摘要
DAMPE (DArk Matter Particle Explorer) is a satellite-born experiment promoted by the Chinese Academy of Sciences, with the collaboration of Italian and Swiss agencies. Since December 2015, DAMPE flies at the altitude of 500 km and collects data smoothly. The detector is made of four sub-detectors: top layers of plastic scintillators, a silicon-tungsten tracker, a BGO calorimeter (32 radiation lengths), and a bottom boron-doped scintillator to detect delayed neutrons. The main goal of the experiment is the search for indirect signals of Dark Matter in the electron and photon spectra with energies up to 10 TeV. Furthermore DAMPE studies cosmic charged and gamma radiation. Moreover, the calorimeter depth and the large acceptance allow to measure cosmic ray fluxes in the range from 20 GeV up to hundreds of TeV with unprecedented precision. An overview of the latest results about the charged cosmic rays will be presented.
