Double differential neutron yields from carbon target irradiated by 5 MeV and 9 MeV deuterons were measured at the Kyushu University Tandem Accelerator Laboratory. A carbon target was thick enough to stop the incident deuterons in the target. An NE213 liquid organic scintillator was employed to detect neutrons emitted from the target and placed at several directions from 0° to 140°. To estimate the contribution of scattered neutrons from the floor and walls, neutron yields were measured with an iron shadow bar located in front of the scintillator. The measured energy spectrum was derived by an unfolding method with FORIST and MAXED codes using the response functions of the NE213 scintillator calculated with the SCINFUL-QMD code. The incident energy dependence of total thick target neutron yields for carbon was investigated over the energy range from 5 to 50 MeV and the empirical formula was obtained. The measured neutron energy spectra were also compared with the calculations by PHITS code.

Extension of the Liège intranuclear-cascade model to reactions induced by light nuclei

The purpose of this paper is twofold. First, we present the extension of the Liège intranuclear-cascade model to reactions induced by light ions. We describe here the ideas upon which we built our treatment of nucleus-nucleus reactions and we compare the model predictions against a vast set of heterogeneous experimental data. In spite of the discussed limitations of the intranuclear-cascade scheme, we find that our model yields valid predictions for a number of observables and positions itself as one of the most attractive alternatives available to GEANT4 users for the simulation of light-ion-induced reactions. Second, we describe the C++ version of the code, which is physicswise equivalent to the legacy version, is available in GEANT4, and will serve as the basis for all future development of the model.

Abstract.Depth distributions of positron-emitting nuclei in PMMA phantoms are calculated within a Monte Carlo model for Heavy-Ion Therapy (MCHIT) based on the GEANT4 toolkit (version 8.0). The calculated total production rates of 11 C, 10 C and 15 O nuclei are compared with experimental data and with corresponding results of the FLUKA and POSGEN codes. The distributions of e + annihilation points are obtained by simulating radioactive decay of unstable nuclei and transporting positrons in surrounding medium. A finite spatial resolution of the Positron Emission Tomography (PET) is taken into account in a simplified way. Depth distributions of β + -activity as seen by a PET scanner are calculated and compared to available data for PMMA phantoms. The calculated β + -activity profiles are in good agreement with PET data for proton and 12 C beams at energies suitable for particle therapy. The MCHIT capability to predict the β + -activity and dose distributions in tissue-like materials of different chemical composition is demonstrated.
