Field-reversal experiments in the mirror fusion test facility (MFTF)

Description: Detailed consideration of several aspects of a field-reversal experiment was begun in the Mirror Fusion Test Facility (MFTF): Model calculations have provided some plausible parameters for a field-reversed deuterium plasma in the MFTF, and a buildup calculation indicates that the MFTF neutral-beam system is marginally sufficient to achieve field reversal by neutral injection alone. However, the many uncertainties indicate the need for further research and development on alternate buildup method… more

Advanced direct coal liquefaction. Quarterly technical progress report No. 1, September-November 1983

Description: Wyoming subbituminous coal was liquefied using three different two-stage process configurations in bench-scale tests. These process configurations differed in the type of fractionated deashing resid being recycled to the individual stages. The objective of these runs was to determine whether, by recycle of specific resid streams to the thermal stage, the second stage catalyst life could be improved without detrimentally affecting distillate yield or hydrogen consumption. The results indicate th… more

Development of magnetic mirror systems for nuclear testing applications

Description: Several system studies have concluded that the small size and steady state nature of magnetic mirror systems provide attractive features for nuclear-testing applications. The principle shortcoming of mirror systems is their small data base relative to that of tokamaks. This paper summarizes the present data base and describes experiments that could be carried out with small modifications of existing facilities to explore plasma physics issues associated with the production of high neutron fluxe… more

Suppression of transverse beam breakup modes in an induction accelerator by gas focusing

Description: The effect of beam-generated positive ions on the beam-breakup instability in linear electron accelerators is calculated using simple models. The strongly nonlinear dependence of the ion focusing force on radius makes a complete suppression of the mode growth possible, in contrast to solenoidal focusing. The predicted gas pressures for significant stabilization of the mode growth in a machine configuration like ATA is relatively low (10/sup -5/ to 10/sup -4/ torr), even for high-Q modes.

An MS-DOS-based program for analyzing plutonium gamma-ray spectra

Description: A plutonium gamma-ray analysis system that operates on MS-DOS-based computers has been developed for the International Atomic Energy Agency (IAEA) to perform in-field analysis of plutonium gamma-ray spectra for plutonium isotopics. The program titled IAEAPU consists of three separate applications: a data-transfer application for transferring spectral data from a CICERO multichannel analyzer to a binary data file, a data-analysis application to analyze plutonium gamma-ray spectra, for plutonium … more

Cost effectiveness of long life incandescent lamps and energy buttons

Description: Long-life replacement lamps for the incandescent lamp have been evaluated with regard to their cost effectiveness. The replacements include the use of energy buttons that extend lamp life as well as an adaptive fluorescent circline lamp that will fit into existing incandescent lamp sockets. The initial, operating, and replacement costs for one million lumen hours are determined for each lamp system. It is found that the most important component lighting cost is the operating cost. Using lamps t… more

Evaluation of selected chemical processes for production of low-cost silicon: Phase III. Silicon Material Task, Low-Cost Solar Array Project. Sixteenth/seventeenth quarterly progress report, July-December 31, 1979

Description: The method under development for the production of semiconductor grade silicon is based on the zinc vapor reduction of silicon tetrachloride in a fluidized bed of seed particles. Construction of the PDU was completed during the report period, the fluidized-bed reactor was coated internally with silicon/SiC, and the operation of several systems was checked out. However, problems with the zinc feed system, unrelated to its basic operability, delayed introduction of zinc vapor to the PDU. At the e… more

450/sup 0/F step transient thermal analysis of the LOFT pressurizer surge and spray line piping

Description: The LOFT pressurizer spray and surge line piping was analyzed for a 450/sup 0/F step change in fluid temperature. This transient was chosen to conservatively represent several pressurizer operating transients that had not previously been analyzed. These include temperature transients resulting from a 300/sup 0/F ..delta..T between pressurizer temperature and cold leg temperature, injection of a cooled (70/sup 0/F) slug of stagnant fluid into the hot (540/sup 0/F) spray line piping, and inflow o… more
