Abstract
This thesis investigates charge-changing and spallation cross sections in interactions between high-energy ion beams and high-density polyethylene targets, focusing on applications in space radiation shielding and carbon ion radiotherapy. Experimental measurements were performed using 290 and 400 MeV/nucleon 12C beams and 350 and 810 MeV/nucleon 16O beams. Key objectives include quantifying progeny fragment yields, analyzing target thickness effects, and improving Monte Carlo particle transport models, particularly the Particle and Heavy Ion Transport Code System (PHITS). Results highlight disparities between experimental data and Monte Carlo particle transport model predictions, particularly in spallation cross sections, underscoring the need for refined modeling. These findings contribute to better-informed strategies for radiation shielding and treatment planning in carbon ion radiotherapy
