Figure 5
(a) Relative coincidence events (percentage) of the central pixel 5 of the 2 mm-thick REDLEN detector, for the array 3 and array 0, with the eight adjacent pixels at different CTWs and energies (109Cd, 241Am). The absolute percentage values of the coincidence events (within a CTW of 450 ns) are also shown (energy threshold of 3 keV). (b) The raw 241Am spectrum of the central pixel (black line), the spectrum of the coincidence events with all eight adjacent pixels (red line) and after charge-sharing discrimination (CSD) (blue line). |
