Outline of Final Research Achievements

Fragmentation cross-sections in the energy range from 10 to 1000 MeV/u of nuclei important for heavy ion therapy and manned space missions were measured. The cross-sections were measured in C(Pb,x), and C(C,x) reactions as functions of angle. In this study, the measured cross-sections were used to benchmark radiation transport simulation code PHITS to improve its reaction models. In particular, the quantum molecular dynamics model, which dominates the fragment production cross sections, was revised and implemented to PHITS.
