GEM Technical Design Report

Description: The GEM collaboration was formed in June 1991 to develop a major detector for the SSC. The primary physics objectives of GEM are those central to the motivation for the SSC, to study high p{sub T} physics - exemplified by the search for Higgs bosons - and to search for new physics beyond the standard model. The authors present in this Technical Design Report (TDR) a detector with broad capabilities for the discovery and subsequent study of electroweak symmetry breaking, the origin of mass and f… more

Instrumentation of Dynamic Gas Pulse Loading system. Final technical report

Description: The Dynamic Gas Pulse Loading (DGPL) process is an hydraulic fracturing method which uses CO{sub 2} and CO gas as a working fluid instead of a liquid. The DGPL system can be used to generate fractures for horizontal and vertical oil and gas well completions in both open hole and perforated casing. The DGPL system provides a cost effective tool for repairing near well bore permeability damage caused by inappropriate chemical treatment, migrating fines and paraffins, or slotted liners blocked by … more

Applications and source development for high-repetition rate x-ray lasers

Description: Many applications in material science, chemistry, and atomic physics require an x-ray source that has a repetition rate of 1 Hz to a few kHz. In these fields, a very wide range of photon energies is of interest. One application is time-resolved surface photoelectron spectroscopy and microscopy where low energy (< 1{mu}J) pulses are required to avoid space charge effects but high-repetition rates ({approx} kHz) provide the high average power which is needed to obtain the desired resolution. In p… more

Assist in the Recovery of Bypassed Oil From Reservoirs in the Gulf of Mexico. Quarterly Status Report, April 1, 1993--June 30, 1993

Description: Much of the remaining oil offshore is trapped in formations that are extremely complex due to intrusions of salt domes. Conventional seismic processing techniques cannot clearly image either these traps or the full extent of oil-bearing segments near the salt domes; therefore, substantial volumes of oil may have remained uncontacted by previous drilling. Recently, however, significant innovations have been made in seismic processing and mathematical migration of seismic signal. In addition, sig… more

Bench-scale testing of the Multi-Gravity separator in combination with Microcel. Third quarterly report, April 1, 1993--June 30, 1993

Description: The primary objective of the proposed work is to design, install, and operate an advanced fine coal processing circuit combining the Microcel and Multi-Gravity-Separator (MGS) technologies. Both of these processes have specific advantages as stand-alone units. For example, the Microcel column effectively removes ash-bearing mineral matter, while the MGS efficiently removes coal-pyrite composites. By combining both unit operations into a single processing circuit, synergistic advantages can be g… more

Design and early results of the sodium-layer laser guide star adaptive optics experiment at the Lawrence Livermore National Laboratory

Description: Adaptive optic systems promise to give diffraction limited performance to ground based telescopes operating at visible and near infrared wavelengths. However, because of the short spatial scale of atmospheric turbulence, the corrected field of view is limited to only a few arc seconds in the visible, to perhaps 10 arc seconds at L band (3.5 {mu}). A bright point source must be in this field of view as a wavefront reference, but the number density of natural stars is too small for full sky cover… more

Feasibility of the Shallow High Resolution Seismic Reflection Technique for Use at the Hanford Site

Description: Data obtained during site characterization should be useful to assess the need for remediation, to evaluate and design effective remedial plans, and to allow long-term monitoring to discern remediation effectiveness. A valuable environmental tool that incorporates this data is a model that describes groundwater and vadose zone flow and transport characteristics. Data on geology and hydrology combined with information on contaminant sources are incorporated into these conceptual models that deli… more

Potential for radiation damage to carbon steel storage tanks for high level radioactive waste

Description: A low intensity radiation field is generated by the high level waste that is stored within carbon steel lined tanks at the Savannah River Site (SRS). The highest level of radiation damage to the tank walls from gamma and spontaneous neutron emissions is estimated to be less than 1.0E-6 displacements per atom (DPA) for a 100 year exposure to fresh, ``high heat`` SRS waste assuming continuous replenishment of the radionuclides. This damage level is below the limit for measurable radiation damage … more

Pulsed atmospheric fluidized bed combustion. Quarterly technical progress report, April--June 1993

Description: In this quarter the design of the plant structures was completed 70%. The design philosophy of the structure economizes on the use of steel by providing supports for the hot cyclone and hot gas duct connecting the cyclone to the boiler while fulfilling the needs for platforms and walkways at the various levels necessary for operational access. Figures 1 through 6 indicate the layout of the plant structure. At the same time the structure for the Coarse Coal Silo V-2 and Limestone Silo V-4 were i… more

Radiogenic neoplasia in thyroid and mammary clonogens. Progress report, January 1, 1993--December 31, 1993

Description: The induction of cancer by ionizing radiation is a matter of great practical importance to the nuclear industry, to national defense, to radiological medicine and to the general public. It is increasingly apparent that carcinogenesis is one of the leading dose-limiting effects of radiation exposure (Co90). Quantitative information at the cellular level is essential to an understanding of the mechanisms of radiogenic neoplastic initiation and the stages of promotion and progression to overt neop… more

Sound velocity estimation: A system theoretic approach

Description: A system-theoretic approach is proposed to investigate the feasibility of reconstructing a sound velocity profile (SVP) from acoustical hydrophone measurements. This problem is based on a state-space representation of the normal-mode propagation model. It is shown that this representation can be utilized to investigate the so-called observability of the SVP from noisy measurement data. A model-based processor is developed to extract this information and it is shown that even in cases where limi… more

Development of biological coal gasification (MicGas process): 12th Quarterly report

Description: Several experiments were conducted to study the efficiency of granulated sludge consortium (GSC) on the biomethanation of Texas lignite (TxL). With an aim of obtaining a better culture than Mic-1, GSC was used as inoculum at different concentrations. The first experiment was conducted under anaerobic conditions in 60-mL vials containing 40 mL 0.01% SNTM + 1% TxL + 10% GSC. Methane production was measured periodically in the vial headspace and after 20 days of incubation, methane was found to be… more

Fischer-tropsch synthesis in supercritical fluids. Quarterly technical progress report, April 1, 1993--June 30, 1993

Description: We have completed modifications of the Taylor Dispersion Apparatus so that propane can be used as a solvent. Problems were encountered initially compressing propane to the necessary pressures because of cavitation in the liquid pump. This problem was overcome by placing a check valve in the line after the pump and pressures of 2500 psi have been achieved. The system has been pressure tested by using a soap solution on exposed joints and performing a mass balance (leak test). The mass balance wa… more

Modeling the connection between development and evolution: Preliminary report

Description: In this paper we outline a model which incorporates development processes into an evolutionary frame work. The model consists of three sectors describing development, genetics, and the selective environment. The formulation of models governing each sector uses dynamical grammars to describe processes in which state variables evolve in a quantitative fashion, and the number and type of participating biological entities can change. This program has previously been elaborated for development. Its … more
