Abstract

The DArk Matter Particle Explorer (DAMPE) is a space-based particle detector launched on December 17th, 2015 from the Jiuquan Satellite Launch Center (China). The main goals of the DAMPE mission are the study of galactic cosmic rays (CR), the electron-positron energy spectrum, gamma-ray astronomy, and indirect dark matter search. Among its sub-detectors, the deep calorimeter makes DAMPE able to measure electrons and gamma-ray spectra up to 10 TeV, and CR nuclei spectra up to hundreds of TeV, with unprecedented energy resolution. This high-energy region is important in order to search for electron-positron sources, for dark matter signatures in space, and to clarify CR acceleration and propagation mechanisms inside our galaxy. A general overview of the DAMPE experiment will be presented in this work, along with its main results and ongoing activities.
