Compact 36 kJ electron beam system for laser pumping (open access)

Compact 36 kJ electron beam system for laser pumping

An electron beam machine consisting of six modules is being constructed for the 'B' amplifier of the RAPIER KrF laser system. Each module consists of a diode, a 5 ..cap omega.. positive charged water dielectric Blumlein pulse-forming line, and a five stage Marx generator. Separate 25 cm x 41 cm electron beams are formed in magnetically isolated diodes which when arranged in groups of three produce two nearly continuous 25 cm x 125 cm beams that enter the laser cell from opposite sides. The pulse-forming lines operate at 450 keV and produce 150 ns long pulses. The lines employ electrically triggered annular SF/sub 6/ output switches. The two concentric transmission lines of each pulse-forming line are charged in 1 ..mu..s through symmetric circuits to reduce diode prepulse voltage. The six modules together with the laser cell will occupy less than 15 m/sup 2/ of floor space.

Geothermal well-field and power-plant investment-decision analysis (open access)

Geothermal well-field and power-plant investment-decision analysis

Investment decisions pertaining to hydrothermal well fields and electric power plants are analyzed. Geothermal investment decision models were developed which, when coupled to a site-specific stochastic cash flow model, estimate the conditional probability of a positive decision to invest in the development of geothermal resource areas. Quantitative decision models have been developed for each major category of investor currently involved in the hydrothermal projects. These categories include: large, diversified energy resource corporations; independently operating resource firms; investor-owned electric utilities; municipal electric utilities; state-run resource agencies; and private third-party power plant investors. The geothermal cash flow, the investment decision analysis, and an example of model application for assessing the likely development of geothermal resource areas are described. The sensitivity of this investment behavior to federal incentives and research goals is also analyzed and discussed.

Experiments in magnetic switching (open access)

Experiments in magnetic switching

Magnetic switching offers an alternative to overcoming the rep-rate and life limitations of the spark gaps in the ETA/ATA induction accelerators. The principle has been applied for many years to radar modulators but at much lower power levels and longer pulse lengths. Comparatively recent developments in magnetic materials together with some optimal circuits have made it possible to go well beyond the state of the art. A magnetic modulator has been built which steps up and compresses a 25 kV, 5 ..mu..s pulse into a 250 kV, 50 ns pulse. A second magnetic modulator has been built and installed to replace four Blumleins and spark gaps in order to provide triggers for the complete ETA injector and accelerator. The paper outlines some practical and theoretical considerations affecting the design of the magnetic pulse generator.

Large-area silicon sheet by EFG. First quarterly report, January 1, 1981-March 31, 1981

A multiple growth run with three 10 cm cartridges was carried out with the best throughput rates and time percentage of simultaneous three-ribbon growth achieved to date in this system. Growth speeds were between 3.2 and 3.6 cm/minute on all three cartridges and simultaneous full-width growth of three ribbons was achieved 47% of the time over the eight-hour duration of the experiment. Improvements in instrumentation and in the main zone temperature uniformity have been two factors that have led to more reproducible growth conditions in the multiple ribbon furnace. Factors influencing ribbon quality are being investigated through the study of the effect of ambient gas species and concentrations on material properties. Growth of ribbon with the cold shoes characteristic of the high-speed systems has shown that the properties of this ribbon respond to ambient changes in much the same way as when no cold shoes are present. The best cell efficiencies attained for 10 cm wide ribbon grown with cold shoes are still below those obtained without cold shoes (10 to 11% versus 12 to 13%, respectively). It has also been shown in these experiments that meniscus CO/sub 2/ and quartz introduced in the melt (contained in graphite crucibles) are …

Method and apparatus for injecting a substance into the bloodstream of a subject

An apparatus and method for injecting a substance, such as a radiopharmaceutical, into the bloodstream of a subject is described. The apparatus comprises an injection means, such as a servo controlled syringe, a means for measuring the concentration of that substance in the subject's bloodstream, and means for controlling the injection in response to the measurement so that the concentration of the substance follows a predetermined function of time. The apparatus of the subject invention functions to inject a substance into a subject's bloodstream at a rate controlled by an error signal proportional to the difference between the concentration of the substance in the subject's bloodstream and the predetermined function.

Production of super-smooth articles

Super-smooth rounded or formed articles made of thermoplastic materials including various poly(methyl methacrylate) or acrylonitrile-butadiene-styrene copolymers are produced by immersing the articles into a bath, the composition of which is slowly changed with time. The starting composition of the bath is made up of at least one solvent for the polymer and a diluent made up of at least one nonsolvent for the polymer and optional materials which are soluble in the bath. The resulting extremely smooth articles are useful as mandrels for laser fusion and should be useful for a wide variety of other purposes, for example lenses.

Protected air-cooled condenser for the Clinch River Breeder Reactor Plant (open access)

Protected air-cooled condenser for the Clinch River Breeder Reactor Plant

The long term residual heat removal for the Clinch River Breeder Reactor Plant (CRBRP) is accomplished through the use of three protected air-cooled condensers (PACC's) each rated at 15M/sub t/ following a normal or emergency shutdown of the reactor. Steam is condensed by forcing air over the finned and coiled condenser tubes located above the steam drums. The steam flow is by natural convection. It is drawn to the PACC tube bundle for the steam drum by the lower pressure region in the tube bundle created from the condensing action. The concept of the tube bundle employs a unique patented configuration which has been commercially available through CONSECO Inc. of Medfore, Wisconsin. The concept provides semi-parallel flow that minimizes subcooling and reduces steam/condensate flow instabilities that have been observed on other similar heat transfer equipment such as moisture separator reheaters (MSRS). The improved flow stability will reduce temperature cycling and associated mechanical fatigue. The PACC is being designed to operate during and following the design basis earthquake, depressurization from the design basis tornado and is housed in protective building enclosure which is also designed to withstand the above mentioned events.
