TL;DR: An upgraded version of the Particle and Heavy Ion Transport code system (PHITS2.52) was developed and released to the public in this article, which is a more powerful tool for particle transport simulation applicable to various research and development fields.

TL;DR: In this paper, the authors present a summary of the recent development of the multi-purpose Monte Carlo Particle and Heavy Ion Transport code system, PHITS, and discuss in detail the development of two new models, JAM and JQMD, for high energy particle interactions, incorporated in PHITS.

TL;DR: A Particle and Heavy Ion Transport code system (PHITS) was developed under the collaboration of JAEA (Japan Atomic Energy Agency), RIST (Research Organization for Information Science and Technology) and KEK (High Energy Accelerator Research Organization) as discussed by the authors.

TL;DR: In this article, the intensity and energy spectra of a quasi-monoenergetic 7 Li(p,n) neutron source at TIARA of Japan Atomic Energy Research Institute (JAERI) have been measured for eight incident proton energies between 43 and 87 MeV, using a proton recoil telescope (PRT) of annular geometry and a time-of-flight (TOF) method employing organic scintillators (BC501A, NE213).

TL;DR: A project team headed by University of Tsukuba launched the development of a new accelerator based BNCT facility by adopting Radio-Frequency Quadrupole+Drift Tube Linac type linac as proton accelerators and developing a new multi-modal Monte-Carlo treatment planning system based on JCDS.
