Airport and Airway Trust Fund: Factors Affecting Revenue Forecast Accuracy and Realizing Future FAA Expenditures (open access)

Airport and Airway Trust Fund: Factors Affecting Revenue Forecast Accuracy and Realizing Future FAA Expenditures

A letter report issued by the Government Accountability Office with an abstract that begins "Actual trust-fund revenues fell short of FAA’s revenue forecasts for 9 of the past 11 years, contributing to a decline in the trust fund’s uncommitted balance from over $7 billion in fiscal year 2000 to $770 million in fiscal year 2010. Inaccurate forecasts for the taxes related to domestic passenger tickets, which account for over 70 percent of trust-fund revenues, drove the aggregate overforecast, but inaccurate forecasts for other taxes also had an effect. This inaccuracy is largely attributable to unexpected events affecting aviation, such as the terrorist attacks of September 11, 2001, and the recession in 2009; the budget process requiring the forecasts to be developed over a year in advance of the fiscal year; and lags in recognizing structural changes in the airline industry, such as airlines’ increased reliance on ancillary fees for which excise taxes for the trust fund are not collected. Changes in the methodology for forecasting trust-fund revenues and the assumption of forecasting responsibility by Treasury, begun in fiscal year 2011, may also affect the future accuracy of forecasts, but it is too soon to tell what effect the changes will …

Conformal growth of Mo/Si multilayers on grating substrates using collimated ion beam sputtering (open access)

Conformal growth of Mo/Si multilayers on grating substrates using collimated ion beam sputtering

Deposition of multilayers on saw-tooth substrates is a key step in the fabrication of multilayer blazed gratings (MBG) for extreme ultraviolet and soft x-rays. Growth of the multilayers can be perturbed by shadowing effects caused by the highly corrugated surface of the substrates, which results in distortion of the multilayer stack structure and degradation of performance of MBGs. To minimize the shadowing effects we used an ionbeam sputtering machine with a highly collimated atomic flux to deposit Mo/Si multilayers on saw-tooth substrates. The sputtering conditions were optimized by finding a balance between smoothening and roughening processes in order to minimize degradation of the groove profile in the course of deposition and at the same time to keep the interfaces of a multilayer stack smooth enough for high efficiency. An optimal value of energy of 200 eV for sputtering Kr{sup +} ions was found by deposition of test multilayers on flat substrates at a range of ion energies. Two saw-tooth substrates were deposited at energies of 200 eV and 700 eV for the sputtering ions. It was found that reduction of the ion energy improved the blazing performance of the MBG and resulted in a 40% gain in the diffraction efficiency …

Immigration: Noncitizen Eligibility for Needs-Based Housing Programs (open access)

Immigration: Noncitizen Eligibility for Needs-Based Housing Programs

The issue of noncitizen eligibility for federally funded programs, including needs-based housing programs, is a perennial issue in Congress. Noncitizen eligibility varies among the needs-based housing programs administered by the U.S. Department of Housing and Urban Development (HUD), such as Public Housing, Section 8 vouchers and project-based rental assistance, homeless assistance programs, housing for the elderly (§202) and the disabled (§811), the HOME program, and the Community Development Block Grants (CDBG) program. Two laws govern noncitizen eligibility for housing programs: Title IV of the Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (Welfare Reform) and Section 214 of the Housing and Community Development Act of 1980, as amended. There has been congressional interest regarding the implementation of the eligibility requirements for housing programs. Specifically, questions have been raised as to the documentation requirements placed on both citizens and noncitizens in determining eligibility for housing programs. The documentation requirements are dependent on (1) the housing program, (2) the citizenship status of the applicant, and (3) the age of the applicant.

