Bremsstrahlung photons are created by electron beams de-accelerating in electric field (coupling with a thin radiator) and are used in a variety of different fields. In nuclear physics experiments it is important to transport and focus the created photon beam into the experimental cavity. Here angular distribution of the photon beam is one of the important parameters, which should be known. In this study a FLUKA simulation has been done to obtain angular distribution of photon beam created by interaction of 40 MeV electron beam with the tantalum (Ta) radiator of varied thickness, which is planned to be used in bremsstrahlung photon facility at TARLA (Turkish Accelerator and Radiation Laboratory in Ankara). TARLA will be the first facility of Turkish Accelerator Center project.
