Numerical Simulation of Single-anode and Double-anode Magnetron Injection Guns for 127.5 GHz 1MW Gyrotron

摘要

This paper presents the design of two types of magnetron injection guns (MIG's) for 1MW, 127.5 GHz gyrotron. TE243 mode has been chosen as the operating mode. In-house developed code MIGSYN has been used to estimate the initial gun parameters. The electron trajectory tracing program EGUN and in-house developed code MI-GANS have been used to optimize the single-anode and the double-anode design for 80 kV, 40 A MIG. The parametric analysis of MIG has also been presented. The advantages and the disadvantages of each kind of configuration have been critically examined.
