Abstract :
A new phenomenon in the gyrotron traveling-wave amplifier (gyro-TWT) in the form of nonlinearly driven oscillations was reported. A zero-drive stable gyro-TWT is shown to be susceptible to considerably reduced dynamic range at the band edge, followed by a sudden transition into driven oscillations, and then a hysteresis effect. An analysis of this unexpected behavior and its physical interpretation are presented.
