Abstract :
A detailed theoretical study of the absolute instabilities in a TE 01-mode, fundamental cyclotron harmonic gyro-TWT with distributed wall losses has resulted in a "roadmap" for the design of an ultrahigh gain, stable W-band gyro-TWT. Although still being optimized, a tube built using these design principles has already yielded 140 kW peak output at 22% efficiency with 61 dB gain
