Abstract：
In this paper, the design, simulation, and experimentation of a multi-cavity RF gun with a thermionic cathode for BFEL is described. This RF gun consists of 1/2+3 cavities with an on-axis coupling structure operated in the π/2 mode at 2856 MHz. We shorten the first cavity and add a short drift section between the second and third accelerating cavities, so that the power of back bombardment is decreased significantly and the longitudinal properties are adjusted properly.
