“…The physics list EPOS-LHC [21] is used for the energy interval 100 TeV -1 PeV for protons and 500 TeV -1 PeV for helium, by linking them to GEANT4 with the Cosmic Ray Monte Carlo (CRMC) package † [22]. Before launching DAMPE into space, several beam tests were performed at CERN, using ion beams of 40 GeV/n, 75 GeV/n and 400 GeV/n [23][24][25]. The data taken in the beam tests were compared with the simulations, showing a good agreement.…”

Recent observations of the light component of the cosmic-ray spectrum have revealed unexpected features that motivate further and more precise measurements up to the highest energies. The Dark Matter Particle Explorer (DAMPE) is a satellite-based cosmic-ray experiment that is operational since December 2015, continuously collecting data on high-energy cosmic particles with very good statistics, energy resolution, and particle identification capabilities. In this work, the latest measurements of the energy spectrum of proton+helium in the energy range from 46 GeV to 316 TeV are presented. Among the most distinctive features of the spectrum, a spectral hardening at ∼600 GeV has been observed, along with a softening at ∼29 TeV measured with a 6.6σ significance. Moreover, by measuring the energy spectrum up to 316 TeV, a strong link is established between space-and ground-based experiments, also suggesting the presence of a second hardening at ∼150 TeV. * https://geant4.web.cern.ch/node/302 † https://web.ikp.kit.edu/rulrich/crmc.html

“…After the ATMNC3 simulation, for the validation of our simulation results by comparing to flight data, all the primary and secondary particles generated are imported into the DAMPE official Geant4 simulation and reconstruction package (Jiang et al 2020), where the relativistic inelastic and elastic interaction between a particle and the DAMPE detector is simulated. In the end, the MC data are reconstructed using the same algorithm for the flight data reconstruction, and a Fig.…”

The Dark Matter Particle Explorer (DAMPE) has been undergoing a stable on-orbit operation for more than 6 years and acquired observation of over 11 billion events. And a better understanding of the overall radiation environment on the DAMPE orbit is crucial for both simulation data production and flight data analysis. In this work, we study the radiation environment at the low Earth orbit and develop a simulation software package using the framework of ATMNC3, in which state-of-the-art full 3D models of the Earth's atmospheric and magnetic-field configurations is integrated. We consider in our Monte Carlo procedure event-by-event propagation of the cosmic rays in the geomagnetic field and their interaction with the Earth's atmosphere, focusing on the particles above GeV that are able to trigger the DAMPE data acquisition system. We compare the simulation results with the cosmic-ray electrons and positrons (CREs) flux measurements made by DAMPE.The overall agreement on both the spectral and angular distribution of the CREs flux demonstrates that our simulation is well established. Our software package could be of more general usage for the simulation of the radiation environment at the low Earth orbit of various altitudes.
