We report the progress on the design and cold test of metallic photonic band gap (PBG) resonators and PBG accelerator structures. First, an 11 GHz PBG resonator, which can be utilized as an accelerator cavity with reduced long-range wakefields, was constructed and tested. The higher-order-modes suppression was proved in the cold test. A Q-factor of 5000 was achieved for a brazed resonator. Next, a 6-cell 17.137 GHz PBG accelerator structure with reduced long-range wakefields was designed. A high Q 6-cell 17.137 GHz PBG accelerator was electroformed and is currently cold tested. A PBG structure will be tested at high power and will be used to accelerate an electron beam at Massachusetts Institute of Technology.
