Abstract: High integration, simple followup operations, and flexible data processing are the main advantages of digital systems in comparison to traditional analog electronics modules. In this experiment, we try to use the PixieNet digital instrument in the anticoincidence measurement to replace complex traditional electronic acquisition systems and to simplify experimental setups and procedures. The experimental results demonstrate that using the PixieNet digital instrument yields superior anticoincidence effects compared to that using traditional electronic devices, which can be replaced by PixieNet digitizer.

Key words: PixieNet digitizer, AntiCoincidence measurement, ratio of PeaktoCompton
