The design of a high brightness driver linac for single pass high gain FEL experiments is being studied at NSRRC. Simulation of beam dynamics starting from the cathode of the 2998 MHz photo-injector to linac exit are performed by LiTrack and Elegant. To obtain a “flat-flat” distribution of electron bunches, the reverse tracking technique has been used to optimize the longitudinal dynamics. Results of beam dynamics and reverse tracking will be presented in this report.
