Long-Life Cold Cathode Studies for Crossed-Field Tubes

Abstract

Tests were continued on the effects of high current-density electron bombardment (0.75 A/sq cm) and of residual gases (O2, N2, and CO2) on the secondary emission ratio in the Electron Bombardment Vehicle (EBV). Four samples were tested during the present report period, two anodized Be samples, one electron-beam-evaporated aluminum-oxide on molybdenum sample and one naturally oxidized beryllium sample.
