3-D surface profile measurements of large x-ray synchrotron radiation mirrors using stitching interferometry.
Stitching interferometry, using small-aperture, high-resolution, phase-measuring interferometry, has been proposed for quite some time now as a metrology technique to obtain 3-dimensional profiles of surfaces of oversized optical components and substrates. The aim of this work is to apply this method to the specific case of long grazing-incidence x-ray mirrors, such as those used in beamlines at synchrotron radiation facilities around the world. Both fabrication and characterization of these mirrors would greatly benefit from this technique because it offers the potential for providing measurements with accuracy and resolution better than those obtained using existing noncontact laser profilers, such as the long trace profiler (LTP). Measurement data can be used as feedback for computer-controlled fabrication processes to correct for possible topography errors. The data can also be used for simulating and predicting mirror performance under realistic conditions. A semiautomated stitching system was built and tested at the X-ray Optics Metrology Laboratory of the Advanced Photon Source at Argonne National Laboratory. The initial objective was to achieve a measurement sensitivity on the order of 1 {micro}rad rms. Preliminary tests on a 1 m-long x-ray mirror showed system repeatability of less than 0.6 {micro}rad rms. This value is comparable to that of a …

The 2002 Farm Bill: Overview and Status
This report discusses the provisions of the 1996 farm bill, which was due to expire in 2002 but was extended for an additional 6 years on May 13, 2002 by President Bush (P.L. 107-171). The new law is called the "Farm Security and Rural Investment Act (FSRIA) of 2002. The new law generally supersedes the previous omnibus farm bill, the Federal Agriculture Improvement and Reform (FAIR) Act of 1996 (P.L. 104-127). The new farm law has attracted widespread criticism both in the U.S. and abroad. This report discusses these criticisms as well as the defenses of the law's proponents.

2D/3D quench simulation using ANSYS for epoxy impregnated Nb3Sn high field magnets
A quench program using ANSYS is developed for the high field collider magnet for three-dimensional analysis. Its computational procedure is explained. The quench program is applied to a one meter Nb{sub 3}Sn high field model magnet, which is epoxy impregnated. The quench simulation program is used to estimate the temperature and mechanical stress inside the coil as well as over the whole magnet. It is concluded that for the one meter magnet with the presented cross section and configuration, the thermal effects due to the quench is tolerable. But we need much more quench study and improvements in the design for longer magnets.

An Ab Initio Approach Towards Engineering Fischer-Tropsch Surface Chemistry
As the US seeks to develop an energy strategy that reduces the reliance on foreign oil, there is a renewed interest in research and development of the Fischer Tropsch synthesis of converting syngas into long chain hydrocarbon products. This report investigates some of the basic elementary steps for Fischer-Tropsch synthesis over ideal Co and Ru metal surfaces by using ab initio density functional theoretical calculations. This includes activation of CO of CO, the hydrogenation of CH{sub x} intermediates, and the adsorption and dissociation of water. The activation of CO is studied in detail showing a strong dependence on the surface coverage, defect sites and Co-Ru alloy formation. The barriers for CO activation over the ideal (0001) surfaces are quite high making CO activation at the terrace sites unlikely under operating conditions. The calculations for the overall reaction energies at the step edges indicate that these sites are much more reactive. The hydrogenation of the CHx intermediates occurs in a sequential fashion. CH1 was found to be the most stable intermediate over various surfaces. The barriers to form both CH* as well as CH{sub 4} are both found to be highly activated and potentially difficult steps. Water which is a reaction …

Absorption Spectra of Broadened Sodium Resonance Lines in Presence of Rare Gases
The pressure broadening of alkali-metal lines is a fundamental problem with numerous applications. For example, the sodium resonance lines broadened by xenon are important in the production of broad spectra emitted in the HPS (High-Pressure Sodium) lamp and they potentially can be used for gas condition diagnostics. Broadened absorption lines of alkali-metal atoms are prominent in the optical spectra of brown dwarfs and understanding the broadening mechanism will help elucidate the chemical composition and atmospheric properties of those stars. The far-line wing spectra of sodium resonance lines broadened by rare gases are found to exhibit molecular characteristics such as satellites and hence the total absorption coefficients for vapors of Na atoms and perturbing rare gas atoms can be modeled as Na-RG (rare gas) molecular absorption spectra. In this work, using carefully chosen interatomic potentials for Na-RG molecules we carry out quantum-mechanical calculations for reduced absorption coefficients for vapors composed of Na-He, Na-Ar, and Na-Xe. Calculated spectra are compared to available experimental results and the agreement is good in the measured satellite positions and shapes.

Acceleration of Polarized Protons at Rhic.
Relativistic Heavy Ion Collider (RHIC) ended its second year of operation in January 2002 with five weeks of polarized proton collisions. Polarized protons were successfully injected in both RHIC rings and maintained polarization during acceleration up to 100 GeV per ring using two Siberian snakes in each ring. This is the first time that polarized protons have been accelerated to 100 GeV. The machine performance and accomplishments during the polarized proton run will be reviewed. The plans for the next polarized proton run will be outlined.

ACCURATE QUANTIFICATION OF RADIOACTIVE MATERIALS BY X-RAY FLUORESCENCE: GALLIUM IN PLUTONIUM METAL.
Determining the concentration of gallium in plutonium metal is imperative in manufacturing nuclear weapons. X-ray fluorescence (XRF) is an effective method used to quantify the gallium content in plutonium; however, the sample and specimen preparation methods currently employed could be improved from a time and safety standpoint. Recently, a dried residue specimen preparation method was developed as an alternative to the established aqueous approach. The method currently certified to prepare plutonium for gallium analysis by XRF involves dissolving the sample and removing the plutonium with ion exchange chromatography. The gallium remaining in solution is then analyzed. This method has been thoroughly developed, and relative accuracy and precision values less than 1% can be achieved. However, this process is time consuming, and the specimen solution is radioactive due to the presence of residual plutonium and trace americium. Thus, an alternate process was developed to avoid these issues in which the plutonium solution is cast in {mu}L spots on Mylar XRF film, dried, and sealed inside a sample cell for analysis. This specimen preparation method is considerably faster and also safer than the solution process. Previous studies have demonstrated that a very linear calibration can be obtained from dried residue standards. In …

Acid Gas Removal by Customized Sorbents for Integrated Gasification Fuel Cell Systems
In order to reduce exergy losses, gas cleaning at high temperatures is favored in IGFC systems. As shown by thermodynamic data, separation efficiencies of common sorbents decrease with increasing temperature. Therefore, acid gas removal systems have to be developed for IGFC applications considering sorbent capacity, operation temperature, gasification feedstock composition and fuel cell threshold values.
