The Plastic Scintillator Detector (PSD) on top of DAMPE can be used to identify the species of cosmic ray particles by measuring their charge. In this paper, the procedure of charge measurement by PSD is described, including alignment of PSD, light attenuation correction, quenching and equalization correction. After these corrections we can get high precision charge spectrum, from which almost all the elements in cosmic rays from H to Ni can be clearly identified.

Abstract
The Plastic Scintillator Detector (PSD) on top of DAMPE can be used to identify the species of cosmic ray particles by measuring their charge. In this paper, the procedure of charge measurement by PSD is described, including alignment of PSD, light attenuation correction, quenching and equalization correction. After these corrections we can get high precision charge spectrum, from which almost all the elements in cosmic rays from H to Ni can be clearly identified.File in questo prodotto:
