Abstract: The bismuth germanium oxide (BGO) electromagnetic calorimeter, which is characterized by a large detection energy range of 5 GeV–10 TeV for high-energy cosmic-ray electrons/positrons (CREs) and γ -rays, is the key sub-detector of the Dark Matter Particle Explorer (DAMPE). A careful and comprehensive calibration is essential for conducting accurate detector energy measurement. In this study, we present a method based on the ATmospheric Muon Neutrino Calculation 3-dimensional version (ATMNC3) software package, which achieves a stable and homogeneous inter-calibration in orbit for the DAMPE calorimeter.
