Abstract :
The damping of wakefields is a critical issue in high gradient accelerators operating at high frequency. It is also very important in the next generation of accelerator structures. Photonic band gap (PBG) structures have uniquely motivated damping properties, and offer significant wake- field damping. The goal of this work is to quantify the higher order mode content of a constructed metallic PBG accelerator structure, and to provide direction for future structure design. Simulations are supported by experiments currently being performed to directly measure wakefields in a 6 cell PBG structure. Future design work will focus on a structure to be cold tested, tuned, and processed to high gradient operation at the MIT Haimson 17 GHz high gradient acceleration lab.
