Magnetic field in the SSC arc quad

Description: In part one we report on field calculations along the conductor in the end region of the SSC arc-quad. We have determined that the maximum field in the 2D section is 5.04 tesla located at the pole turn of the inner layer somewhere in the middle of the cable (strand 9)(fields are at 6500 A). At the end'' the maximum field is slightly higher 5.09 tesla located at the overpass (strand 11). The iron contribution was included assuming infinite permeability. In part two we include results of a 3D rep… more

Full scale field test of the in situ air stripping process at the Savannah River integrated demonstration test site

Description: Under sponsorship from the US Department of Energy, technical personnel from the Savannah River Laboratory (SRL) and other DOE laboratories, universities and private industry have completed a full scale demonstration of environmental remediation using horizontal wells. This demonstration was performed as Phase I of an Integrated Demonstration Project designed to evaluate innovative remediation technologies for environmental restoration of sites contaminated with organic contaminants. The demons… more

Calculations of bottom quark production at hadron colliders

Description: This thesis studies Monte Carlo simulations of QCD heavy flavor production processes (p{bar p} {yields} Q({anti Q})X) at hadron colliders. ISAJET bottom quark cross-sections are compared to the O({alpha} {sub s}{sup 3}) perturbative calculation of Nason, Dawson, and Ellis. These Monte Carlo cross-sections are computed from data samples which use different parton distribution functions and physics parameters. Distributions are presented in the heavy quark's transverse momentum and rapidity. Corr… more

Final Report of Investigation of the Acoustic Decay Instability in Laser Plasma Interaction

Description: we have made extensive studies of the Ion Acoustic Decay Instability (IADI) in laser-produced plasmas using the Janus (Phoenix) laser at LLNL. We found that the threshold is quite low and that, in planar plasmas, it can be reduced to homogeneous-plasma, collisional values. These observations are consistent with the plasma-density profiles calculated by hydrodynamic simulations using the LASNEX computer code run with a flux limiter of f = 0.1. We have designed experiments to study the IADI in la… more

Savannah River Site computing architecture

Description: A computing architecture is a framework for making decisions about the implementation of computer technology and the supporting infrastructure. Because of the size, diversity, and amount of resources dedicated to computing at the Savannah River Site (SRS), there must be an overall strategic plan that can be followed by the thousands of site personnel who make decisions daily that directly affect the SRS computing environment and impact the site's production and business systems. This plan must … more

Inverse Cerenkov laser accelerator experiment annual report. 1990 Annual report

Description: During the past year further progress was made on preparations for the Spectra Technology, Inc. (STI) inverse Cerenkov acceleration (ICA) experiment to be performed on the Accelerator Test Facility (ATF) at Brookhaven National Laboratory. Major progress was made in the design and fabrication of the experimental apparatus. This includes the gas cell, where the ICA process occurs, and the optical system that converts the CO{sub 2} laser beam into a radially polarized beam. In terms of progress on… more

Pilot test of a vacuum extraction system for environmental remediation of chlorinated solvents at the Savannah River Site

Description: Vacuum extraction is an environmental restoration technique that is currently being applied to the remediation of soils and shallow segments that are contaminated with volatile constituents. In 1987, a h study was performed to evaluate the performance and potential applicability of this technology at the Savannah River Site (SRS). Vacuum extraction is useful when volatile constituents are present in the vadose zone. The technology has been used to remediate a number of sites across the country,… more

D0 Detector Assemble Hall Platform Oxygen Deficiency Hazard Analysis

Description: Liquid cryogens, released and warming to atmosphere conditions, expand to, on average, seven hundred times their liquid volume, and displace vital atmospheric oxygen. An oxygen deficiency hazard analysis assesses the increased risk to personnel in areas containing cryogenic systems. The D0 detector platform area ODH analysis has been approached four different ways using established methods. In each case, the analysis shows the platform area to be ODH class 0 as equipped (with ventilation fans) … more

Robust incremental condition estimation

Description: This paper presents an improved version of incremental condition estimation, a technique for tracking the extremal singular values of a triangular matrix as it is being constructed one column at a time. We present a new motivation for this estimation technique using orthogonal projections. The paper focuses on an implementation of this estimation scheme in an accurate and consistent fashion. In particular, we address the subtle numerical issues arising in the computation of the eigensystem of a… more

National Emergency Powers

Description: This report the National Emergencies Act (50 U.S.C. 1601-1651) that eliminated or modified some statutory grants of emergency authority, required the President to declare formally the existence of a national emergency and to specify what statutory authority, activated by the declaration, would be used, and provided Congress a means to countermand the President's declaration and the activated authority being sought.

Coal desulfurization in a rotary kiln combustor

Description: Several issues that could have an impact on the capability to burn anthracite culm in a rotary bed boiler were identified; specifically, questions were raised concerning the specifications of the anthracite culm itself and some relating to the equipment. The anthracite culm delivered was wet, (with more than 10 percent moisture), and coarser than feed material for fluidized boilers. It was felt that using finer fuel, ensuring that it is largely dry, would aid the combustion of anthracite culm. … more
