Abstract According to a set of analytic equations based on adiabatic compression theory and angular momentum conservation, a single-anode Magnetron Injection Gun(MIG) with a nose-shape accessorial focus pole is studied in this paper. The parameters of the single-anode MIG are optimized through computer simulation with an electron trajectory code (EGUN—226). The effect of the ratio of transverse velocity and longitudinal velocity α on axial velocity spread is analyzed, which shows that a high-quality electron beam with large α and low axial velocity spread can be realized for large current application.
