STUDY OF FAILURE MECHANISMS IN HIGH-POWER RADIO FREQUENCY GENERATING DEVICES.

Abstract

The aim of this ivestigation is to determine failure mechanisms caused by residual gases in traveling-wave tubes and to study means of eliminating these gases in order to improve tube reliability. Gas spectra and electrical test data are shown for one tube operating at a severe life-test condition; correlation is made with tubes operating under a lower duty cycle. Gas ambient and gas sorption phenomena for tube components under operating conditions are presented for uncoated-cathode subassemblies and an oxide-coated cathode subassembly. In these subassemblies, the heater filament is the major gas source. (Author)
