摘要:
The advanced free-electron laser (AFEL) currently under construction at Los Alamos National Laboratory is a compact high-performance free-electron laser (FEL). The design of the AFEL integrates our most advanced accelerator and wiggler components. The 1.2 m long accelerator is designed to produce a high-brightness electron beam (e-beam) of 200 to 300 A peak current with an energy of 20 MeV. The beamline incorporates variable permanent-magnet quadrupoles and dipoles for electron beam transport. The AFEL will ultimately use 10 to 20 cm long slotted-tube pulsed microwigglers having a period of 3 mm to 1 cm. In this paper we present the design of the e-beam transport line and discuss the various design considerations.
