LIQUID METAL-HEATED SPACE RADIATOR-MOUNTED THERMIONIC GENERATOR. Quarterly Report No. 1, July 1-September 30, 1963

Description: The design of the thermionic converter to be evaluated was completed. The converter incorporates a tantalum-10% tungsten alloy liquid metal containment tube insulated by BeO from a tungsten-25% rhenium emitter. A nickel collector with an interelectrode space of 8 mils was selected. The predicted performance of this converter indicates a power output of 4.7 w/cm/sup 2/ with an efficiency of 12% when the emitter temperature is 1500 deg C. A bifilar tungsten filament was selected for use as a heater in this program based on a study contained in this report. (auth)
