Scattering effects induced by edge density fluctuations on lower hybrid (LH) wave propagation are investigated. The scattering model used here is based on the work of Bonoli and Ott [Phys. Fluids 25 (1982) 361]. It utilizes an electromagnetic wave kinetic equation solved by a Monte Carlo technique. This scattering model has been implemented in GENRAY , a ray tracing code which explicitly simulates wave propagation, as well as collisionless and collisional damping processes, over the entire plasma discharge, including the scrape-off layer (SOL) that extends from the separatrix to the vessel wall. A numerical analysis of the LH wave trajectories and the power deposition profile with and without scattering is presented for Alcator CMod discharges. Comparisons between the measured hard x-ray emission on Alcator C-Mod and simulations of the data obtained from the synthetic diagnostic included in the GENRAY/CQL3D package are shown, with and without the combination of scattering and collisional damping. Implications of these results on LH current drive are discussed.

ITER diagnostic port plugs perform many functionsincluding structural support of diagnostic systems under high electromagnetic loads while allowing for diagnostic access to the plasma. The design of diagnostic equatorial port plugs (EPP) are largely driven by electromagnetic loads and associate responses of EPP structure during plasma disruptions and VDEs. This paper summarizes results of transient electromagnetic analysis using Opera 3d in support of the design activities for ITER diagnostic EPP. A complete distribution of disruption loads on the Diagnostic First Walls (DFWs), Diagnostic Shield Modules (DSMs) and the EPP structure, as well as impact on the system design integration due to electrical contact among various EPP structural components are discussed.

Progress is reported in addressing these questions: Why do hcef mutants have increased CEF1? Is increased CEF1 caused by elevated expression or altered regulation of CEF1 components? Which metabolic pools can be regulators of CEF1? Do metabolites influence CEF1 directly or indirectly? Which CEF1 pathways are activated in high CEF1 mutants? Is PQR a proton pump? Is elevated CEF1 activated by state transitions?

This project focused on advancing radio-frequency (RF) lamination technology closer to commercial implementation, in order to reduce the energy intensity of glass lamination by up to 90%. Lamination comprises a wide range of products including autoglass, architectural safety and innovative design glass, transparent armor (e.g. bullet proof glass), smart glass, mirrors, and encapsulation of photovoltaics. Lamination is also the fastest growing segment of glass manufacturing, with photovoltaics, architectural needs, and an anticipated transition to laminated side windows in vehicles. The state-of-the-art for glass lamination is to use autoclaves, which apply heat and uniform gas pressure to bond the laminates over the course of 1 to 18 hours. Laminates consist of layers of glass or other materials bonded with vinyl or urethane interlayers. In autoclaving, significant heat energy is lost heating the chamber, pressurized air, glass racks, and the glass. In RF lamination, the heat is generated directly in the vinyl interlayer, causing it to heat and melt quickly, in just 1 to 10 minutes, without significantly heating the glass or the equipment. The main purpose of this project was to provide evidence that low energy, rapid RF lamination quality met the same standards as conventionally autoclaved windows. The development of …

This report attempts to summarize the current state of knowledge regarding energy storage technologies for both electric power grid and electric vehicle applications. It is intended to serve as a reference for policymakers interested in understanding the range of technologies and applications associated with energy storage, comparing them, when possible, in a structured way to highlight key characteristics relevant to widespread use. While the emphasis is on technology, this report also addresses the significant policy, market, and other non-technical factors that may impede storage adoption. It considers eight major categories of storage technology: pumped hydro, compressed air, batteries, capacitors, superconducting magnetic energy storage, flywheels, thermal storage, and hydrogen.

Testimony issued by the Government Accountability Office with an abstract that begins "As requested, this statement summarizes our two reports being released today on (1) the status, plans, and risks for JPSS and (2) the status, schedule management process, and risk management process within the GOES-R program. We found that the JPSS cost and GOES-R contractor cost data were sufficiently reliable for our purposes. Further, while we found that the GOES-R schedule and management reserve data were not sufficiently reliable, we reported on the data’s shortcomings in our report."

