摘要
Plastic Scintillator Detector (PSD) of DArk Matter Particle Explorer (DAMPE) is designed to measure the charge of cosmic-rays and it servers as a veto for gamma-rays. In this work, we present some updated correction methods to further improve the quality of PSD charge measurement, especially for heavy nuclei. DAMPE has collected nearly 10 billions events by middle of 2021, it has substantial potential to measure the spectra of cosmic ray nuclei up to hundreds of TeV energies. These measurements could largely benefit from the correction of the PSD signal.
