Description
The DArk Matter Particle Explorer (DAMPE), launched in December 2015, is a space-based calorimeter designed for high-energy cosmic ray detection (tens of GeV to hundreds of TeV), gamma-ray astronomy, and indirect dark matter searches, benefiting from its large acceptance and excellent charge/energy resolution. After more than ten years of smooth on-orbit operations, DAMPE has delivered precision measurements of galactic cosmic ray fluxes, including new spectral features in proton and helium spectra, secondary-to-primary ratios such as B/C, and ongoing analyses of light, intermediate, and heavy nuclei. Recent results reveal charge-dependent spectral softenings from proton to iron at ~15 TV rigidity. These measurements offer crucial insights into cosmic ray acceleration and propagation. The presentation will also highlight recent gamma-ray observations and constraints on dark matter annihilation/decay from the DAMPE mission.
