Abstract

Electron bunch compression is critical to achieving the high peak currents required for efficient short wavelength FEL operation, but its success may depend sensitively on a number of parameters. From energy spectra of uncompressed bunches, we can characterize the longitudinal phase space (including bunch length, energy spread and energy chirp) of these bunches as a function of the injector parameters. These data serve as initial conditions in our simulations, which are then compared to our measurements of compressed bunches made using the chicane bunch compressor in the SDL at the NSLS (BNL).
