STUDY OF FAILURE MECHANISMS IN HIGH-POWER RADIO FREQUENCY GENERATING DEVICES.
Abstract
The aim of the investigation was 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. Medium-power X-band amplifiers were life-tested at a high duty factor and evaluated against tubes tested at a lower duty factor; a change in tube-processing appears to improve tube performance. Initial electrical and gas data are reported for other tube types. Gas ambient and sorption phenomena for oxide-coated cathode-anode subassemblies under operating conditions are presented. Application of the anode accelerating voltage causes desorption of hydrogen and hydrogenous gases; thus, the anode is a major source of hydrogen. (Author)
