Radiation sources and diagnostics with ultrashort electron bunches (open access)

Radiation sources and diagnostics with ultrashort electron bunches

The basic principles and design of radiation sources (transition radiation, Cerenkov radiation, radiation from periodic structures, etc.) and radiation-based diagnostics will be discussed, with emphasis on radiation from ultra-short electron bunches. Ultra-short electron bunches have the potential to produce high peak flux radiation sources that cover wavelength regimes where sources are currently not widely available (coherent THz/IR) as well as ultrashort X-ray pulses (3-100 fs). While radiation from the electron bunch contains the full signature of the electron beam and/or medium it has travelled through, the deconvolution of a single property of interest can be difficult due to a large number of contributing properties. The experimental implementation of novel solutions to this problem will be described for beams from 30 MeV to 30 GeV, including fluctuational interferometry, source imaging, phase matched cone angles and laser-based techniques, which utilize optical transition radiation, wiggler and Cerenkov radiation, and Thomson scattering. These novel diagnostic methods have the potential to resolve fs bunch durations, slice emittance on fs scales, etc. The advantages and novel features of these techniques will be discussed.

Military Transformation: Navy Efforts Should Be More Integrated and Focused (open access)

Military Transformation: Navy Efforts Should Be More Integrated and Focused

A letter report issued by the General Accounting Office with an abstract that begins "With the end of the Cold War, national security strategies changed to meet new global challenges. The Navy developed a new strategic direction in the early 1990s, shifting its primary focus from open ocean "blue water" operations to littoral, or shallow water, operations closer to shore. GAO found that although the Navy has recently placed more emphasis on transformation, it does not have a well-defined and overarching strategy for transformation. It has not clearly identified the scope and direction of its transformation; the overall goals, objectives, and milestones; or the specific strategies and resources to be used in achieving these goals. It also has not clearly identified organizational roles and responsibilities, priorities, resources, or ways to measure progress. Without a well-defined strategic plan to guide the Navy's efforts, senior leaders and Congress will not have the tools they need to ensure that the transformation is successful."

Indian Issues: Improvements Needed in Tribal Recognition Process (open access)

Indian Issues: Improvements Needed in Tribal Recognition Process

A letter report issued by the General Accounting Office with an abstract that begins "The Indian gambling industry has flourished since the enactment of the Indian Gaming Regulatory Act in 1988. Nearly 200 tribes generated about $10 billion in annual revenues in 1999 from their gambling operations. Because of weaknesses in the federal recognition process, the basis for tribal recognition decisions by the Bureau of Indian Affairs (BIA) is not always clear and the length of time involved can be substantial. Despite an increasing workload, the number of BIA staff assigned to evaluate the petitions has fallen by about 35 percent since 1993. Just as important, the process lacks effective procedures for promptly addressing the increased workload. In particular, the process does not impose effective deadlines that create a sense of urgency, and procedures for providing information to interested third parties are ineffective. GAO summarized this report in testimony before Congress; see: Indian Issues: More Consistent and Timely Tribal Recognition Process Needed, by Barry T. Hill, Director for Natural Resources and Environment, before the Subcommittee on Energy Policy, Natural Resources and Regulatory Affairs, House Committee on Government Reform. GAO-01-415T, Feb. 7 (nine pages)."

Means-Tested Programs: Determining Financial Eligibility Is Cumbersome and Can Be Simplified (open access)

Means-Tested Programs: Determining Financial Eligibility Is Cumbersome and Can Be Simplified

A letter report issued by the General Accounting Office with an abstract that begins "About 80 means-tested federal programs assisted low-income people in 1998. GAO reviewed 11 programs that assisted families and individuals with income, food, medical assistance, and housing. Despite substantial overlap in the populations they serve, the 11 programs varied significantly in their financial eligibility rules. At the most basic level, the dollar levels of the income limits--the maximum amounts of income an applicant can have and still be eligible for a program--vary across programs. Beyond this, differences exist in the income rules, such as whose income and what types of income are counted. The variations and complexity of the federal financial eligibility rules, along with other factors, have led to processes that are often duplicative and cumbersome for both caseworkers and applicants. Overall, federal, state, and local entities have made little progress in simplifying or coordinating eligibility determination processes. States realigned some of the financial rules, but only to a limited extent. Another approach uses computer systems to establish joint eligibility determination processes that a single caseworker can administer. Efforts to simplify or better coordinate eligibility determination processes confront many obstacles, including restrictive federal program statutes and …
