Abstract :
Preliminary results are reported on experimental wakefield measurements made on a 6 cell, 17.14 GHz metallic photonic band gap (PBG) accelerator structure. Wakefields were observed using a variety of detectors and methods. The PBG structure is open, containing no outer wall, and radiation has been observed through a window in the surrounding vacuum vessel. The output coupler port has also been used with a vacuum window to observe radiation coupling out of the port. Estimations of radiation are made using HFSS and basic wakefield theory. Measurements have been made using video diode detectors and a heterodyne receiver. Plans are discussed for further experiments.
