3D-Design of Magnetron Injection Gun for 42GHz Second Harmonic Gyrotron

This paper presents the 3D design simulation of MIG for 42GHz, 100kW second harmonic Gyrotron operating at TE
0.3
mode. Initially, the analytical design approach was opted using design trade-off equations and then the 3D simulation has been performed by using CST Particle Studio. The beam parameters, velocity ratio, and velocity spread was obtained 1.35, 3.3% respectively.
