SINGLE-CRYSTAL THERMIONIC CONVERTER STUDIES

Abstract

A thermionic converter is described in which the emitter is made of a single crystal of tungsten which has been cut to expose 16 square centim eters of 110 surface. Details of the cathode surface preparation, anode construction, and assembly techniques are presented along with some operating characteristics from the first successful run. The output power was not as large as expected. A second run following re processing demonstrated improved performance particularly at low cesium pressures.
