TARLA is the first facility to carry out in the Project of Turkish Accelerator Centre, which has been planned to be established first in Turkey, is very significant in terms of being the first source of radiation ray in Turkey. In this study, photon beam dump, which is one of the most important equipment of the experiment station has been done by using GEANT4 code to simulate and 3 ds Max program to design. After the determination of photon beam dump with sizes, backscattered particle amount calculated in detector area. It can be purposed that the photon beam dump with rectengular geometry can be used at TARLA bremsstrahlung photon facility.
