我们升级了粒子和重离子输运代码系统（PHITS）的许多功能，并发布了新版本PHITS3.02。由于对核反应模型进行了修正，并加入了新的原子相互作用模型，大大提高了程序的精度，扩大了程序的适用范围。压缩历史和轨道结构两种方法都被用于处理电子和正电子的传递，尽管后者仅在液态水的模拟中可靠。此外，还开发了一些用户支持功能，例如有效获得统计上更好结果的新计数、放射性同位素源生成功能以及可将PHITS应用于医学物理学的软件工具。由于代码的不断改进和推广，注册用户数量已超过3,000人，并被用于各种研究领域，包括加速器设计、辐射屏蔽和防护、医学物理学和宇宙射线研究。本文总结了PHITS3.02的基本特点，特别是物理模型和PHITS2.52在2013年发布后实现的功能。
We have upgraded many features of the Particle and Heavy Ion Transport code System (PHITS) and released the new version as PHITS3.02. The accuracy and the applicable energy ranges of the code were greatly improved and extended, respectively, owing to the revisions to the nuclear reaction models and the incorporation of new atomic interaction models. Both condense history and track-structure methods were implemented to handle the electron and positron transport, although the latter is reliable only for simulations in liquid water. In addition, several user-supportive functions were developed, such as new tallies to efficiently obtain statistically better results, radioisotope source-generation function, and software tools useful for applying PHITS to medical physics. Owing to the continuous improvement and promotion of the code, the number of registered users has exceeded 3,000, and it is being used in diverse areas of study, including accelerator design, radiation shielding and protection, medical physics, and cosmic-ray research. In this paper, we summarize the basic features of PHITS3.02, especially those of the physics models and the functions implemented after the release of PHITS2.52 in 2013.
