The charges sharing and reconstruction study of the DAMPE silicon tungsten tracker
Abstract
The DArk Matter Particle Explorer (DAMPE) is one of the four satellites within the Strategic Pioneer Research Program in Space Science of the Chinese Academy of Science (CAS). The Silicon-Tungsten Tracker (STK), which is composed of 768 singled-sided silicon microstrip detectors, is one of the four subdetectors in DAMPE, providing track reconstruction and charge identification for relativistic charged particles. The charges sharing effect of STK was studied by charges-injection, SPICE simulation, test beam data and on-orbit data analysis. Based on this charges sharing effect, the on-orbit STK charge spectrum was reconstructed and shown.
