The bremsstrahlung photon facility where photon beam can be created via bremsstrahlung processes has been installed in many different accelerator in the world. TARLA (Turkish Accelerator and Radiation Laboratory at Ankara) will be first facility of TAC (Turkish Accelerator Center) project in Turkey. An optimal design of collimator is important for obtain a clean high energy photon beam in a bremsstrahlung facility. In this study the photon spectrum has been obtained depending on the entrance angle of the collimator. The energy deposition and dose distributions on the collimator by photon beam generated from 30 MeV energy electron beam have been calculated with FLUKA Monte Carlo simulation code.