Equilibrium reconstruction is commonly applied to axisymmetric toroidal devices. Recent advances in computational power and equilibrium codes have allowed for reconstructions of three-dimensional fields in stellarators and heliotrons. We present the first reconstructions of finite beta discharges in the Large Helical Device (LHD). The plasma boundary and magnetic axis are constrained by the pressure profile from Thomson scattering. This results in a calculation of plasma beta without a-priori assumptions of the equipartition of energy between species. Saddle loop arrays place additional constraints on the equilibrium. These reconstruction utilize STELLOPT, which calls VMEC. The VMEC equilibrium code assumes good nested flux surfaces. Reconstructed magnetic fields are fed into the PIES code which relaxes this constraint allowing for the examination of the effect of islands and stochastic regions on the magnetic measurements.

A soft metal with low wear resistance (6000 series aluminum), was used to minimize run time while maximizing wear rate. Two paddle configurations were tested, with the first four paddles after the augers replaced by the wear paddles. The first configuration was all flat paddles, with the first paddle not aligned with the augers and is consistent with present SPF mixer. The second configuration had helical paddles for the first three stages after the augers and a flat paddle at the fourth stage. The first helical paddle was aligned with the auger flight for the second configuration. The all flat paddle configuration wear rate was approximately double the wear rate of the helical paddles for the first two sets of paddles after the augers. For both configurations, there was little or no wear on the third and fourth paddle sets based on mass change, indicating that the fully wetted premix materials are much less abrasive than the un-wetted or partially wetted premix. Additionally, inspection of the wear surface of the paddles at higher magnification showed the flat paddles were worn much more than the helical and is consistent with the wear rates. Aligning the auger discharge flight with the first …

In fiscal year 2012, it was desired to combine a visible spectrometer with a streak camera to form a diagnostic system for recording time-resolved spectra generated in light gas gun experiments. Acquiring a new spectrometer was an option, but it was possible to borrow an existing unit for a period of months, which would be sufficient to evaluate both “off-line” and in-gas gun shots. If it proved adequate for this application, it could be duplicated (with possible modifications); if not, such testing would help determine needed specifications for another model. This report describes the evaluation of the spectrometer (separately and combined with the NSTec LO streak camera) for this purpose. Spectral and temporal resolutions were of primary interest. The first was measured with a monochromatic laser input. The second was ascertained by the combination of the spectrometer’s spatial resolution in the time-dispersive direction and the streak camera’s intrinsic temporal resolution. System responsivity was also important, and this was investigated by measuring the response of the spectrometer/camera system to black body input—the gas gun experiments are expected to be similar to a 3000K black body—as well as measuring the throughput of the spectrometer separately over a range of visible light provided …

This report outlines many of the budgetary procedures that are performed by the President, the Office of Management and Budget (OMB), and agencies. This report provides an overview of the development, submission, and justification of the President’s budget proposal. This report also describes how the President, OMB, and agencies execute the federal budget following the enactment of appropriations and other budgetary legislation by Congress.

The Magnetic Reconnection Experiment (MRX)[1] has been utilized to assess the effectiveness of minimum variance analysis on the magnetic field (MVAB) and boundary-crossing time analysis (BCTA). The neutral sheet is swept, or jogged, in a controlled manner with respect to the stationary probes by pulsed internal coil currents. Magnetic field data from measurement points resembling data from multi-spacecraft flying though a reconnecting current sheet is used to check both techniques to deduce a proper normal vector. We examine discharges with the two-dimensional (2-D) X-line structure as well as cases in which a flux rope forms within the layer. All discharges are in a two-fluid regime in which electrons are magnetized but not ions. Boundary-crossing time analysis with four sample measurement points forming a tetrahedron generates a reasonable unit normal vector and relative velocity along the normal vector for all of the tested cases. On the other hand, MVAB sometimes fails to predict a proper normal direction. This is because the X-line magnetic geometry is fundamentally 2-D or 3-D. However, the direction along the reconnecting field determined by MVAB does not deviate much from the real magnetic geometry documented by 2-D magnetic probe arrays and one additional probe at a different …

A letter report issued by the Government Accountability Office with an abstract that begins "Agencies use a risk-based approach, including workload and threat assessment data, to allocate resources, but most do not fully track those used for export control enforcement activities. As their missions are broader than export controls, agencies can use staff resources for other activities based on need, making tracking resources used solely for export control enforcement difficult. Only Commerce’s Office of Export Enforcement allocates its resources exclusively to export control enforcement as that is its primary mission. Other agencies, such as State and the Treasury, have relatively few export control enforcement staff to track. While several agencies acknowledge the need to better track export enforcement resources and have taken steps to do so, they do not know the full extent of their use of these resources and do not use this information in resource allocation decisions. In some cities, agencies are informally leveraging export enforcement resources through voluntarily created local task forces that bring together enforcement resources to work collectively on export control cases."

