Abstract

Abstract The applicability of the high quality, continuous electron beam from the CEBAF accelerator to free electron laser (FEL) research and photon production has been examined. A simple electromagnetic wiggler utilizing the output of the CEBAF injector (modified to include a new, continuous pulse train, high brightness photoemission gun) would produce output powers of ∼ 1 kW CW in the 45-20 μm wavelength range. With a similar 6 cm wavelength EM wiggler of twice the length with a 400 MeV beam from the North Linac comparable laser output could be achieved at wavelengths around 200 nm. Analysis to date includes conceptual design optimization and more detailed modeling of the optimized parameter space. Program plans as well as designs for the two FELs are presented.
