Abstract

A self consistent and time dependent particle code has been used to simulate the transient effects of a high current gyrotron. At high beam currents, the output wave exhibits the effects of self-modulated oscillation and period doubling. In the regime of high injected signal powers, the locking bandwidth and time constant of high-power gyrotron phase locking simulations are observed to be respectively larger and smaller than the prediction from a lumped circuit theory. The multimode simulation of the risetime wave generation processes also demonstrates some nonlinear processes such as transient mode co-existence and mode suppression which appear to be of general interest and importance for short-pulse gyrotrons.
