Design of MIG for 42GHz, 200kW Gyrotron

A triode type magnetron injection gun (MIG) shown in Fig. 1 for a 200 kW, 42 GHz gyrotron has been designed. Operating voltage of modulating anode is 29 KV and accelerating voltage is 65 KV. Operation mode of this gyrotron is TE03 and it would be used in a TOKAMAK system for plasma heating. This MIG is designed by using commercially available code EGUN and three in house developed software code MIGSYN, GINTMESH and MIGANS respectively.
