Abstract

To develop 200GHz electron cyclotron maser (ECM) in University of Electronic Science and Technology of China, a magnetron injection gun (MIG) with 60kV/5A has been designed. The behavior of the designed magnetron injection gun with variations of relevant parameters is given in detail by means of computer simulations. The preliminary and operation parameters of the gun are reported. The optimization by using the EGUN code shows that the ratio of the perpendicular velocity to the parallel velocity of the electron beam is 1.63, and the perpendicular and parallel velocities spread are 2.62% and 6.63%, respectively.
