Betatron motion with coupling of horizontal and vertical degrees of freedom (open access)

Betatron motion with coupling of horizontal and vertical degrees of freedom

The Courant-Snyder parameterization of one-dimensional linear betatron motion is generalized to two-dimensional coupled linear motion. To represent the 4 x 4 symplectic transfer matrix the following ten parameters were chosen: four beta-functions, four alpha-functions and two betatron phase advances which have a meaning similar to the Courant-Snyder parameterization. Such a parameterization works equally well for weak and strong coupling and can be useful for analysis of coupled betatron motion in circular accelerators as well as in transfer lines. Similarly, the transfer matrix, the bilinear form describing the phase space ellipsoid and the second order moments are related to the eigen-vectors. Corresponding equations can be useful in interpreting tracking results and experimental data.

Campaign Financing (open access)

Campaign Financing

This is one report in the series of reports that discuss the campaign finance practices and related issues. Concerns over financing federal elections have become a seemingly perennial aspect of our political system, centered on the enduring issues of high campaign costs and reliance on interest groups for needed campaign funds. The report talks about the today’s paramount issues such as perceived loopholes in current law and the longstanding issues: overall costs, funding sources, and competition.

Ceramic waste form production and development at ANL-West. (open access)

Ceramic waste form production and development at ANL-West.

Argonne National Laboratory has developed a method to stabilize spent electrolyte salt discarded from electrorefiners (ER) used to treat spent nuclear fuel. The salt is stabilized in a ceramic using a pressureless consolidation technique. The starting material is zeolite 4A which is used as the host for the fission product and actinide rich salt. Glass frit is added to the salt loaded zeolite before processing to act as a binder. The zeolite 4A is converted to sodalite during processing via pressureless consolidation. This process differs from one used in the past that employed a hot isostatic press. Ceramic is created at 925 C and atmospheric pressure instead of the high pressures used in hot isostatic pressing. Process flow sheets, off-gas test results, processing equipment, and leech test results are presented.

Characterization of Spatial Variability of Hydrogeologic Properties for Unsaturated Flow in the Fractured Rocks at Yucca Mountain, Nevada (open access)

Characterization of Spatial Variability of Hydrogeologic Properties for Unsaturated Flow in the Fractured Rocks at Yucca Mountain, Nevada

The spatial variability of layer-scale hydrogeologic properties of the unsaturated zone (UZ) at Yucca Mountain, Nevada, is investigated using inverse modeling. The thick UZ is grouped into five hydrostratigraphic units and further into 35 hydrogeologic layers. For each layer, lateral variability is represented by the variations in calibrated values of layer-scale properties at different individual deep boreholes. In the calibration model, matrix and fracture properties are calibrated for the one-dimensional vertical column at each individual borehole using the ITOUGH2 code. The objective function is the summation of the weighted misfits between the ambient unsaturated flow (represented by measured state variables: water saturation, water potential, and pneumatic pressure) and the simulated one in the one-dimensional flow system. The objective function also includes the weighted misfits between the calibrated properties and their prior information. Layer-scale state variables and prior rock properties are obtained from their core-scale measurements. Because of limited data, the lateral variability of three most sensitive properties (matrix permeability, matrix of the van Genuchten characterization, and fracture permeability) is calibrated, while all other properties are fixed at their calibrated layer-averaged values. Considerable lateral variability of hydrogeologic properties is obtained. For example, the lateral variability of is two to three orders …

Charge transport in hybrid nanorod-polymer composite photovoltaiccells (open access)

Charge transport in hybrid nanorod-polymer composite photovoltaiccells

Charge transport in composites of inorganic nanorods and aconjugated polymer is investigated using a photovoltaic device structure.We show that the current-voltage (I-V) curves in the dark can be modelledusing the Shockley equation modified to include series and shuntresistance at low current levels, and using an improved model thatincorporates both the Shockley equation and the presence of a spacecharge limited region at high currents. Under illumination, theefficiency of photocurrent generation is found to be dependent on appliedbias. Furthermore, the photocurrent-light intensity dependence was foundto be sublinear. An analysis of the shunt resistance as a function oflight intensity suggests that the photocurrent as well as the fill factoris diminished as a result of increased photoconductivity of the activelayer at high light intensity. By studying the intensity dependence ofthe open circuit voltage for nanocrystals with different diameters andthus ! band gaps, it was inferred that Fermi-level pinning occurs at theinterface between the aluminum electrode and the nanocrystal.

Charitable Choice, Faith-Based Initiatives, and TANF

The Senate Finance Committee version of H.R. 7, approved on July 16, 2002, does not contain the “charitable choice” title of the House-passed H.R. 7; nor does it include a compromise “faith-based” provision (from S. 1924 as introduced) that sought to assure equal treatment for nongovernmental providers of almost all federally-funded social services. Remaining in the Senate Finance bill are tax incentives to promote private giving. The Charitable Choice Act of 2001 (Title II of the House bill) would apply its rules, which are significantly different from those in four existing charitable choice laws, to nine new program areas.

Chemical Speciation of Inorganic Compounds under Hydrothermal Conditions (open access)

Chemical Speciation of Inorganic Compounds under Hydrothermal Conditions

Measurements of oxidation. These spectra are to the best of our knowledge the first reported in situ spectroscopic observation of homogeneous aqueous redox chemistry at temperatures beyond the critical temperature of waste. We also observed a time-dependence for the growth of the Cr(VI) XANES peak and have therefore obtained both kinetic information as well as structural information on the reactants and products at the reaction temperature. We feel that these new techniques, when employed on actual waste components will elucidate the underlying chemistry.

China-U.S. Relations

This report discusses the background information and most recent development in U.S.-China relations since mid-1996. Since the early 1990s, U.S.-China relations have followed an uneven course, with modest improvements overshadowed by various recurring difficulties and setbacks. Longstanding bilateral difficulties have included U.S. problems with the PRC’s worsening human rights record, growing tensions over the PRC’s southern military build-up opposite Taiwan and Taiwan’s political status, and continued controversy over allegations of Chinese proliferation of weapons to unstable regimes.

Clean Water Act Issues in the 107th Congress (open access)

Clean Water Act Issues in the 107th Congress

Key water quality issues that may face the 107th Congress include: actions to implement existing provisions of the Clean Water Act (CWA), whether additional steps are necessary to achieve overall goals of the Act, and the appropriate federal role in guiding and paying for clean water activities. Legislative prospects for comprehensively amending the Act have for some time stalled over whether and exactly how to change the law. If clean water issues receive attention in the 107th Congress, consideration of specific issues will depend in part on the CWA policy agenda of the new Bush Administration and on priorities of the key committees that have major jurisdiction over the Act.
