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

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

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 achieved using correction factors that depend only upon the total thickness of passive material. Thus a useful correction may be built into the hardware by increasing the amount of scintillator in the first radiation length of the active calorimeter. The distribution of correction factors determined event-by-event indicate that an additional dependence on the observed signal in the massless gap and total incident energy is clearly present.

The single electron chemistry of coals (open access)

The single electron chemistry of coals

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 removal of an electron from a neutral molecule, a primary focus of the study will be finding oxidants that will remove an electron from compounds with structural similarity to those typically found in coals. The study must also be concerned with the decomposition of radical cations and the products formed as a result of the decomposition.

LAPACK users' guide: Release 1. 0 (open access)

LAPACK users' guide: Release 1. 0

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 functionality, uses some new or improved algorithms, and integrates the two sets of algorithms into a unified package. The LAPACK Users' Guide gives an informal introduction to the design of the algorithms and software, summarizes the contents of the package, describes conventions used in the software and documentation, and includes complete specifications for calling the routines. This edition of the Users' guide describes Release 1.0 of LAPACK.

Advanced soluble hydroliquefaction and hydrotreating catalysts (open access)

Advanced soluble hydroliquefaction and hydrotreating catalysts

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 (open access)

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

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 the absorption behavior of CO{sub 2}-N{sub 2} gas mixture with a reactive absorbent liquid such as aqueous diethanolamine solution.

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

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 module gave superior performance over the spiral-wound module. Water flux losses were reduced by over 30% for water recoveries above 40%.

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

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 acceptable levels as per RCRA and CERCLA orders. This report gives a listing of the important constituents which are to be included in a simulant to model the MWMF aquifer. This simulant will be used to evaluate the feasibility of various state of the art separation/destruction processes for remediating the aquifer.

Measurement of Ripple in the Accumulator Bend Bus Supply (open access)

Measurement of Ripple in the Accumulator Bend Bus Supply

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.
