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