Gyro peniotron forward wave oscillators

The pulse spreading of the forward propagating absolute instability in gyro-peniotron interaction can be utilized to provide the feedback mechanism for establishing forward wave oscillators. By properly choosing the interaction length and beam current, high efficiency stable output at high harmonic operation can be attained. This is demonstrated by performing computer simulations which also reveal that the peniotron interaction is able to suppress the gyrotron interaction and reaches the maximum efficiency despite the influence of the gyrotron mode.<
