LOW TEMPERATURE THERMIONIC CONVERTERS

Abstract

Fabrication and development work performed on the investigation of low temperature thermionic converters are presented. The fabrication work included a high temperature metal-ceramic electron gun envelope, improvement in emitter brazing techniques and anode cooling techniques. Improved anode temperature uniformity was achieved with a gas cooling loop shaped in the form of a pancake helix. Mo or Cu powder improved the heat transfer between the helix and cup bottom. Cell processing and evaluation data is given as well as results of destructive and shock tests. Techniques for solar and nuclear simulation are discussed.
