摘要：

With the development of high-intensity accelerators, it is now envisaged to build compact high-intensity neutron sources for various applications. At the CEA Saclay, we have started a project to promote such technology based on the existing 100 mA IPHI proton injector. We are focusing our interest on low-energy proton-induced reactions (less than 20 MeV) to provide an economical way to produce neutrons and also to limit the radiological constraints. Optimization studies of the target-moderator assembly require validated simulation tools in order to maximize the neutron flux. In this document, the development status of the GEANT4-based simulation tool is presented, as well as its validation by comparison with gold foil activation measurements on the IPHI proton injector. The experimental setup and the simulation procedure are described. A good agreement is obtained between experimental data and simulation results when considering angular distribution of primary neutrons provided by Howard and Yanch's measurements.
