Dark Matter Particle Explorer: Ten-Year On-Orbit Performance and Scientific Outcomes

Abstract: The Dark Matter Particle Explorer (DAMPE, also known as ``Wukong'') is the first scientific space mission within the framework of the Strategic Pioneer Program on Space Science of the Chinese Academy of Sciences. The main scientific objectives of DAMPE include indirect detection of dark matter, cosmic-ray physics, and high energy gamma-ray astronomy. Thanks to its large geometrical factor and thick imaging calorimeter, DAMPE could effectively detect cosmic-ray electrons (including positrons) and gamma-rays up to 10~TeV, and nuclei up to PeV. Since launched on 17 December 2015 into a Sun-synchronous orbit, DAMPE has been smoothly operating on orbit for more than ten years. Here we present an overview of instrument, on-orbit status, and highlight scientific results of DAMPE, including the measurements of the all-electron energy spectrum and the spectra of protons and other nuclei, and high energy gamma-ray line search.
