title: Performance evaluation and optimization for a newly developed digital list-mode data acquisition Compton suppression spectrometer.
abstract: 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 (60)Co and (137)Cs 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.
