  • Solid Thermionic Cathode (AREA)

Abstract

PURPOSE: In the hot-cathode, the thermion emitting powder is used which the highmelting point metal adheres to by evaporation or sputtering to constitute the high-current density hot-cathode, so that the cathode of low power consumption can be obtained.
