Characterization and mitigation of coherent-optical-transition-radiation signals from a compressed electron beam
The Advanced Photon Source (APS) injector complex includes an option for rf photocathode (PC) gun beam injection into the 450-MeV S-band linac.At the 150-MeV point, a four-dipole chicane was used to compress the micropulse bunch length from a few ps to sub-0.5 virginia mill works tobacco road acacia ps (FWHM).Noticeable enhancements of the optical
