INVESTIGATION OF THERMIONIC CONVERTER OPERATING WITH A HIGH TEMPERATURE COLLECTOR.

Abstract

The work carried out with the uncooled collector converter was the following: (1) measurement of electrode work functions in vacuo; (2) thermal calibration of the emitter in vacuo; (3) thermal calibration of the emitter in cesium vapor; (4) measurement of current-voltage characteristics and converter efficiencies for a variety of electrode temperatures, electrode spacings, and cesium vapor measures; (5) assemble the cooled collector converter with the new NaK cooled collector. In addition, it was found necessary to do two other calibrations concerned with accurate measurement of the electrode temperatures. One of these calibrations had to do with a reflection effect which resulted in the observed electrode temperatures being higher than their actual values. The second calibration had to do with light absorption in cesium vapor at high pressure.
