HIGH-RESOLUTION LIQUID-FILLED MULTI-WIRE CHAMBERS FOR USE INHIGH-ENERGY BEAMS

Description: The authors describe experiments with liquid-xenon-filled wire chambers operating in the proportional mode and the difficulty of achieving useful gain when the anode wires have a spacing < 1 mm. As a result, they have largely turned our attention to chambers with closely spaced wires operated in the ionization mode. They have previously demonstrated a spatial resolution of 15 {micro} rms in this mode, using a 5-wire chamber and a collimated alpha source. They describe the construction of two… more

Effect of a bridge balance network on a semiconductor pressure transducer

Description: Pressure transducers and accelerometers that make use of semiconductors strain gages or have strain gages diffused on a silicon diaphragm cannot be used with a bridge balance network if one wants to achieve thermal zero compensation. Thermal zero compensation is compensating for the change in output due to temperature only, and is typically +-1.5 percent of the full scale output for a temperature change of 100/sup 0/F. The reason for not using a balance network is the way in which the transduce… more

The deposition of particulates in air sampling tubes

Description: An investigation was performed to define particulate deposition in exhaust air sampling tubes for plutonium areas. Twelve sampling tubes were washed with nitric acid. Residues from wash solutions were counted for total alpha activity. Results indicate negligible sample loss due to particulate deposition in sample delivery tubes.

Design for Krypton-85 Enrichment by Thermal Diffusion

Description: Substantial quantities of krypton having a krypton-85 concentration of less than 10% will become available if nuclear fuel-processing plants are required to collect the gaseous fission products rather than releasing them into the atmosphere. A modular thermal diffusion unit was designed for the enrichment of the krypton-85 to useful concentrations of greater than 45%. The design emphasizes reliability and integrity by incorporating no moving parts within the unit. The modular design also offers… more

Baseline Gas Turbine Development Program Second Quaterly Progress Report

Description: Progress is reported for a program to demonstrate by 1976 an experimental gas turbine powered automobile which meets the 1976 Federal Emissions standards and which is competitive in fuel economy, performance, reliability, and potential manufacturing cost with the conventional piston engine powered, standard size American automobile. Procurement delays have caused engine deliveries to slip one to two months. Assembly of Engine 3 with special instrumentation for NASA and Engine 4 to be used in th… more

Evaluation of the Effects of Geothermal Reservoir Fluid Temperature on the Costs of Steam Production and Power Generation

Description: This report provides a preliminary evaluation of the effect of reservoir temperatures on the cost of geothermal hot water wells and flash-steam gathering systems to support a 50,000 kW power plant. Comparisons are made of the capital investments required for each case and the corresponding payout period based on steam costs of 6 mill/kWh of power generated. In order to show how the reservoir temperatures and steam cost affect the cost of electric power delivered to the high tension bus at the p… more
