1.5 megawatt dc chopper power supplies for plasma shape control on Doublet III

Description: The Doublet III device is designed to study noncircular plasmas, including doublet and dee-shaped cross-sections. The plasma shape is determined by a system of 24 field-shaping coils which surround the vacuum vessel. Control of the magnetic flux linking these coils allows the plasma shape to be varied and controlled. This paper describes the high-speed dc chopper which is a major component of the field-shaping coil power system. The high-speed dc choppers, with a frequency response of up to 5 k… more

2 meg-ampere prototype levitated coil for multipole fusion

Description: The coils major diameter is 1.0 meter and it occupies a cross-section which is about 0.2 meter minor in diameter. The prototype coil will carry four times the current of the largest such magnet built to date. As a result, the peak induction in the coil is about 8 T and the stored magnetic energy will be around 3 MJ. The paper describes the proposed Nb/sub 3/SN superconductor, the quench protection system which is based on the LBL shorted secondary concept, the isochroic refrigeration storage sy… more

24-MW neutral-beam injector of 400-keV H/sup 0/

Description: The negative and positive ion systems have both common goals and common problems. In fact, we have identified five items that must be developed before any large, neutral-beam injector, operating continuously or almost so, can be engineered. The five items are: (1) a continuous or almost continuous ion source, with 1A designating a source of positive ions and 1B a direct extraction source of negatives, (2) a recirculating metal-vapor cell, (3) a computer code with which to calculate beam traject… more

1979 breeding bird censuses and summary of 1977-1979 results

Description: As part of a program to characterize the plant and animal life of the Laboratory site and the surrounding region, the two breeding bird censuses originated in 1977 were continued in 1979. Twelve census trips were made to the BNL plot and 10 to the Westhampton plot by seven volunteer observers. Comparisons of data from the three years showed that the number of territorial males on the BNL plot did not change significantly, but the number of breeding species showed a continuous decline, from 18 t… more

Aerial gamma ray and magnetic survey: Raton Basin Project. The Raton and Santa Fe Quadrangles of New Mexico. Final report

Description: In 1978, EG and G geoMetrics collected 4955 line miles of high sensitivity airborne radiometric and magnetic data in New Mexico within the Raton and Santa Fe quadrangles. These quadrangles represent part of the Raton Basin Project. All radiometric and magnetic data for the two quadrangles were fully reduced and interpreted by geoMetrics, and are presented as three volumes; one Volume I covering both quadrangles and separate Volume II's for the individual quadrangles. Over 50% of the survey area… more

Aerosol measurement techniques and accuracy in the CSTF. [LMFBR]

Description: The Containment Systems Test Facility (CSTF) provides the capability of performing large-scale aerosol behavior experiments at a scale factor of approximately 0.5 in height for a typical reactor containment building. The containment height is 20.3 m, the volume is 850 m/sup 3/, the design pressure is 5 bar, and quantities of sodium up to 1250 kg can be sprayed or spilled for sodium combustion product aerosol sources. Instrumentation is provided for characterization of the aerosol and the contai… more

Aerosol sampling and characterization for hazard evaluation. Progress report, October 1, 1977-September 30, 1978. [/sup 239/Pu aerosol monitor performance in work area]

Description: Measurements of the dilution of air contaminants between worker breathing zone and area air samplers were made by releasing a test fluorescent aerosol in workrooms equipped with aerosol surveillance systems. These data were used to evaluate performance and suggest improvements in design of alarming air monitor systems. In one workroom studied, average half-hour breathing zone air concentration needed to trigger alarm was found to be 960 times the maximum permissible air concentration for occupa… more

Air quality impacts of a coal-fired power plant in the Upper Cook Inlet of Alaska

Description: Air quality impacts for a proposed 500-MWe power plant in the Upper Cook Inlet are analyzed using screening-level models as a means to study coal development in Alaska. Simulation cases were run that examined impacts of controls on sulfur dioxide emissions. Results indicated that the highest concentrations of sulfur dioxide occur for the uncontrolled case whereas lower plume rise causes maximum concentrations of nitrogen dioxide and total suspended particulates when sulfur dioxide emissions con… more

Air-sea interaction experiments (1976) at an offshore platform near Atlantic City, New Jersey

Description: Air-sea interaction experiments conducted at an offshore platform near Atlantic City, New Jersey, during September 14-23, 1976, are described in this report. Momentum flux was measured by the eddy correlation method. Wave height, slope, and direction spectra were estimated from wave height variations measured by an array of wave staffs positioned in the corners of an equilateral triangle. Some preliminary results of the analysis are also presented.

Alternate laser fusion drivers

Description: Over the past few years, several laser systems have been considered as possible laser fusion drivers. Recently, there has been an increasing effort to evaluate these systems in terms of a reactor driver application. The specifications for such a system have become firmer and generally more restrictive. Several of the promising candidates such as the group VI laser, the metal vapor excimers and some solid state lasers can be eliminated on the basis of inefficiency. New solid state systems may im… more

Alternate laser fusion drivers

Description: One objective of research on inertial confinement fusion is the development of a power generating system based on this concept. Realization of this goal will depend on the availability of a suitable laser or other system to drive the power plant. The primary laser systems used for laser fusion research, Nd/sup 3 +/: Glass and CO/sub 2/, have characteristics which may preclude their use for this application. Glass lasers are presently perceived to be incapable of sufficiently high average power … more
