暗物质粒子探测器（DAMPE）是一个用于高能宇宙射线和γ射线的卫星探测器。为了充分理解探测器的性能并获得可靠的物理结果，需要对探测器进行大量的模拟。这些模拟对于宇宙线核的数据分析特别重要，因为宇宙线核密切依赖于探测器材料中粒子的强子和核相互作用。广泛采用的仿真软件包括GEANT4和FLUKA，这两个软件都已在DAMPE仿真工具中实现。本文介绍了模拟工具DAMPE，并比较了两种模拟软件对量热计中质子簇射性质的模拟结果。这样的比较给出了我们的质子光谱分析的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.
