A TUNABLE ENERGY CHIRP CORRECTION

Le résumé fourni par la source

Short (subpicosecond) pulses are central to many of the next generation light source initiatives that are based on linear accelerators. Beam compression is performed by means of a chicane utilizing a correlated linear energy chirp. A small energy chirp is kept as the beam goes through the remaining accelerating stage to compensate for wakefield effects. It is necessary to compensate the residual energy spread before the beam enters the undulator stage. We present here a concept for a passive wakefield device chirp corrector or dechirper, to perform this compensation. We have recently demonstrated a passive energy chirp correction by selfwakefield at the Brookhaven ATF facility. In this paper we present a progress report on development of these tunable chirp correction devices.
