Particle and Heavy Ion Transport Code System: PHITS

Abstract

The multi-purpose Monte Carlo Particle and Heavy Ion Transport code System, PHITS, has been developed. Details of two important models, JAM and JQMD, incorporated in PHITS are discussed, and comparisons between model calculations and experiments are shown for the validations of these models. Three different application fields of PHITS; accelerator facilities, heavy ion therapy and space radiation are introduced. The results shown in this paper clearly indicate that PHITS has a great ability of carrying out the radiation transport analysis of almost all particles and heavy ions within a wide energy range.
