THE DEVELOPMENT OF AN AUXILIARY ELECTRODE THERMIONIC CONVERTER

Abstract

Progress is reported on research conducted to improve the efficiency and life expectancy of thermionic energy converters for space applications. The program has been modified to the development of a cylindrical converter, the emitter of which is thermally bonded to but electrically insulated from a central heat-source tubing carrying liquid metal. Significant progress has been achieved in the various portions of the program. A particular geometry employing the Cross Current Converter principle was selected and the overall design has been determined. Two promising methods for the application of the emitter insulation are being evaluated. The effects of cesium on ceramics at the various temperatures of interest were observed and the results analyzed.
