Observation of Mode Competition in an 11.4-GHZ Magnicon Amplifier

Abstract

This paper describes the observation of pulse shortening in an 11.4-GHz magnicon amplifier due to competition with a parasitic gyrotron mode. The parasitic mode occurred only at high operating powers, when the beam transverse momentum was high, and its excitation caused the power in the output pulse to fall off substantially. We analyze the competition between the gyrotron and magnicon modes using a time-dependent multimode gyrotron simulation code that has been specially modified to model synchronous magnicon as well as nonsynchronous gyrotron interactions.
