A low perveance electron gun has been modelled/ designed for helix traveling wave tube (TWT) for long life application with an additional accelerating anode in the electron gun geometry. This pierce type convergent electron gun consists of M-Type dispenser cathode, electrically isolated beam focusing electrode and three isolated anodes has been designed using commercial software EGUN and CST-PS following Vaughan synthesis approach. For confined flow of the electron beam along the interaction structure (helix) of the TWT, periodic permanent magnet (PPM) focusing system has also been suitable modelled.
