我们使用粒子与重离子输运代码系统（PHITS）的最新版本（2.88版）在以下领域对58个案例（本文报道了22个案例，另有36个案例作为本文的在线补充材料报道）进行了基准研究：（1）20MeV到1GeV的核反应的粒子产生截面，（2）厚靶中子产额和中子屏蔽，（3）使用碳 - 12束在水中的深度 - 剂量分布，以及（4）从keV到GeV的宽能区的电子和光子输运。总体一致性被认为是足够令人满意的；然而，也观察到了一些差异，特别是在能量低于100MeV的粒子产生、锂 - 7（p，n）铍 - 7的中子产生以及光核反应方面。为了克服这些不准确之处并进一步改进代码，有必要在PHITS软件包中纳入高能版的评估核数据库JENDL - 4.0/HE以及光核数据文件JENDL - PD。
We performed a benchmark study for 58 cases (22 cases reported in this paper and 36 cases reported in online as supplementary materials of this paper) using the recent version (version 2.88) of the Particle and Heavy-Ion Transport code System (PHITS) in the following fields: (1) particle production cross-sections for nuclear reactions from 20 MeV to 1 GeV, (2) thick-target neutron yields and neutron shielding, (3) depth-dose distribution in water using C-12 beam, and (4) electron and photon transportation over a wide-energy range from keV to GeV. Overall agreements were found to be sufficiently satisfactory; however, several discrepancies are observed, particularly in particle productions with energies below 100MeV, neutron production for Li-7(p,n)Be-7, and photonuclear reactions. To overcome these inaccuracies and to further improve the code, it will be necessary to incorporate a high-energy version of the evaluated nuclear data library JENDL-4.0/HE and the photonuclear data file JENDL-PD in the PHITS package.
