An FEL injector is under development based on the photoemission gun and superconducting radio frequency (srf) technologies established at CEBAF. The injector will deliver 10 MeV CW electron beams having a transverse normalized rms emittance < 11 p mm mrad and a longitudinal rms emittance < 35 p deg-keV with up to 200 pC charge within 8 ps (4s) at a repetition rate of 24.95 MHz or 2.495 MHz. Its performance has been modeled using a version of PARMELA with a point-by-point space charge algorithm. The details of modeling and the simulated performance of the injector are presented.