LLNL-Generated Content for the California Academy of Sciences, Morrison Planetarium Full-Dome Show: Earthquake

The California Academy of Sciences (CAS) Morrison Planetarium is producing a 'full-dome' planetarium show on earthquakes and asked LLNL to produce content for the show. Specifically the show features numerical ground motion simulations of the M 7.9 1906 San Francisco and a possible future M 7.05 Hayward fault scenario earthquake. The show also features concepts of plate tectonics and mantle convection using images from LLNL's G3D global seismic tomography. This document describes the data that was provided to the CAS in support of production of the 'Earthquake' show. The CAS is located in Golden Gate Park, San Francisco and hosts over 1.6 million visitors. The Morrison Planetarium, within the CAS, is the largest all digital planetarium in the world. It features a 75-foot diameter spherical section projection screen tilted at a 30-degree angle. Six projectors cover the entire field of view and give a three-dimensional immersive experience. CAS shows strive to use scientifically accurate digital data in their productions. The show, entitled simply 'Earthquake', will debut on 26 May 2012. They are working on graphics and animations based on the same data sets for display on LLNL powerwalls and flat-screens as well as for public release.

Proposed Keystone XL Pipeline: Legal Issues

This report reviews those legal issues. First, it suggests that legislation related to cross-border facility permitting is unlikely to raise significant constitutional questions, despite the fact that such permits have traditionally been handled by the executive branch alone pursuant to its constitutional "foreign affairs" authority. Next, it observes generally that state oversight of pipeline siting decisions does not appear to violate existing federal law or the Constitution. Finally, the report suggests that State Department's implementation of the existing authority to issue presidential permits appears to allow for judicial review of its National Environmental Policy Act determinations.

Simulations of RF capture with barrier bucket in booster at injection (open access)

Simulations of RF capture with barrier bucket in booster at injection

As part of the effort to increase the number of ions per bunch in RHIC, a new scheme for RF capture of EBIS ions in Booster at injection has been developed. The scheme was proposed by M. Blaskiewicz and J.M. Brennan. It employs a barrier bucket to hold a half turn of beam in place during capture into two adjacent harmonic 4 buckets. After acceleration, this allows for 8 transfers of 2 bunches from Booster into 16 buckets on the AGS injection porch. During the Fall of 2011 the necessary hardware was developed and implemented by the RF and Controls groups. The scheme is presently being commissioned by K.L. Zeno with Au32+ ions from EBIS. In this note we carry out simulations of the RF capture. These are meant to serve as benchmarks for what can be achieved in practice. They also allow for an estimate of the longitudinal emittance of the bunches on the AGS injection porch.

Ultra-high efficiency multilayer blazed gratings through deposition kinetic control (open access)

Ultra-high efficiency multilayer blazed gratings through deposition kinetic control

Diffraction efficiency of multilayer coated blazed gratings (MBG) strongly depends on the perfection of the saw-toothshaped layers in the overall composite structure. Growth of multilayers on saw-tooth substrates should be carefully optimized in order to reduce groove profile distortion and at the same time to avoid significant roughening of multilayer interfaces. In this work we report on a new way to optimize growth of sputter-deposited Mo/Si multilayers on saw-tooth substrates through variation of the sputtering gas pressure. A new record for diffraction efficiency of 44% was achieved for a optimized MBG with groove density of 5250 lines/mm at the wavelength of 13.1 nm.

Uranium Oxide Aerosol Transport in Porous Graphite (open access)

Uranium Oxide Aerosol Transport in Porous Graphite

The objective of this paper is to investigate the transport of uranium oxide particles that may be present in carbon dioxide (CO2) gas coolant, into the graphite blocks of gas-cooled, graphite moderated reactors. The transport of uranium oxide in the coolant system, and subsequent deposition of this material in the graphite, of such reactors is of interest because it has the potential to influence the application of the Graphite Isotope Ratio Method (GIRM). The GIRM is a technology that has been developed to validate the declared operation of graphite moderated reactors. GIRM exploits isotopic ratio changes that occur in the impurity elements present in the graphite to infer cumulative exposure and hence the reactor’s lifetime cumulative plutonium production. Reference Gesh, et. al., for a more complete discussion on the GIRM technology.
