Requirements for signal cables and off-line data processing

Description: The number and types of cables for various experiments planned for the ISABELLE storage rings are estimated, and the results of a questionnaire on anticipated data taking rates are discussed. Necessary data acquisition rates, data storage capabilities, and data processing rates are estimated. (PMA)

Technology of mirror machines: LLL facilities for magnetic mirror fusion experiments

Description: Significant progress in plasma confinement and temperature has been achieved in the 2XIIB facility at Livermore. These encouraging results, and their theoretical corroboration, have provided a firm basis for the design of a new generation of magnetic mirror experiments, adding support to the mirror concept of a fusion reactor. Two new mirror experiments have been proposed to succeed the currently operating 2XIIB facility. The first of these called TMX (Tandem Mirror Experiment) has been approve… more

Microcomputer-based pellet trajectory guidance system for the Baseball II-T experiment

Description: In the Baseball II-T experiment a pellet generation and injection system was employed to place frozen ammonia pellets at the focus of a laser beam. The original trajectory guidance system suffered a number of problems that limited its accuracy and complicated the operation of the system. These problems were related to variable charge-to-mass ratios, timing, pellet discrimination, and computer speed. The original system design was improved by changes to the sensing components, microcomputer, and… more

Tandem mirror reactor

Description: A parametric analysis and a preliminary conceptual design for a 1000 MWe Tandem Mirror Reactor (TMR) are described. The concept is sufficiently attractive to encourage further work, both for a pure fusion TMR and a low technology TMR Fusion-Fission Hybrid.

Efficient production of neutral beams by photodetachment of negative ions

Description: A neutral fraction approaching 97 percent can be attained by photodetachment of negative ions if the photon density and thickness are adequate. This high efficiency of neutralization is desirable not only because of the improvement in power balance and power efficiency but also because of the increase in the useable beam current per module. Only modest improvements in commercial solid-state lasers are required to fulfill the requirements of a photodetachment cell for a fusion reactor. The wavel… more

Computer simulation of the Charpy V-notch toughness test

Description: The dynamic Charpy V-notch test was simulated on a computer. The calculational models (for A-533 Grade B class 1 steel) used both a rounded and a flat-tipped striker. The notch stress/strain state was found to be independent of the three-point loading type and was most strongly correlated with notch-opening displacement. The dynamic stress/strain state at the time of fracture initiation was obtained by comparing the calculated deformed shape with that obtained in interrupted Charpy V-notch test… more

Luminescence studies of oxygen absorption on thorium

Description: The interaction of oxygen with a thorium metal surface is being studied by monitoring the luminescence of thorium in an electron beam. By combining luminescence measurements with Auger electron spectroscopy data, it is possible to distinguish between processes that depend upon the oxygen pressure at the sample surface, and those that depend only upon the amount of adsorbed oxygen.

Experimental laser fusion devices and related vacuum problems

Description: Laser fusion experiments require hard vacuum in the laser-beam spatial filters, target chambers and for target diagnostics instruments. Laser focusing lenses and windows, and target alignment windows must hold vacuum without optical distortion, and must be protected from target debris. The vacuum must be sufficient to prevent residual gas breakdown in focused laser light, avoid arcing at high voltage terminals, minimize contamination and melting of cryogenic targets, and prevent adsorption of t… more

Proceedings of the Workshop on Geothermal Reservoir Engineering: 1977

Description: The Third Workshop on Geothermal Reservoir Engineering convened at Stanford University on December 14, 1977, with 104 attendees from six nations. In keeping with the recommendations expressed by the participants at the Second Workshop, the format of the Workshop was retained, with three days of technical sessions devoted to reservoir physics, well and reservoir testing, field development, and mathematical modeling of geothermal reservoirs. The program presented 33 technical papers, summaries of… more
