This finding highlights the need to consider the minimization of chemical sources in buildings in combination with the use of advanced air cleaning technologies when seeking to achieve superior IAQ. The goal of this project was to identify potential source materials for indoor chemicals in the PBC. Samples of building materials, including wood paneling (polished and unpolished), drywall, and plastic from a hydroponic drum that was part of the …

Correspondence issued by the Government Accountability Office with an abstract that begins "In August and September 2009, Humana--a large private health insurer--sent a letter to the approximately 930,000 beneficiaries enrolled in its Medicare Advantage (MA) plans, advising that leading health reform proposals could adversely affect MA beneficiaries. Signed by Humana's Chief Medical Officer, the letter stated that if proposed funding cuts became law, "millions of seniors and disabled individuals could lose many of the important benefits and services that make MA health plans so valuable," and encouraged beneficiaries to contact their members of Congress and ask them to protect MA funding. Once the Centers for Medicare & Medicaid Services (CMS) learned about the mailing, the agency directed Humana on September 18, 2009, and all other MA organizations on September 21, 2009, to immediately stop all communications to beneficiaries about the potential impact of health reform legislation while CMS investigated whether such communications violated federal laws, regulations, or MA program guidance. CMS issued clarifying guidance to all MA organizations on October 16, 2009, and took compliance action against some organizations, closing its investigation. CMS is responsible for overseeing communications between MA organizations and beneficiaries enrolled in their plans. Because MA organizations …

A letter report issued by the Government Accountability Office with an abstract that begins "The United States uses arms transfers through government-to-government Foreign Military Sales (FMS) and direct commercial sales (DCS) to support its foreign policy and national security goals. The Departments of Defense (DOD) and State (State) have authorized arms worth billions of dollars to six Persian Gulf countries: Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates (UAE). The United States established the Gulf Security Dialogue (GSD) to discuss security issues with these countries. GAO was asked to determine (1) the dollar value and nature of U.S. arms transfers authorized for the Gulf countries' governments, (2) the extent to which U.S. agencies documented how arms transfers to Gulf countries advanced U.S. foreign policy and national security goals, and (3) the role of the GSD. To conduct this work, GAO analyzed U.S. government regional plans, arms transfer data from fiscal years 2005 to 2009, case-specific documentation for fiscal years 2008 and 2009, and program guidance; and interviewed officials in Bahrain, Saudi Arabia, and the UAE."

A letter report issued by the Government Accountability Office with an abstract that begins "The President's Emergency Plan for AIDS Relief (PEPFAR), reauthorized at $48 billion for fiscal years 2009 through 2013, supports HIV/AIDS prevention, treatment, and care services overseas. The reauthorizing legislation, as well as other key documents and PEPFAR guidance, endorses the alignment of PEPFAR activities with partner country HIV/AIDS strategies and the promotion of partner country ownership of U.S.-supported HIV/AIDS programs. This report, responding to a legislative directive, (1) examines alignment of PEPFAR programs with partner countries' HIV/AIDS strategies and (2) describes several challenges related to alignment or promotion of country ownership. GAO analyzed PEPFAR planning documents and national strategies for four countries--Cambodia, Malawi, Uganda, and Vietnam--selected to represent factors such as diversity of funding levels and geographic location. GAO also reviewed documents and reports by the U.S. government, research institutions, and international organizations and interviewed PEPFAR officials and other stakeholders in headquarters and the four countries."

These jurisdictions are estimated to receive about two-thirds of the intergovernmental assistance available through the Recovery Act. This report also responds to GAO's mandate to comment on the jobs estimated in recipient reports. GAO collected and analyzed documents and interviewed state and local officials and other Recovery Act award recipients. GAO also analyzed federal agency guidance and interviewed federal officials."

Other written product issued by the Government Accountability Office with an abstract that begins "This supplementary report to GAO-10-999 provides individual state appendixes for 16 states and the District of Columbia for GAO's work on the seventh of its bimonthly reviews of the American Recovery and Reinvestment Act (Recovery Act)."

Correspondence issued by the Government Accountability Office with an abstract that begins "In February 2009, Congress created two new programs as part of the American Recovery and Reinvestment Act of 2009 (Recovery Act): (1) the Tax Credit Assistance Program (TCAP) administered by the Department of Housing and Urban Development (HUD) and (2) the Grants to States for Low-Income Housing Projects in Lieu of Low-inome Housing Credits Program under Section 1602 of the Recovery Act (Section 1602 Program) administered by the Department of the Treasury (Treasury). Congress created these new programs to address the lack of private investment capital in Low-Income Housing Tax Credit (LIHTC) projects after the credit market was disrupted in 2008. Both programs were intended to provide gap financing for stalled, "shovel-ready" projects and to offset a drop in tax credit demand and pricing. Under these programs, state Housing Finance Agencies (HFA) administer federal funds in the form of grants and loans from HUD and Treasury to fill financing gaps in planned tax credit projects."
