Abstract

Abstract

Stringent tolerance budget is restricted on the linear accelerator (linac) parameters, such as the mean beam energy stability, peak current variation, electron bunch arrival time jitter, and the transverse beam position offset, in order to generate stable output pulses in modern linac driven free electron laser facility. In this paper, a corrugated pipe is used as a beam energy stabilizer. Analytical and numerical methods for designing such kind of stabilizer are described, and the simulation results show that the beam energy jitter can be reduced more than 10% after this structure is adopted for the case of Dalian Coherent Light Source (DCLS) linac.
