Abstract：
Thi spaper describes thedesign,simulation and experiment of a multi-cavity RF gun with thermionic cathode for BFEL.This RF gun consists of 1/2+3 cavities (its first half cavity is about 1/3 of a full cavity) with a axis coupling bi-period standing-wave accelerating structure,and works at π/2 mode,2856MHz.We shortened the length of the lst cavity and added a short drift between the 2nd and 3rd cavities,so that the power of back bombardment electrons was greatly decreased and the logitudinal properties were adjusted properly.
