Abstract

A double anode magnetron injected gun (MIG) for a terahertz (THz) band cyclotron oscillation tube has been presented in this paper. Through design, simulation and optimization by the particle-in-cell (PIC) code, a double-anode electron gun with trans-velocity spread of 3.19% is obtained, and the ratio of the transverse velocity to the axial velocity is equal to 1.4. The designed electron gun well satisfies the requirement of the 0.4 THz gyrotron.
