Description
This paper describes the design progress of the electron gun, and solenoid of 50 MW class klystron at C-band frequency (5720 MHz) for CEPC LINAC. The beam optics is designed in DGUN code for a space charge beam current of 318 A at an acceleration potential of 350 kV with average cathode loading of less than 6.0 A/cm^2. The maximum surface electric field at the beam optics and high voltage ceramic seal is reduced to be less than 18.65 kV/mm and 3.81 kV/mm, respectively. The magnet design transports the beam with low scalloping parameter less than 5.0 % with laminar flow downstream. Gun envelop and magnetic field are designed in POISSON code.3-D CST simulation is under progress for validation of 2D simulation results.
