Abstract

Abstract

By introducing photonic crystal (or PBG) structure to the traditional disk-loaded accelerating tube, wakefields in the accelerating structure can be effectively damped. Machining methods of a 2D metallic PBG cavity were investigated and X-band PBG cavities with high quality factor were successfully fabricated. Suppression brought by the absorbers placed at the periphery of these PBG accelerating cavities is significant to the high order modes, but has very little effect on the accelerating mode TM01-like. Design and fabrication of a 4-cell traveling wave accelerating structure operating at the frequency of 11.42 GHz were accomplished and the cold test results were in agreement with the numerical simulations.
