High voltage analysis of electron gun for low power and high power gyrotron

摘要

The paper presents the high voltage analysis of Magnetron Injection Gun for 42 GHz, 200 kW and 120 GHz 1 MW gyrotrons. The Finite Element Analysis code TRAK has been used for the analysis of high voltage breakdown. In the analysis, the potential and electric field are estimated only at the critical regions between two electrodes, where the chance of voltage breakdown is prominent.
