The given work is devoted to the description of a method for creating a target converter of bremsstrahlung when an electron beam passes through it on the example of a target made of tungsten with a thickness of 2 mm. The purpose of the work is to use computational and experimental methods to create a target converter of bremsstrahlung using software packages and experimental verification of the calculated results. To select the material and thickness of the target, it is necessary to know the characteristics of the bremsstrahlung and the electron beam incident on the target. In this work, the MCC 3D and GEANT4 programs using the Monte Carlo method for calculating the interaction of radiation with matter are considered. Expressions were obtained to estimate the yields of bremsstrahlung gamma quanta and primary electrons from the target, angular distributions of bremsstrahlung and electron radiation and the dependence of the average energy of gamma quanta and electrons on the departure angle were constructed. Measurements and calculation of the bremsstrahlung profile by the Monte Carlo method were carried out. The results of the work carried out can be applied in medicine, metrology of ionizing radiation and in works when it is necessary to evaluate the yield of bremsstrahlung or electronic radiation. The present work can be continued for more accurate calculations in a wider range of energies and materials.
