Figure 17
The measured 57Co spectrum (ICR = 550 kcounts s−1) of the CZT A detector, using the fast PSHA (dead-time = 270 ns) and PSD. Energy resolution values of 7.7% FWHM at 122.1 keV (throughput of 53%) were measured. The reduction of pile-up effects, due to the PSD, is clearly visible. The counts are normalized to the total number of analyzed events in the spectra. |
