MODELING THE CHARACTERISTICS OF PHOTONS AND RESIDUAL ELECTRONS IN BREMSSTRAHLUNG BEAMS GENERATED BY A TANTALUM CONVERTER ON THE M-30 MICROTRON

The results of simulations are presented: the characteristics (energy spectra, their integral characteristics, transverse distributions in the plane) of the beam of electrons and secondary photons at the output of the electron accelerator, specifically, in the placement plane of the tantalum converter, and the characteristics of photons and residual electrons in the bremsstrahlung beams generated by the tantalum converters (thicknesses of 0.04, 0.4, 1.0, 4.0, and 10.0 mm) in the placement plane of irradiated samples. Calculations were performed for the electron accelerator IEP NAS of Ukraine - microtron M-30, considering its technical characteristics at a fixed initial electron energy of 17.5 MeV. The GEANT4 toolkit was used for the simulations. The information obtained was utilized to optimize the process of stimulating hotonuclear reactions on actinide nuclei and to predict the results.
