Recent Developments of the PHITS code

Abstract

PHITS, a general-purpose Particle and Heavy Ion Transport code System, has been used for various research fields such as radiation science, accelerator and its shielding design, space research, medical application, material research, and so on. Further developments of the PHITS code by improving the reaction models, including new physical processes and providing better user interfaces, are actively performed by the collaboration between RIST, JAEA, KEK, and Chalmers University. Recent developments of the PHITS code are presented concerned with the functions for “neutron long beam line”, high energy extension of the JQMD model, and event generator mode for low energy neutron transport.
