Abstract
This paper reports the results about a Magnetron Injection Gun(MIG) designed recently. This gun can work at frequency 94GHz for gyrostron. After lots of optimizings and simulations about the structure, at the coefficient of magnetic field 0.8313(3.5755T), beam voltage 24KV, and beam current 2A, it was observed that the electron ratio 1.4, the maximum transverse velocity spread less than 2.7%, the longitudinal velocity about 5.7%. The gun was used for a 94GHz gyrotron, it was obtained that the output power of about 25KW with efficiency 53%(SDC).
