90-PERCENT TO 93-PERCENT EFFICIENT COLLECTOR FOR OPERATION OF A DUAL-MODE TRAVELING-WAVE TUBE IN THE LINEAR REGION

An axisymmetric multistage depressed collector was evaluated in conjunction with a dual-mode TWT. Collector performance optimizations for the TWT operation in the linear range were stressed, Measured collector efficiencies in excess of 90 percent led to dramatic improvements in TWT overall efficiency.
