Numerical evaluations have been performed to install a photo-cathode RF-gun into an oscillator FEL system which has been developed in Kyoto University. The original FEL system was consisted of a 4.5-cell thermionic RF gun with S-band accelerator tube of 3-m to oscillate the mid-infrared FEL. The electron beam properties have been evaluated from an RF-gun to an FEL by using PARMELA and ELEGANT. On the other hand, the FEL parameters have been calculated with GENESIS which takes the optical cavity into account. The evaluated peak current of the electron beam was 10-50 times as high as those with the thermionic RF-gun. Since the oscillator FEL requires a multi-bunch electron beam, evaluation of the round-trip development of the FEL has been also performed by a 100 bunch train beam. The results showed that the FEL gain saturation was achieved within 3 round-trips.
