Abstract

The general-purpose radiation transport simulation code PHITS was validated against SINBAD, a comprehensive radiation shielding benchmark database. Unlike previous studies that primarily focused on proton accelerator shielding, this work extended the validation to a wider range of experimental data, including double-differential neutron yields, activation, remnant dose, and microdosimetric quantities induced by protons, electrons, ions, and pions. While PHITS predictions generally agreed with experimental data within a factor of two, indicating sufficient accuracy of transport and burn-up calculations, the comparison highlighted deficiencies in several nuclear reaction models. Specifically, the high-energy hadron cascade model for neutron production and isomer production, evaporation model, and heavy-ion reaction model can be refined further for higher accuracy.

利用SINBAD对各种弹丸和可观测物的PHITS进行基准研究

针对综合辐射屏蔽基准数据库SINBAD，对通用辐射输运模拟代码PHITS进行了验证。与先前主要关注质子加速器屏蔽的研究不同，这项工作将验证扩展到更广泛的实验数据，包括双差中子产量、激活、残余剂量和质子、电子、离子和介子诱导的微剂量。虽然PHITS的预测结果与实验数据大体一致，误差在两倍以内，表明输运和燃耗计算具有足够的准确性，但这一比较突出了几个核反应模型的不足之处。具体来说，高能强子级联产生中子和异构体模型、蒸发模型和重离子反应模型可以进一步细化，以提高精度。

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
