Absolute and Relative Surrogate Measurements of the 236U(n,f) Cross Section as a Probe for Angular Momentum Effects (open access)

Absolute and Relative Surrogate Measurements of the 236U(n,f) Cross Section as a Probe for Angular Momentum Effects

Using both the absolute and relative surrogate techniques, the {sup 236}U(n,f) cross section was deduced over an equivalent neutron energy range of 0 to 20 MeV. A 42 MeV {sup 3}He beam from the 88-Inch Cyclotron at Lawrence Berkeley National Laboratory was used to perform a ({sup 3}He,{alpha}) pickup reaction on targets of {sup 235}U (J{sup {pi}}=7/2{sup -}) and {sup 238}U (J{sup {pi}}=0{sup +}) and the fission decay probabilities were determined. The {sup 235}U({sup 3}He,{alpha}f) and {sup 238}U({sup 3}He,{alpha}f) were surrogates for {sup 233}U(n,f) and {sup 236}U(n,f), respectively. The cross sections extracted using the Surrogate Method were compared to directly measured cross sections. The sensitivity of these cross sections to the J{sup {pi}}-population distributions was explored.

BASELINE MEMBRANE SELECTION AND CHARACTERIZATION FOR AN SDE (open access)

BASELINE MEMBRANE SELECTION AND CHARACTERIZATION FOR AN SDE

Thermochemical processes are being developed to provide global-scale quantities of hydrogen. A variant on sulfur-based thermochemical cycles is the Hybrid Sulfur (HyS) Process which uses a sulfur dioxide depolarized electrolyzer (SDE) to produce the hydrogen. In FY05 and FY06, testing at the Savannah River National Laboratory (SRNL) explored a low temperature fuel cell design concept for the SDE. The advantages of this design concept include high electrochemical efficiency and small footprint that are crucial for successful implementation on a commercial scale. A key component of the SDE is the ion conductive membrane through which protons produced at anode migrate to the cathode and react to produce hydrogen. An ideal membrane for the SDE should have both low ionic resistivity and low sulfur dioxide transport. These features allow the electrolyzer to perform at high currents with low potentials, along with preventing contamination of both the hydrogen output and poisoning of the catalysts involved. Another key component is the electrocatalyst material used for the anode and cathode. Good electrocatalysts should be chemically stable and have a low overpotential for the desired electrochemical reactions. This report summarizes results from activities to evaluate commercial and experimental membranes for the SDE. Several different types of …

Design of the First Ferromagnetic Piezoelectric (FINAL TECHNICAL REPORT)

Abstract During the course of the grant we made the following scientific advances: • We developed a thorough understanding of piezoelectricity in antiferromagnetic wurtzite structure MnO. • We explained the absence of ferromagnetism in high quality samples of transition-metal-doped ZnO, and proposed a scheme for obtaining robust ferromagnetism in ZnO-based systems. • We demonstrated that the MgO-ZnO-CdO system is a promising candidate for the production of polarization field-effect transistors.

Generation of Initial Kinetic Distributions for Simulation of Long-Pulse Charged Particle Beams with High Space-Charge intensity (open access)

Generation of Initial Kinetic Distributions for Simulation of Long-Pulse Charged Particle Beams with High Space-Charge intensity

Self-consistent Vlasov-Poisson simulations of beams with high space-charge intensity often require specification of initial phase-space distributions that reflect properties of a beam that is well adapted to the transport channel--both in terms of low-order rms (envelope) properties as well as the higher-order phase-space structure. Here, we first review broad classes of kinetic distributions commonly in use as initial Vlasov distributions in simulations of unbunched or weakly bunched beams with intense space-charge fields including: the Kapchinskij-Vladimirskij (KV) equilibrium, continuous-focusing equilibria with specific detailed examples, and various non-equilibrium distributions, such as the semi-Gaussian distribution and distributions formed from specified functions of linear-field Courant-Snyder invariants. Important practical details necessary to specify these distributions in terms of usual accelerator inputs are presented in a unified format. Building on this presentation, a new class of approximate initial kinetic distributions are constructed using transformations that preserve linear-focusing single-particle Courant-Snyder invariants to map initial continuous-focusing equilibrium distributions to a form more appropriate for non-continuous focusing channels. Self-consistent particle-in-cell simulations are employed to show that the approximate initial distributions generated in this manner are better adapted to the focusing channels for beams with high space-charge intensity. This improved capability enables simulation applications that more precisely probe intrinsic stability …

Internal Revenue Service: Interim Results of the 2007 Tax Filing Season and the Fiscal Year 2008 Budget Request

A letter report issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service's (IRS) tax filing season performance is a key indicator of how well IRS serves taxpayers. This year's filing season was expected to be risky because of tax system changes, including the telephone excise tax refund (TETR). IRS's fiscal year (FY) 2008 budget request shows its spending proposal for taxpayer service, enforcement, and Business Systems Modernization (BSM). The request includes initiatives to reduce the tax gap, the difference between what taxpayers owe and what they voluntarily pay on time. IRS recently estimated the net tax gap to be $290 billion in 2001. GAO was asked to (1) describe IRS's 2007 filing season performance, (2) determine how IRS's proposed FY 2008 budget compares to prior years', provides information on how proposals may impact the tax gap, justifies new spending, and whether there are opportunities to reduce or reallocate resources, and (3) evaluate the status of IRS's efforts to develop and implement BSM."

Interstate Compacts: An Overview of the Structure and Governance of Environment and Natural Resource Compacts (open access)

Interstate Compacts: An Overview of the Structure and Governance of Environment and Natural Resource Compacts

A letter report issued by the Government Accountability Office with an abstract that begins "Interstate compacts are legal agreements between states that are designed to resolve concerns that transcend state lines, such as allocating interstate waters. While some compacts assign their administration to existing state agencies, compacts requiring greater coordination among states may establish an interstate agency, typically called a commission, to administer their provisions. Congress must give its consent to compacts that affect the balance of power between the states and the federal government. An example of a congressionally approved environment and natural resource compact is the Tahoe Regional Planning Compact, which created the Tahoe Regional Planning Agency (TRPA) to administer its provisions. For such compacts, GAO determined (1) the organizational structures, powers and authorities, and dispute resolution and public accountability mechanisms; (2) the extent to which concerns have been raised about the structure and governance of compacts that have commissions; and (3) how the structure and governance of TRPA compares to those of other similar compact commissions. GAO reviewed 59 congressionally approved compacts and surveyed those 45 that had commissions."

Measurements of the Properties of Highly-charged high-Z ions (open access)

Measurements of the Properties of Highly-charged high-Z ions

We had proposed carrying out a systematic experimental investigation of the atomic physics of highly charged, high-Z ions, produced in the Lawrence Livermore National Laboratory (LLNL) electron beam ion trap (EBIT-I) in its high energy mode, superEBIT. In particular we were going to accurately measure line positions for Δn=0 transitions in few electron high-Z ions; this was meant to enable us to investigate relativistic and quantum electrodynamics QED contributions to the energy levels as well as the nuclear properties of heavy ions. We were also going to measure cross sections for various electron-ion interactions, the degree of polarization of emitted x-rays, and radiation cooling rates of various ionization stages of highly charged, high-Z ions. This would enable us to study fundamental atomic physics of high-Z ions at relativistic electron impact energies and in the intense nuclear fields of highly ionized, high-Z ions. This would extend previous measurements we have carried out to a regime where there is a paucity of good data. These measurements were expected to generate increased theoretical interest and activity in this area. The project will extend a very successful collaboration between Morehouse College (MC) and a national laboratory LLNL, Minority student training and development are major …
