Abstract

We present simulation result of an MIG electron gun for a 0.4 THz, 100 kW gyrotron. The gyrotron is a device to generate very high power at very high frequencies. The magnetron injection gun (MIG) is a critical component in the gyrotron[1]. The design study of the MIG electron gun has been done by three different simulation codes. The EGUN code for 2D has been used for the initial geometry optimization with a 70 kV and 13 A of the electron beam. The MICHELLE code and the CST Particle Studio have been also used and results are compared.
