(a) Measurements of ratio of collected charge for different energies in the 250 eV to 1 keV range (very high gain mode, CMA, operating mode suppressing cross-talk). The RCC is defined as the ratio between ‘photon peak’ separation (i.e. charge collected by a pixel) and the expected charge generation (under ideal conditions). (b) Single-photon discrimination capability: SNR at different energies in the 250 eV to 1 keV range (very high gain mode, CMA, operating mode suppressing cross-talk).
