Description
General-purpose radiation transport code PHITS has been improved in recent years. Following is the list of major updates.
1, The extension of the cross section data reading module. Previously, it was compatible with those of protons, neutrons and electron-gamma shower. The current version can read cross sections of alphas, deuterons, and photo-nuclear reactions.
2, The modernization of burn-up calculation code DCHAIN. Neutron activation cross section, decay data and photon dose conversion coefficient libraries were replaced with modern ones. The uncertainty in the transport phase is considered.
3, The functionality to calculate the response of the result to input parameters.
4, Interactive 3D geometry viewer PHIG-3D.
5, Cosmic ray source function.
6, Track-structure calculation models, which calculate atomic-scale reactions of charged particles on event-by-event basis, for electrons, positions, and heavy ions.
7, RT-PHITS, an interface dedicated to radiation therapy, which can handle DICOM data on treatment planning,PET-images, CT-images and phase space files.
8, Random number by Xorshift64
9, User-defined stopping power
10, Mu-pair production
In addition, PHITS has been recently benchmarked against the shielding experimental data of SINBAD. This benchmark illustrated that the use of high energy cross section data library JENDL-HE/4.0 is effective to reproduce the measured reaction rates and spectra. Calculation by the default settings using nuclear reactions models, INCL4.6 and GEM, overestimated the scattering in thick shielding and failed to consider secondary neutron spectral peaks.
