Figure 11
The raw spectra of central pixel 5 (black line), and the spectra of the coincidence events with all adjacent pixels (red line) and after CSD (blue line). The spectra were measured for the central pixel of both arrays: (a) and (b) array 3, and (c) and (d) array 1. The strong reduction of the shared events after CSD is clearly visible. Concerning the energy resolution, no improvements were obtained after CSD. The energy resolution values of central pixel 5 are: (i) for array 3, 9.5 and 3.6% at 22.1 and 59.5 keV, respectively; (ii) for array 1, 11.3 and 5.2% at 22.1 and 59.5 keV, respectively. |
