title: Design and Fabrication of an X-Band traveling wave deflection mode cavity for longitudinal characterization of ultra-short electron beam pulses

format: conference procceeding

conference: EPAC 2008

year: 2008

9 authors: A. Murokh | R. Agustsson | S. Boucher | P. Frigola | J.B. Rosenzweig | J. England | G. Travish | D. Alesini | V. Yakimenko

abstract: 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.

title: Study of X-ray Harmonics of the Polarized Inverse Compton Scattering Experiment at UCLA

format: journal article

year: 2004

8 authors: A. Doyuran | J. England | C. Joshi | P. Musumeci | J. B. Rosenzweig | S. Tochitsky | G. Travish | O. Williams

abstract: We propose an Inverse Compton Scattering (ICS) experiment, which will investigate nonlinear properties of the scattering utilizing the terawatt CO2 laser system with various polarizations in Neptune Laboratory at UCLA. When the normalized amplitude of the vector potential a0 is larger than unity the scattering occurs in the nonlinear region; therefore, higher harmonics are also produced. We present a calculation tool for the Double Differential Spectrum (DDS) distribution and total number of photons produced for both head-on and 90° scattering. We decided to do the experiment at 90° to avoid complications due to strong diffraction of the incoming laser. We discuss the electron and laser beam parameters for the experiment. ©2004 American Institute of Physics
