Abstract

When simulating double-beam magnetron injection gun using EGUN and MAGIC

electromagnetic coils was used to match magnetic field of magnetron injection gun.Least square method was used to calculate parameters of electromagnetic coils

which was used to match magnetic field of magnetron injection gun.When simulating 34GHz double-beam magnetron injection gun

the parameters of electromagnetic coils were calculated by least square method.The result of simulation shows that least square method can calculate parameters of solenoid magnets and a 34GHz double-beam magnetron injection gun with a modest velocity ratio of the beam and a low velocity spread was designed.
