(a) Coincidence events (percentage) for central pixel 5 with other adjacent pixels at different CTWs and at both low (circles) and high (triangles) rate conditions. Due to the high rate condition, the blue curve does not saturate. (b) High rate coincidence spectra at different CTWs. This result clearly shows that the coincidence technique fails at high ICRs, due to the presence of false-shared events, i.e. coincidence events due to photons interacting simultaneously on neighbouring pixels. The energy distribution of the coincidence events highlights the presence of false shared events, even at a CTW of 10 ns.
