LONG-LIFE COLD CATHODE STUDIES FOR CROSSED-FIELD TUBES
Abstract
A machined 6061 (97.5% purity) aluminum target, a machined 1100 (99. 0+% purity) aluminum target, and a 9500 A aluminum layer on copper target were each evaluated in the Electron Bombardment Vehicle for approximately 40 hours under high current density electron bombardment conditions, both with and without oxygen. Delta sub max varied between 1.5 and 2.5 for the two machined aluminum samples and between 1.5 and 2.8 for the evaporated aluminum target. Initial test processing of QKS1397 Model No. 8B with an aluminum cathode was performed and the tube awaits life test. The QKS1194 CFA test vehicle with impregnated tungsten emitter was tested for 10 hours. A life-test operating point at a one-megawatt power level was established and the tube is awaiting life test.
