dE/dx − dE/dx method applied to simulation data of electrons, protons, helium ions, and muons similar to Panel a in Figure 5. A two-dimensional histogram of particles in ACD coincidence is shown, which means that the visualized particles deposited energy in SSD Stages A and C as well as Scintillator Stage D. Therefore, the particles also passed through Cherenkov Stage B. The abscissae show the energy loss in Scintillator Stage D while the ordinates show the energy loss in SSD Stage C. For SSD Stage C, the maximum value of the signals measured by the two readout segments of the SSD is taken, as a particle can only deposit energy in one readout segment while passing through SSD Stage C. Individual histograms were created separately for each simulated particle type and added afterwards to create the depicted combined histogram. Additionally, contour lines are shown to indicate where each particle type appears within the histogram. The contour lines are based on the histograms created for the individual simulated particle types and lie at the respective 5% levels of the maximum histogram values.
