(a) The raw spectrum of the central pixel 5 (black line), the spectrum of the coincidence events with the negative pulses of the eight adjacent pixels (red line) and after charge-sharing discrimination (CSD) (blue line) for the 2 mm-thick REDLEN detector. (b) The time width distribution (with time bin widths of 10 ns) of all positive pulses of the central pixel 5 (black line) and of the coincidence positive pulses (red line). An energy threshold of 7 keV was used. |
