Paper Abstract

An electron magnetron-injection gun (MIG) for a high-power relativistic gyrotron has been modeled numerically. The influence of the electrons locked in a trap between the cathode and the working space on the beam parameters has been analyzed. It is proposed to remove such electrons by means of a special diaphragm installed at the beginning of the transportation channel, which makes it possible to increase the pitch-factor and reduce the velocity spread of the formed helical electron beam.
