WebThe LCLS bunch compressor is an example of the multi-stage compressor with post-compression “dechirping” using wake fields in the NCRF linac. The bunches are shortened from 2 ps at the gun to ~40 fs at the undulator (50X compression). Example: LCLS Bunch Compressor 180 pC 30 A ge x 0.35 mm ge y 0.37 mm 220 MeV Dt 0.77 ps 0.05 % WebThe nominal LCLS accelerator design [1] provides a very narrow electron energy spread at 14 GeV of <0.03 % rms. This is achieved by using the strong longitudinal geometric wakefields of the micro-bunch in the linac S-band accelerating structures to cancel the linearly correlated energy spread of the second bunch compressor chicanes (BC2).
