Analysis of Nuclear Cross Section Measurements for Particle Therapy — •Ronja Hetzel, Dominik Dorsel, Max Emde, Sebastian Lauber, and Achim Stahl — III. Physikalisches Institut B, RWTH Aachen University, Aachen, Deutschland

During ion therapy, nuclear reactions occur inside a patient. Substantial uncertainties are associated with the cross sections of these reactions.

Our working group develops an experiment to measure the cross sections of nuclear reactions in the collisions of protons and carbon ions. To identify the fragments, their kinetic energy, their time of flight, and their specific energy loss is measured with scintillation detectors. Measurements are performed at the medical accelerator at HIT in a fixed target experiment. The set-up is modelled in Geant4.

This contribution focuses on the analysis of measured data and simulation results to reconstruct the different particle types produced in the nuclear reactions.
