Fig. 1 The combined signal spectra of PSD for protons and helium nuclei.
The combined signal spectra of PSD for protons and helium nuclei. The left panel is for BGO deposited energies between 447 and 562 GeV, the middle panel is for BGO deposited energies of 4.47 to 5.62 TeV, and the right panel is for BGO deposited energies between 20 and 63 TeV. The on-orbit data (black) are shown, together with the best-fit templates of simulations of protons (blue), helium nuclei (green), and their sum (red). The vertical dashed lines show the cuts to select proton candidates in this deposited energy range. DAMPE Collaboration et al.
