On the massless gap'' adjustment of detected energy for passive material in front of a calorimeter

Description: I have designed a correction scheme for energy losses in passive material in front of a calorimeter based on the massless gap'' idea. I use a flexible geometry model of a calorimeter design for SDC outside of a solenoidal coil made of aluminium cylinders of adjustable thickness. The signal from the first radiation length of active calorimetry is scaled dependent on the incoming and observed energies of the shower. A reasonable recovery of the resolution of an unobstructed calorimeter is achieve… more

The single electron chemistry of coals

Description: Depolymerization of coals at low temperatures may offer advantages over thermal bond cleavage. Because bond cleavage energies of radical cations are lower than the corresponding homolytic bond cleavage energies of the same bond, generation of radical cations in coal may make possible depolymerization at lower temperatures. We seek to investigate the above possibility using single molecules containing functional groups common in coals. Since the generation of a radical cation requires the remova… more

LAPACK users' guide: Release 1. 0

Description: LAPACK is a transportable library of Fortran 77 subroutines for solving the most common problems in numerical linear algebra: systems of linear equations, linear least squares problems, eigenvalue problems and singular value problems. LAPACK is designed to supersede LINPACK and EISPACK, principally by restructuring the software to achieve much greater efficiency on vector processors, high-performance superscalar'' workstations, and shared-memory multi-processors. LAPACK also adds extra function… more

Advanced soluble hydroliquefaction and hydrotreating catalysts

Description: The purpose of the present program is to develop soluble analogs of surface confined catalysts that can be impregnated directly into the coal structure at low temperatures. This approach should avoid problems related to surface area dependence, a two phase (surface- liquid) reaction system and, mass transport limitations.

Rapid pressure swing absorption cleanup of post-shift reactor synthesis gas

Description: In order to increase the production rate of purified gas stream, a new hollow fiber module has been fabricated with more number of hollow fibers. A few experiments have also been carried out using a CO{sub 2}-N{sub 2} feed gas mixture and water as an absorbent in the new module. With the new module, it was possible to increase the production rate of purified gas by a significant amount while the cycle time for vacuum desorption was considerably reduced. Preparations are now being made to study … more

A comparison of ROChem reverse osmosis and spiral wound reverse osmosis membrane modules

Description: Testing of the ROChem Disc Tube[reg sign] reverse osmosis (RO) module's performance on biologically active feed waters has been completed. Both the ROChem module (using Filmtec standard-rejection seawater membranes) and the Filmtec spiral-wound membrane module (using Filmtec high-rejection seawater membranes) were tested with stimulant solutions containing typical bacteria and metal hydroxide levels found in the F/H Effluent Treatment Facility (ETF) influent. Results indicate that the ROChem mo… more

Simulant composition for the Mixed Waste Management Facility (MWMF) groundwater remediation project

Description: A project has been initiated at the request of ER to study and remediate the groundwater contamination at the Mixed Waste Management Facility (MWMF). This water contains a wide variety of both inorganics (e.g., sodium) and organics (e.g., benzene, trichloroethylene). Most compounds are present in the ppB range, and certain components (e.g., trichloroethylene, silver) are present at concentrations that exceed the primary drinking water standards (PDWS). These compounds must be reduced to accepta… more

Measurement of Ripple in the Accumulator Bend Bus Supply

Description: E760 uses the longitudinal Schottky spectrum of the circulating beam in the Accumulator to measure the momentum spectrum of the beam with the assumption that {Delta}p/p = 1/{eta} * {Delta} f/f. However, the presence of low frequency ripple in the bus current could modulate this spectrum so that the above relation is not true. Therefore an attempt was made to measure this ripple to see if it had a significant affect on the frequency spectrum.

Recent characterization activities of Midway Valley as a potential repository surface facility site

Description: Midway Valley, located at the eastern base of Yucca Mountain, Nye County, Nevada, has been identified as a possible location for the surface facilities of a potential high-level nuclear-waste repository. This structural and topographic valley is bounded by two north- trending, down-to-the-west normal faults: the Paintbrush Canyon fault on the east and the Bow Ridge fault on the west. Surface and near-surface geological data have been acquired from Midway Valley during the past three years with … more
