High gain free electron laser at ETA
Abstract
A single pass, tapered electron wiggler and associated beam transport was constructed. The system is designed to transport 1 kA of 4.5 MeV electrons ith an emittance of 30 millirad cm. The planar wiggler is provided by a pulsed electromagnet. The interaction region is an oversized rectangular waveguide. Quadrupole fields stabilize the beam in the plane parallel to the wiggler field. The 3 meter long wiggler has a 9.8 cm period. The Free Electron Laser (FEL) serves as an amplifier for input frequencies of 35 GHz and 140 GZz. The facility is designed to produce better than 500 Megawatts peak power.
