Figure 9
(a) 2D scatter plot of the energy ECSA of the coincidence events (m = 2) between pixels 5 and 4 for a photon interaction at the centre of the inter-pixel gap. The energy ECSA is plotted versus the charge-sharing ratio R, which provides information about the interaction position of the events. The red line represents the best fitting function used to correct charge losses after CSA. (b) The raw spectrum of pixel 5 (black line), the energy spectrum after CSA (blue line) and the spectrum after the proposed correction technique (red line) with the fitting function of Fig. 9(a). The energy resolution after CSC is equal to 3.0 keV. |
