Sources of hot electrons in laser-plasma interaction with emphasis on Raman and turbulence absorption

Description: Heating targets with high power lasers results in a sizable fraction of the absorbed energy going into electrons of temperature much greater than thermal which can pre-heat the pellet core and accelerate fast ion blowoff which results in poor momentum transfer and hence poor compression efficiency. The present emphasis is to build lasers of higher frequency, ..omega../sub 0/, which at the same W/cm/sup 2/ results in more absorption into cooler electrons. Two physical reasons are that the laser … more

Workshop on core and sample curation for the National Continental Scientific Drilling Program

Description: The Workshop on Core and Sample Curation was held to discuss the best means of handling, distributing, and advertising samples and data collected during a Continental Scientific Drilling Program (CSDP) and to establish better communication between sample curators regarding common problems. It was geneerally agreed that CSDP samples should be handled, on a regional basis, by existing data systems and sample repositories judged to have adequate staff and support. Repository design, sample handlin… more

Nuclear reaction uncertainties in standard and non-standard cosmologies

Description: We discuss here the uncertainties in the nuclear input data relevant for calculations of standard and non-standard primordial nucleosynthesis. We show how these uncertainties can affect the predictive power of such calculations, and we identify those key nuclear reactions for which improved experimental data on the associated reaction rates is most needed. Such experimental data can lead to more accurate discriminatory tests between the differing primordial nucleosynthesis scenarios. 34 refs., … more

Summary of computational support and general documentation for computer code (GENTREE) used in Office of Nuclear Waste Isolation Pilot Salt Site Selection Project

Description: A Decision Tree Computer Model was adapted for the purposes of a Pilot Salt Site Selection Project conducted by the Office of Nuclear Waste Isolation (ONWI). A deterministic computer model was developed to structure the site selection problem with submodels reflecting the five major outcome categories (Cost, Safety, Delay, Environment, Community Impact) to be evaluated in the decision process. Time-saving modifications were made in the tree code as part of the effort. In addition, format change… more

Waste management strategy for nuclear fusion power systems from a regulatory perspective

Description: A waste management strategy for future nuclear fusion power systems is developed using existing regulatory methodology. The first step is the development of a reference fuel cycle. Next, the waste streams from such a facility are identified. Then a waste management system is defined to safely handle and dispose of these wastes. The future regulator must identify the decisions necessary to establish waste management performance criteria. The data base and methodologies necessary to make these de… more

Establishment and maintenance of a coal sample bank and data base

Description: Headspace oxygen contents of several designated drums containing {minus}l inch and {minus}{1/4} inch coal were measured. These measurements were later discontinued by agreement with the Project Manager, as the leakage of plastic drums and buckets has been well documented. During the current reporting period a total of 65 data printouts were distributed. In addition, 10 special data requests were fulfilled by either search/sort and printout or creation of a data disk, resulting in distribution o… more

Patterns of United States mortality for ten selected causes of death

Description: Income, ethnicity, education, and occupation are examples of socio-economic factors associated with the occurrence of disease, whether an investigation focuses on an individual or on an aggregation of individuals. In this study, data aggregated to the county level are used to explore two issues - geographic variation and geographic covariation of ten selected causes of death in the United States. The counties of the United States are characterized by 15 socio-economic variables and age-adjusted… more

Solar coal-gasification reactor with pyrolysis-gas recycle. [Patent application]

Description: Coal (or other carbonaceous matter, such as biomass) is converted into a product gas that is substantially free from hydrocarbons. The coal is fed into a solar reactor, and solar energy is directed into the reactor onto coal char, creating a gasification front and a pyrolysis front. A gasification zone is produced well above the coal level within the reactor. A pyrolysis zone is produced immediately above the coal level. Steam, injected into the reactor adjacent to the gasification zone, reacts… more

Harmonically excited orbital variations

Description: Rephrasing the equations of motion for orbital maneuvers in terms of Lagrangian generalized coordinates instead of Newtonian rectangular cartesian coordinates can make certain harmonic terms in the orbital angular momentum vector more readily apparent. In this formulation the equations of motion adopt the form of a damped harmonic oscillator when torques are applied to the orbit in a variationally prescribed manner. The frequencies of the oscillator equation are in some ways unexpected but can … more

Mechanical design criteria for continuously operating neutral beams

Description: Mechanical design criteria for high-energy neutral beam injectors capable of prolonged operation are examined. The generalized structural, heat transfer, and hydraulics equations are presented for convectively cooled grids. The effectiveness of helium, liquid sodium, and subcooled water for cooling a 2-mm-diameter, 8-m-long grid tube is shown. Cooling effectiveness is determined as a function of the number of tubes in series vs heat flux, where the number of tubes in series ranges from 1 to 100… more

Meteorological conditions during the winter validation study at Rocky Flats, Colorado: An overview

Description: The objective for the Winter Validation Study was to gather field data for validation of the Terrain-Responsive Atmospheric Code (TRAC) under winter time meteorological conditions. Twelve tracer tests were conducted during a two-week period in February 1991. Each test lasted 12 hours, with releases of SF{sub 6} tracer from the Rocky Flats Plant near Golden, Colorado. The tests included ground-based and airborne sampling to 16 km from the release point. This presentation summarizes meteorologica… more

Large-area sheet task advanced dendritic web growth development. Quarterly report, October 23, 1983-December 31, 1983

Description: Two types of design concepts were evaluated with the thermal models: (1) a vertical thermal element which modifies both the temperature profile in the web as well as the convective gas flow near the web; and (2) a thinner lid configuration in which the second lid is replaced by a hot cavity. Each involves trade-offs which need experimental evaluation. Residual stress measurements using the serial split-width technique indicated that the real residual stress was comparable to (or less than) the … more

The effect of chemical additives on the synthesis of ethanol

Description: The objective of this research was to investigate the reaction mechanism of higher alcohol and aldehyde synthesis from syngas and the role of additives in the synthesis. An in situ IR reaction system and probe molecule technique were developed to study adsorbed species, active sites, and reaction pathway during reaction. The catalysts used for this study included silica-supported Rh, Ru, and Ni. (VC)
