Neutron energy spectra at 0 degree produced from stopping-length thick graphite, aluminum, iron and lead targets bombarded by 250 MeV and 350 MeV protons were measured at the neutron TOF course at RCNP of Osaka University. The neutron energy spectra were obtained by using the time-of-flight technique in the energy range from 10 MeV to incident proton energy. To compare the experimental results, Monte Carlo calculations by the PHITS and MCNPX codes using the JENDL-HE and the LA150 evaluated nuclear data files were performed. It was found that these calculated results at 0-degree generally underestimated the experimental results for all targets in the energy range above 20 MeV.

A particle and heavy ion transport code is an essential implement in the design study of accelerator facilities for various purposes such as radiotheraphy, spallation neutron source and rare isotopes production, and also in space technology. We have therefore developed a multi-purpose particle and heavy ion transport Monte Carlo code system, PHITS (Particle and Heavy Ion Transport code System), based on the NMTC/JAM code. PHITS has three important ingredients which enable us to simulate (1) hadron-nucleus reactions with energies up to 200 GeV, (2) nucleus-nucleus collisions from 10 MeV/nucleon up to 100 GeV/nucleon, (3) transports of heavy ions, all hadrons including low energy neutrons down to 10
eV, and leptons. In this paper, we report a brief description of the models incorporated in the PHITS code and the present status of the code, showing some benchmarking tests of the PHITS code for accelerator facilities.
