Abstract

Results of designing of a sectioned metal oxide hot cathode with indirect heating and a total emission coating area of 100 cm2 are described. The design of the hot cathode enables control of the working surface temperature and allows one to change emission surface without replacing the whole hot cathode. The thermal test results are presented. The possibility is shown of applying the hot cathode in the uncharacteristic mode of gas discharge formation in medium vacuum conditions.
