暗物质粒子探测器（DAMPE）是中国科学院空间科学战略先锋研究计划的四颗卫星之一。DAMPE可以探测到电子，光子在很宽的能量范围（5 GeV至10 TeV）和离子高达铁（100 GeV至100 TeV）。硅钨示踪器（STK）是DAMPE中的四个子探测器之一，提供光子-电子转换、径迹重建和离子电荷识别。用60 GeV/u铅原束在CERN进行了离子束实验。研究了STK探测器的电荷重构和电荷分辨。
The DArk Matter Particle Explorer (DAMPE) is one of the four satellites within Strategic Pioneer Research Program in Space Science of the Chinese Academy of Science (CAS). DAMPE can detect electrons, photons in a wide energy range (5 GeV to 10 TeV) and ions up to iron (100GeV to 100 TeV). The silicon-Tungsten Tracker (STK) is one of the four subdetectors in DAMPE, providing photon-electron conversion, track reconstruction and charge identification for ions. An ion beam test was carried out in CERN with 60GeV/u Lead primary beams. Charge reconstruction and charge resolution of STK detectors were investigated.
