粒子和重离子输运代码系统的升级版本PHITS2.52已开发并发布给公众。新版本与之前发布的PHITS2.24版本相比，不仅在代码本身，而且在包的内容（如附加的数据库）方面都有了很大的改进。在新版本中，通过实施几个最新的核反应模型，实现了更高的模拟精度。通过修改电子、正电子和光子输运模拟的算法和计算结果统计不确定度的方法，提高了模拟的可靠性。通过将活化计算程序DCHAIN-SP合并到新的包中，可以估计放射性的时间演变。由于实现了共享内存并行化，并对几个耗时算法进行了优化，提高了仿真效率。此外，还开发和整合了许多新的用户支持工具和功能，帮助用户直观有效地执行PHITS模拟。由于这些改进，PHITS现在是一个更强大的粒子输运模拟工具，适用于各种研究和开发领域，如核技术、加速器设计、医学物理学和宇宙射线研究。
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.
