论文摘要
暗物质粒子资源管理器（DAMPE）被设计为用于探测宇宙射线的高能量粒子检测器，在较宽的能量范围内探测$γ-$射线。入射粒子的轨迹主要是由硅 - 丁香跟踪器 - 连接器（STK）子检测器测量的，这在很大程度上取决于精确的内部对齐校正以及全球坐标系的准确性。在这项工作中，我们进行了一种全球对齐方法，以验证这些子检测器的潜在位移，尤其证明，STK的轨道重建可以通过比较飞行数据和仿真来很好地满足所需的目标。
The Dark Matter Particle Explorer (DAMPE) is designed as a high energy particle detector for probing cosmic-rays and $γ-$rays in a wide energy range. The trajectory of the incident particle is mainly measured by the Silicon-Tungsten tracKer-converter (STK) sub-detector, which heavily depends on the precise internal alignment correction as well as the accuracy of the global coordinate system. In this work, we carried out a global alignment method to validate the potential displacement of these sub-detectors, and particularly demonstrated that the track reconstruction of STK can well satisfy the required objectives by means of comparing flight data and simulations.
