Multimode Simulation of High Frequency Gyrotrons.
Abstract
This paper presents a simulation study of mode competition in highly overmoded gyrotron cavities. The parameters of the study have been selected to correspond to the approximate design parameters of a 280 GHz, 1 MW gyrotron at the Massachusetts Institute of Technology (MIT). The MIT gyrotron is designed to run in the TE+42,7 mode, using a 50 A, 84 keV electron beam, with a normalized beam radius of 0.6, and a beam alpha of 1.6. This study addresses 1) the problem of achieving gyrotron operation in the design mode, and at a value of magnetic detuning sufficient to achieve high efficiency operation, and 2) the mode purity of the final state.
