PBPL Publications: 2008-00016 PUBLICATION DESIGN AND FABRICATION OF AN X-BAND TRAVELING WAVE DEFLECTION MODE CAVITY FOR LONGITUDINAL CHARACTERIZATION OF ULTRA-SHORT ELECTRON BEAM PULSES

An X-band Traveling wave Deflector mode cavity (XTD) has been developed at Radiabeam Technologies to perform longitudinal characterization of the subpicosecond ultra-relativistic electron beams. The device is optimized for the 100 MeV electron beam parameters at the Accelerator Test Facility (ATF) at Brookhaven National Laboratory, and is scalable to higher energies. An XTD is designed to operate at 11.424 GHz, and features short filling time, femtosecond resolution, and a small footprint. RF design, fabrication procedure, and commissioning plans are presented. An experimental program at ATF to utilize the deflector for compressed beam characterization is discussed, including proposed measurements of the phase space filamentation due to non-linear processes in a chicane compressor.
