Bremsstahlung has an important place in the field of experimental physics and photons-matter interaction especially in terms of materials characterization and analysis. Bremsstrahlung photon occurs by a high-energy electron deflected in the electric field of and atomic nucleus. Bremsstahlung is an important experimental study not only in the field of nuclear physics and particle physics but also in the field of solid state physics, applied physics, astrophtsics. In this study some calculations were performed for bremsstrahlung photon flux consisting of Tantalum (Ta) target for some different thickness.
