Results of analysis and design studies accomplished on one-loop and two- loop thermionic radiator-generator systems and the two-loop thermionic heat exchangergenerator are described. An extensive compilation of measured thermionic converter emission data at emitter temperatures of 1100, 1200, 1300, and 1400 deg C was prepared for a plandar converter consisting of a molybdenum emitter andd nickel collector with a 5-mil gap. These data were experimentally optimized with respect to cesium and collector temperatures, and were used to calculate parametric efficiencies and actual power densities for the cylindrical thermionic radiator and heat exchanger converter designs. An overall evaluation of the design and fabrication problems, system weight and performance, reliability, operational factors and growth potential, resulted in the conclusion that the heat exchanger location for mounting thermionic converters offers considerably more promise than the radiator location.
