Abstract :
The design for a potential free electron laser (FEL), driven by a 120-MeV linac capable of generating 0.1-A macropulse average current beams at a duty factor of 0.6%, is described. The accelerator will employ a photo-injected, 18-MeV, 433-MHz linac as an injector, followed by a 1300-MHz longitudinal phase space “linearizer”, a magnetic buncher, and seven sections of 1300-MHz, pulsed traveling wave linac structure. Pulse lengths of 7 ps will be attained with minimal distortion of the pulse profile and normalized 90% emittance of 30±10 π-mm-mr. The magnets used to transport the beam from the linac to the FEL centerline, the wiggler, and the optical resonator will be reclaimed from previous FEL demonstration experiments
