Description
Summary:In nuclear medicine radionuclides are used in diagnosis and therapy. They can be produced in cyclotrons with different nuclear reactions. Overall goal is the optimization of the yield of the desired radionuclide which is possible by changing different experimental parameters. To test the influence of these parameters to obtain an optimal yield, simulation programs like PHITS and FLUKA can be used. In first studies (see Klink et al. [Testing the suitability of FLUKA and PHITS to predict the outcome of radionuclide production. Radiat. Eff. Defects Solids 2023, 178 (1-2), 111-125]) the experimental yields of nuclide productions were compared with simulation results of different target designs with perpendicular and inclined configuration. In this paper we focus on the effect of inclination since it was one of the problematic cases of the previous study [Klink et al. Testing the suitability of FLUKA and PHITS to predict the outcome of radionuclide production. Radiat. Eff. Defects Solids 2023, 178 (1-2), 111-125]. Different beam profiles were varied in the simulations to determine its influence on the simulated yields. The choice of the beam profile has a great influence on simulating irradiations of inclined targets. With a known beam profile and other experimental conditions, FLUKA can be used to simulate nuclide productions of inclined targets with small deviations compared to the experimental yields. In conclusion, FLUKA can be used to determine the yield of unknown nuclide production with different target designs.
