Abstract :
We report the design and cold test results for an 11 GHz photonic band gap (PBG) cell, which can be utilized as an accelerator cavity with reduced long-range wakefields. The eigenmodes of the two-dimensional (2D) PBG cavities formed by the defect in a triangular array of metal rods were studied numerically. A 2D PBG cavity with reduced HOM content was designed and built. Cold test results proved the suppression of the higher order modes (HOM) in the PBG cavity. A 6-cell 17.137 GHz PBG accelerator structure is proposed and designed.
