	During the month of October 2012 the commissioning of the light source FEL-2 at FERMI was successfully concluded. Fermi FEL-2 is the first seeded FEL operating with a double stage cascade in the "fresh bunch injection" mode. The two stages are two high gain harmonic generation FELs where the first stage is seeded by the 3rd harmonic of a Ti:Sa laser system, which is up converted to the 4th-6th harmonic. The output of the first stage is then used to seed the second stage. A final wavelengths of 10.8 nm was obtained as the 24th harmonic of the seed wavelength at the end of the two frequency conversion processes, demonstrating that the FEL is capable of producing single mode narrow bandwidth pulses with an energy of several tens of microjoules.

	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.
