PLANAR CONVERTERS FOR RADIOISOTOPE GENERATORS.
Abstract
Work is reported on the development of planar thermionic converters for radioisotope generators. Specific tasks under this program include investigations of the feasibility of a dynamic cesium flow system (Integral Cesium Reservoir), and the development and evaluation of single-crystal tungsten emitters incorporated in planar thermionic converters. Efforts during the reporting period included the fabrication, test and evaluation of the Integral Cesium Reservoir(ICR). These tests demonstrated the feasibility of the ICR and indicated a definite reduction in the dependence of the converter pressure on the reservoir temperature. Two planar thermionic converters (500-HP-1 and 500-HP-2) were subjected to life test performance evaluation, including emitter and collector work function measurements. Both converters employ single-crystal(110) tungsten emitters operating at 2000 K.
