Abstract :
A MIG double-beam gun is presented. The double-beam gun has two annular emitters. When the two beams are injected into the RF system, they can interact with the same mode distribution. The performance of the double-beam Magnetron Injection Gun(MIG) is studied with the particle-in-cell(PIC) code MIGIC for application 35GHz double-beam coaxial gyrotron. In this paper, MIG provide two 70kv, 10Amp beam with the velocity ratio 1.5. Minimum of the transverse velocity spread and the axial velocity spread is about 3%, 5% respectively.
