We report progress on the design and cold test of a metal Ku-band PBG accelerator structure. The 17.140 GHz 6-cell PBG accelerator structure with reduced long-range wakefields was designed for the experiment. The copper structure was electroformed and cold-tested. Tuning was performed through chemical etching of the rods. Final cold test measurements were found to be in very good agreement with the design. The structure will be installed on the beam line at the accelerator laboratory at Massachusetts Institute of Technology and will be powered with 3 MW of peak power from the Haimson 17.14 GHz klystron. Results of the design, fabrication, cold test and hot test on the Haimson accelerator will be presented.

A high-power mm-wave source architecture is being developed at Los Alamos, based on the interaction of a sheet-electron beam with a ridged waveguide slow-wave structure. This type of traveling-wave source is capable of producing peak output rf powers up to 500 kW at 100 GHz. We will describe the source concept, present interaction simulations, and review rf structure design and cold test results and sheet beam propagation experiments.
