A slow-time-scale single-mode simulation and a fast-time- scale multimode particle code have been used to simulate the transient behavior in a pulse-line-driven high peak power gyrotron oscillator. Both slow- and fast-time-scale single-mode simulations are found to be in good general agreement with the fast-rise-time wave generation processes theorized in an earlier experiment, while some discrepancies are found between the fast-time-scale multimode simulations and the experimental observations. The multimode simulation points out the possibility of transient mode suppression and mode competition processes which appear to be of general interest for short-pulse gyrotrons.
