Overview of the PHITS code and application to nuclear data. Radiation damage calculation for materials

A general purpose Monte Carlo Particle and Heavy Ion Transport code System, PHITS, is being developed through the collaboration of several institutes in Japan and Europe. PHITS can deal with the transport of nearly all particles, including neutrons, protons, heavy ions, photons, and electrons, over wide energy ranges using various nuclear reaction models and data libraries. All components of PHITS such as its source, executable and data-library files are assembled in one package. More than 2,000 researchers have been registered as PHITS users, and they apply the code to various research and development fields such as nuclear technology, accelerator design, medical physics, and space science. This report briefly summarizes the physics models implemented in PHITS, and introduces the new event generator mode. We will also present the radiation damage data for materials such as the energy spectra for the Primary Knock-on Atoms (PKA) and the Kinetic Energy Released per unit MAss (KERMA) factors calculated by the new event generator mode under the IAEA-CRP activity titled 'Primary radiation damage cross section (2013-2017).'
