Tungsten Thermionic Emission as a Gauge for Low Pressures of Cesium Vapor
Heated metal filaments under electric fields and low pressures of alkali metal gas eject electrons by thermionic emission as a function of the pressure of the gas and the temperature of the filament. To explore this process in a program to develop large-area alkali metal photocathodes, we have desig...
