Abstract
A project using the CEBAF superconducting rf linac to drive both IR and UV FELS is being considered. Although the linac, primarily designed for nuclear physics, need not be modified, a high intensity beam source must be added. The source will provide up to 60 A peak and 0.9 mA average current within a 15 mm mrad normalized emittance. Such currents, together with the small energy spread expected from CEBAF, yield a high optical gain and 1 kW of average optical power from each FEL. A bunching scheme from the source to the injector exit is presented with PARMELA calculations of the space charge dominated dynamics.
