Measurement of cosmic ray proton spectrum with the Dark Matter Particle Explorer
2019 July 22
The precise measurement of the energy spectrum of cosmic ray proton is very important for the study of cosmic ray physics. The DArk Matter Particle Explorer (DAMPE), a space-based high energy particle detector, has a very good potential to measure cosmic-ray protons up to 100 TeV. Since its successful launch on December 17, 2015, DAMPE has been operated on-orbit for more than three years. Here, the analysis of the cosmic-ray proton spectrum from 40GeV to 100TeV with DAMPE experiment will be reported.
