Summary
The comparison of experimentally achieved energy deposition function and the results of simulations show that FLUKA overestimates the range of uranium ions by 5% for 500 MeV/u and 10% for 950 MeV/u uranium beam. The ranges calculated by MARS and SHIELD-A give discrepancies below 5%, depending on the energy of the incident ion, which coincides with the measured ranges within the accuracy of the measurement.
Comparing the experimental and simulated depth profiles of the activated isotopes one could see that in case of Na-22 the codes show similar behaviour of the activation, though the discrepancies in the number of activated particles per incident ion per unit of depth are still observed, which could be explained by differences in cross sections. For this case FLUKA shows better agreement with the experiment, than MARS and SHIELD-A. In case of Be-7 the results of simulations differ in behaviour with the experimentally achieved ones, which could be explained by physical models implied in the codes.
