Design and simulation of electron-optical system of sheet beam klystron

Design methods for periodic permanent magnet focusing system are presented. Using E-GUN, SUPERFISH, MAFIA, and PIC, 2D and 3D simulation platforms of electron-optical system with plane symmetry are established, and the electron-optical system is X-band 100 MW sheet beam klystron is designed and simulated. The simulation result shows that the beam transmission is 99.6% in a 600 mm propogation distance when the period of the magnetic field is 60 mm, and the magnetic field intensity of the entrance is 0.1 T.