Maximizing the utility of upcoming photometric cluster surveys requires a thorough understanding of the richness-mass relation of galaxy clusters. We use Monte Carlo simulations to study the impact of various sources of observational scatter on this relation. Cluster ellipticity, photometric errors, photometric redshift errors, and cluster-to-cluster variations in the properties of red-sequence galaxies contribute negligible noise. Miscentering, however, can be important, and likely contributes to the scatter in the richness - mass relation of galaxy maxBCG clusters at the low mass end, where centering is more difficult. We also investigate the impact of projection effects under several empirically motivated assumptions about cluster environments. Using SDSS data and the maxBCG cluster catalog, we demonstrate that variations in cluster environments can rarely ({approx} 1%-5% of the time) result in significant richness boosts. Due to the steepness of the mass/richness function, the corresponding fraction of optically selected clusters that suffer from these projection effects is {approx} 5%-15%. We expect these numbers to be generic in magnitude, but a precise determination requires detailed, survey-specific modeling.

The federal budget is central to Congress's ability to exercise its "power of the purse." Over the last several fiscal years the imbalance between spending and revenues has grown as a result of the economic downturn and policies enacted in response to financial turmoil. This report discusses how a growing budget deficit will affect the FY2013 budget and government spending.

Correspondence issued by the Government Accountability Office with an abstract that begins "In summary, BOP uses different factors in estimating the daily costs of its facilities and community corrections and incorporating certain additional factors would increase the daily cost per inmate for its facilities. Specifically, BOP estimates daily costs per inmate for its prison facilities using operational costs such as staff salaries and training, inmate food, and medical supplies, among other things, but does not include factors such as construction of new prisons, certain modernization and repair (M&R) projects, or depreciation of its existing facilities. According to BOP, these M&R projects and depreciation are incorporated into budget requests, financial statements, and a user fee BOP computes to bill states for the full costs of housing state prisoners. Adding these costs into BOP’s estimates would raise the costs from between $4.39 and $4.82 per day per inmate for the last 3 fiscal years. For community corrections, BOP estimates daily costs using the contract per diem rates paid to the private companies that operate RRCs and monitor inmates on home detention and the costs of management and oversight by BOP Community Corrections officials and subtracts out subsistence fees paid by inmates in …

Retirement annuities for civilian federal employees are provided mainly through two programs: the Civil Service Retirement System (CSRS) and the Federal Employees Retirement System (FERS). These annuities are financed through a combination of employee contributions and payments made by the federal government to the civil service retirement trust fund. This report discusses the two programs, how they work, and how they are financed.

In the early 1990s, Congress recognized that several federal agencies had ongoing high performance computing programs, but no central coordinating body existed to ensure long-term coordination and planning. To provide such a framework, Congress passed the High-Performance Computing and Communications Program Act of 1991 to enhance the effectiveness of the various programs. In conjunction with the passage of the act, the White House Office of Science and Technology Policy released Grand Challenges: High-Performance Computing and Communications. Current concerns are the role of the federal government in supporting IT R&D and the level of funding to allot to it. This report also looks at federal budgets for the Networking and Information Technology Research and Development Program.

A letter report issued by the Government Accountability Office with an abstract that begins "To collaborate with state and local law enforcement, the Federal Protective Service (FPS) uses memorandums of understanding (MOU), long-standing working relationships, written guidance to FPS staff, joint operations, and other initiatives. For example, FPS has MOUs ranging from sharing radio frequency usage in Alabama, to a mutual aid agreement with the Metropolitan Atlanta Rapid Transit Authority in Georgia. In some jurisdictions, such as the suburbs of the District of Columbia, FPS has no MOUs but has regular contact and long-standing mutual aid relationships with state and local law enforcement. To collaborate with state and local law enforcement, FPS has guidance that addresses issues such as the scope of law enforcement authorities on federal property and information sharing among jurisdictions. FPS established regional staff positions intended to improve collaboration with other organizations and has engaged in joint operations with state and local law enforcement. By comparison, other federal organizations with law enforcement responsibilities similar to FPS also use a variety of methods, ranging from the Department of Veterans Affairs’ policy to seek MOUs with state and local law enforcement to the Smithsonian Institution’s established relationships with the …
