Energy recovery transport design for PKU FEL

A SRF linac based free electron laser user facility is under developed at Peking University. Energy recovery Linac technology was chosen for increase of average electron beam current, hence, increase of the free electron laser power. In this paper we present a conceptual design of beam transport line which satisfies requirement of ERL. A chicane consisting of four identical bend magnets is selected for path length adjustment up to ?? 18 degree. R56 of both arcs of the beam line is adjustable for full bunch compression. ?2007 IEEE.EI
