INVESTIGATION OF VARIOUS ACTIVATOR REFRACTORY SUBSTRATE COMBINATIONS.

Abstract

A study was made of various thin film activatorrefractory substrate combinations with emphasis on the determination of evaporation of the activator material under various temperature and operation conditions. The purpose of this program was twofold: (1) to determine the properties of new materials combinations capable of producing high emission density and long life from a thermionic cathode, and (2) to investigate the effects of various gases upon the thermionic emission.
