	Korea Atomic Energy Research Institute (KAERI) has used thermionic cathode-based microtron accelerator for operating compact THz FEL due to its compact size and high energy resolution. In this thermionic cathode-based microtron, rightly phased electron bunch train are automatically accelerated during the RF macro-pulse over threshold power for their emission. But, the thermionic cathode should be replaced with a photocathode for applying the microtron to UED or THz/X-ray pump prove experiment requiring femto-second and high peak current. But, it is needed to analyze precisely the electron beam dynamics in a microtron, especially, the relation between the RF phase in a microtron cavity and Laser input time for adapting the photocathode to a microtron. Hence, we conduct computer simulation with 3D PIC-code to find those optimized conditions for operating photocathode-based microtron.
