A comparative study was carried out between an analog timing and a digital list-mode data acquisition system for a Compton suppression spectrometer. The performance of both Compton suppression systems has been evaluated using the conventional, coincidence and anticoincidence spectra measured by 60Co and 137Cs point sources. The present study focuses on improving and optimizing the energy peak resolution and peak-to-Compton background ratios of the digital list-mode system.
► A digital list-mode data acquisition Compton suppression spectrometer was developed. ► The study is conducted to assess the performance of newly-developed spectrometer. ► The digital and analog counting systems are compatible in peak-to-Compton ratio. ► The full-energy peak losses can be recovered in the reconstructed anticoincidence spectrum.
