Energy Recovery Transport Design for Peking University FEL.

摘要

A free-electron laser based on a superconducting linac is under construction in Peking University. To increase FEL output power, energy recovery is chosen as one of the most potential and popular ways. The design of a beam transport system for energy recovery is presented, which is suitable for the Peking University construction area. Especially, a chicane structure is chosen to change path length at -20 degree and M56 in the arc is adjusted for fully bunch compression.
