A new approach for simulating D-T fusion interaction using the Geant4 toolkit

Abstract

Abstract In this study, the Geant4 toolkit is utilized to present a new approach for simulation of the D-T interaction. The neutron production cross-section and the energy/angle distribution of neutrons produced as the D-T data libraries are incorporated in the Geant4, and their performance is evaluated. The spectra shape of the produced neutrons of the D-T interaction simulated by the Geant4 show good agreement compared to the results of the comparative codes (i.e. MCUNED, ENEA-JSI, and DDT). However, some differences are observed, especially, in angular range of 90–95 degrees. The reason for these differences as well as the results of the proposed approach in comparison with the results of the benchmark experiments as the next study are under consideration.
