论文摘要
提出了一种在大气中的新模型（$^3 $ h）的新模型。该模型属于CRAC（宇宙射线大气层级联）家族，被称为CRAC：3H。它基于使用Geant4工具包对宇宙射线引起的大气级联的完整蒙特卡洛模拟。 CRAC：3H模型首次能够在任何位置和时间计算trium的生产，对于主要入射宇宙射线颗粒的任何给定能量光谱，也是第一次明确处理的颗粒比质子重。该模型为使用$^3 $ H作为大气和水文循环的示踪剂提供了有用的工具。附加了用于实际使用该模型的数值配方。
A new model of cosmogenic tritium ($^3$H) production in the atmosphere is presented. The model belongs to the CRAC (Cosmic-Ray Atmospheric Cascade) family and is named as CRAC:3H. It is based on a full Monte-Carlo simulation of the cosmic-ray induced atmospheric cascade using the Geant4 toolkit. The CRAC:3H model is able, for the first time, to compute tritium production at any location and time, for any given energy spectrum of the primary incident cosmic ray particles, explicitly treating, also for the first time, particles heavier than protons. This model provides a useful tool for the use of $^3$H as a tracer of atmospheric and hydrological circulation. A numerical recipe for practical use of the model is appended.
