Abstract
We present simulation results from the code MAGY of a 110 GHz, 1.5 MW gyrotron which is currently in short pulse operation at MIT. The experimental peak power is 1.44 MW at 37 % efficiency, when operating in the TE/sub 22,6/ mode, with a velocity ratio (v/sub /spl perp///v/sub /spl par//) of 1.43. The MAGY simulations are done for triplet mode excitation (TE/sub 21,6/, TE/sub 22,6/ and TE/sub 23,6/), and include both velocity spread and the azimuthal nonuniform charge density of the electron beam. For a velocity spread of 5.5 % and the measured value of beam emission nonuniformity, the MAGY simulations are in good agreement with the measured experimental results.
