论文摘要
暗物质粒子资源管理器（Dampe）是用于高能宇宙射线和$γ$ rays的卫星培养基检测器。为了充分了解检测器性能并获得可靠的物理结果，需要对检测器进行广泛的模拟。这些模拟对于宇宙射线核的数据分析尤为重要，该分析密切依赖于检测器材料中颗粒的辐射和核相互作用。广泛采用的仿真软件包括Geant4和Fluka，它们均已用于Dampe模拟工具。在这里，我们描述了Dampe的仿真工具，并比较了两个模拟软件中量热仪中质子淋浴性能的结果。这种比较给出了我们质子光谱分析中最重要的不确定性的估计。
The DArk Matter Particle Explorer (DAMPE) is a satellite-borne detector for high-energy cosmic rays and $γ$-rays. To fully understand the detector performance and obtain reliable physical results, extensive simulations of the detector are necessary. The simulations are particularly important for the data analysis of cosmic ray nuclei, which relies closely on the hadronic and nuclear interactions of particles in the detector material. Widely adopted simulation softwares include the GEANT4 and FLUKA, both of which have been implemented for the DAMPE simulation tool. Here we describe the simulation tool of DAMPE and compare the results of proton shower properties in the calorimeter from the two simulation softwares. Such a comparison gives an estimate of the most significant uncertainties of our proton spectral analysis.
