Detection efficiency with single X-ray photon discrimination for GOS:Tb powder screens based on Geant4 simulation (10000 events per energy). To exclude out-of-pixel interactions due to fluorescence from the gadolinium as well as Compton scattering, the interaction region is limited to 50 µm × 50 µm. According to Section 3.3[link], the applied energy thresholds allow single X-ray photons to be detected with our detection scheme. The absorption efficiencies of silicon-based direct detectors (Berger et al., 2010BB5) are provided for comparison.
