Dark Matter Particle Explorer (DAMPE) is a satellite-borne detector devoted to measure the fluxes of high-energy cosmic rays (electrons and positrons, photons, protons and nuclei). The DAMPE covers energies up to 10 TeV for electrons and photons and up to 100 TeV for charged nuclei. DAMPE has been launched on December 17th, 2015, and it runs smoothly since then. The Plastic Scintillator Detector (PSD) is designed to accurately measure the charge of cosmic-ray particle and as a veto for Gamma-ray detection. By means of the PSD performance, DAMPE is capable of studying the elemental composition of charged cosmic rays up to Nickel (Z=28). In this contribution, the PSD performances and the status of cosmic-nuclei analysis, with preliminary results on carbon analysis, ultra-heavy nuclei and fractional charge particle searching with DAMPE are presented.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
