“…Due to these features, it has been widely used for various applications. For example, PHITS was extensively used in the design of the shielding, target, and neutron beam lines for the J-PARC project [12][13][14][15][16]. Both the beam transport functions for simulating particle trajectories in magnet fields, gravity, T0-choppers, and neutron super mirrors and the DPA calculation function are very useful in the design phase.…”

An upgraded version of the Particle and Heavy Ion Transport code System, PHITS2.52, was developed and released to the public. The new version has been greatly improved from the previously released version, PHITS2.24, in terms of not only the code itself but also the contents of its package, such as the attached data libraries. In the new version, a higher accuracy of simulation was achieved by implementing several latest nuclear reaction models. The reliability of the simulation was improved by modifying both the algorithms for the electron-, positron-, and photon-transport simulations and the procedure for calculating the statistical uncertainties of the tally results. Estimation of the time evolution of radioactivity became feasible by incorporating the activation calculation program DCHAIN-SP into the new package. The efficiency of the simulation was also improved as a result of the implementation of shared-memory parallelization and the optimization of several time-consuming algorithms. Furthermore, a number of new user-support tools and functions that help users to intuitively and effectively perform PHITS simulations were developed and incorporated. Due to these improvements, PHITS is now a more powerful tool for particle transport simulation applicable to various research and development fields, such as nuclear technology, accelerator design, medical physics, and cosmic-ray research.

“…It can be seen in this figure that the neutron trajectories are slightly deflected downward, i.e., they are directed to the ground due to the influence of gravity. The consideration of this slight deflection is of great importance in the beam line design of cold neutrons in the J-PARC project (Ebisawa et al, 2009;Mishima et al, 2009). …”
