La fragmentation du 12C à 95 MeV par nucléon appliquée au domaine de la hadronthérapie. Etude expérimentale et simulations sur cibles épaisses de PMMA.

Abstract : A study of the 12C fragmentation at 95 MeV per nucleon on thick PMMA targets is presented on this document. This study is motivated by the development of a new technique for irradiation of malignant tumours: the carbon ion therapy. The purpose of this work is to compare experimental data against nuclear models used in GEANT4 toolkit. The aim is to determine if the models are sufficiently predictive to the criteria of hadrontherapy. To achieve this goal, a first experiment was performed at GANIL with a 12C beam at 95 MeV/u and thick PMMA targets. This experiment has achieved the production rates, angular and energy distributions of different fragments produced in nuclear collisions. Comparisons between experimental data and simulated results obtained using the binary intra-nuclear cascade (BIC) and quantum molecular dynamics model (QMD) available in GEANT4 have been performed. These comparisons show the inability of the tested models to reproduce carbon fragmentation at 95 MeV per nucleon with the accuracy required in hadrontherapy.
