Design and Simulation of Electron Gun and Focusing System for High Power Space TWT

A low Perveance Electron Gun with two anodes has been designed and simulated for high power Ku-band space traveling wave tube (TWT). A convergent pierce type electron gun is designed using commercial softwares EGUN and CST-PS. The focusing system is designed using periodic permanent magnet (PPM) with confined flow technique in Magfld-EGUN and CST-PS.
