A 3-dimensional theory of free electron lasers

Description: In this paper, we present an analytical three-dimensional theory of free electron lasers. Under several assumptions, we arrive at an integral equation similar to earlier work carried out by Ching, Kim and Xie, but using a formulation better suited for the initial value problem of Coherent Electron Cooling. We use this model in later papers to obtain analytical results for gain guiding, as well as to develop a complete model of Coherent Electron Cooling.

222-S Analytical services final results for Tank 241-U-101, grab samples 1U-96-1 through 1U-96-4

Description: This document is the final, format IV, laboratory report for characterization of tank 241-U-101 (U-101) grab samples from risers 1 and 7. It transmits additional analytical data for specific gravity (Sp.G.), and all raw analytical data which were not provided in the 45-day report. The 45-day report is attached to this final report as Part II. Secondary analyses were not performed on any of the U-101 samples. This is because none of the primary analyte limits, which trigger the performance of se… more

2004 Annual Meeting - Genes, Mutations and Disease: The Environmental Connection

Description: The Meeting consisted of 9 Symposia, 4 Keynote Lectures, 3 Platform Sessions and 4 Poster Sessions. In addition there were Breakfast Meetings for Special Interest Groups designed to inform attendees about the latest advances in environmental mutagenesis research. Several of the topics to be covered at this broad meeting will be of interest to the Department of Energy, Office of Science. The relevance of this meeting to the DOE derives from the fact that low dose radiation may represent one of t… more

2012 MUTAGENESIS GORDON RESEARCH CONFERENCE, AUGUST 19-23, 2012

Description: The delicate balance among cellular pathways that control mutagenic changes in DNA will be the focus of the 2012 Mutagenesis Gordon Research Conference. Mutagenesis is essential for evolution, while genetic stability maintains cellular functions in all organisms from microbes to metazoans. Different systems handle DNA lesions at various times of the cell cycle and in different places within the nucleus, and inappropriate actions can lead to mutations. While mutation in humans is closely linked … more

Acceptable Knowledge Summary Report for Waste Stream: SR-T001-221F-HET/Drums

Description: Since beginning operations in 1954, the Department of Energy's Savannah River Site FB-Line conducted atomic energy defense activities consistent with the listing in Section 10101(3) of the Nuclear Waste Policy Act of 1982. The facility mission was to process and convert dilute plutonium solution into highly purified weapons grade plutonium metal. As a result of various activities conducted in support of the mission (e.g., operation, maintenance, repair, clean up, and facility modifications), th… more

Accident Management & Risk-Based Compliance With 40 CFR 68 for Chemical Process Facilities

Description: A risk-based logic model is suggested as an appropriate basis for better predicting accident progression and ensuing source terms to the environment from process upset conditions in complex chemical process facilities. Under emergency conditions, decision-makers may use the Accident Progression Event Tree approach to identify the best countermeasure for minimizing deleterious consequences to receptor groups before the atmospheric release has initiated. It is concluded that the chemical process … more

Accurate labeling of the light-actinide O4,5 ionization edges

Description: In this short article the accurate labeling of the O4,5 edges of the light actinides is addressed. The O4 and O5 edges are both contained in what is termed the ''giant resonance'' and the smaller ''pre-peak'' that is observed is a consequence of first-order perturbation by the 5d spin-orbit interaction. Thus, the small prepeak in the actinide 5d {yields} 5f transition should not be labeled the O5 peak, but rather the {Delta}S=1 peak.

Achromat With Linear Space Charge for Bunched Beams

Description: The standard definition for an achromat is a transport line having zero values for the spatial dispersion (R16) and the angular dispersion (RZ6). For a bunched beam with linear space charge this definition of achromaticity does not hold. The linear space charge in the presence of a bend provides coupling between (a) bunch spatial width and bunch length (R1.5) and (b) bunch angular spread and bunch length (R25). Therefore, achromaticity should be redefined as a line having zero values of the spa… more

Action plan for response to excessive temperatures in Hanford site high-heat waste tank 241-C-106

Description: Tank 241-C-106 is a single shell tank at the Hanford Site in south central Washington State, and is the only tank on Hanford`s High-Heat Tank Watch List. This action plan defines possible abnormal conditions (such as ventilation system failure or a leaking tank) that could lead to excessive temperature increases in tank 241-C-106, and documents pre-planned contingency actions would effectively mitigate the consequences of such increased temperatures. Potential structural damage may result from … more

Active Creation of Instrinsically Localized Vibrations in Uranium Using X-Ray and Neutron Scattering

Description: In real materials, nonlinear forces cause the frequencies of vibrating atoms to depend on amplitude. As a consequence, a large-amplitude fluctuation on the scale of the atom spacing can develop a frequency that does not resonate with the normal modes, causing energy to become trapped in an intrinsically localized mode (ILM)--also called 'discrete breather' or 'lattice soliton'. As temperature is increased, entropy is expected to stabilize increased concentrations of these random hotspots. This … more

Advances in laser driven accelerator R&D

Description: Current activities (last few years) at different laboratories, towards the development of a laser wakefield accelerator (LWFA) are reviewed, followed by a more in depth discussion of results obtained at the L'OASIS laboratory of LBNL. Recent results on laser guiding of relativistically intense beams in preformed plasma channels are discussed. The observation of mono-energetic beams in the 100 MeV energy range, produced by a channel guided LWFA at LBNL, is described and compared to results obtai… more

Afghanistan: Current Issues and U.S. Policy

Description: The United States and its allies are helping Afghanistan emerging from more than 22 years of warfare, although substantial risk to Afghan stability remains. Before the U.S. military campaign against the orthodox Islamist Taliban movement began on October 7, 2001, Afghanistan had been mired in conflict since the Soviet invasion of Afghanistan in 1979. The defeat of the Taliban has enabled the United States and its coalition partners to send forces throughout Afghanistan to search for Taliban and… more

Afghanistan: Post-War Governance, Security, and U.S. Policy

Description: Afghanistan's political transition was completed with the convening of a parliament in December 2005, but since then insurgent threats to Afghanistan's government have escalated to the point that some experts are questioning the future of U.S. stabilization efforts. Afghan citizens are enjoying new personal freedoms that were forbidden under the Taliban. Women are participating in economic and political life. U.S. stabilization measures focus on strengthening the central government and its secu… more
