Practical Aspects of Fundamental Research in Thermionic Conversion.

Abstract

The report summarizes the results of the past year in a continuing effort to utilize basic converter research for practical improvement of engineering designs. Experimental results are presented which were obtained with an argon discharge used as an experimental analog for a cesium vapor system. Attempts to suppress the power lost in the arc voltage drop are described. An auxilliary discharge triode was investigated in the argon system. A more extensive study of arc drop suppression by pulse enhancement was carried out for both argon and cesium diodes. A theoretical correlation is presented which allows the emitter temperature in a converter to be determined from the J-V characteristic. An analytical description of the adsorption phenomenology for cesium and oxygen on tungsten is presented. The features of the analysis are generally applicable to adsorbate-substrate systems with both monatomic and diatomic molecules. (Author)
