Figure 5
Measured (a) 241Am and (b) 57Co spectra of the central pixel of the large array after CSD (black line). The raw spectra of the central pixel (red line) and the spectra of the coincidence events with all eight adjacent pixels (green line) are shown. Energy resolution (FWHM) did not improve after CSD (1.9 keV at 59.5 keV and 2.4 keV at 122.1 keV). |
