Abstract:

Background: The detector probe is composed of double-end output plastic scintillation detector and silicon photomultiplier (SiPM), and it's part of the detector system with back end electronics system such as digitizer. Purpose: To study the optimization of the detection efficiency of real events and energy resolution with different data processing methods, the standard γ source 60Co and 137Cs are used to test the plastic scintillation detector system. Methods: The effect of the coincidence time of the associated event on detection efficiency is discussed, and the improvement of energy resolution from the integral length and the pulse shape discrimination(PSD) window is analyzed. Results: and Conclusion: The results show that the real event detection efficiency is the best when the coincidence time of the related event is 15 ns, and the energy resolution is optimized from 53.38% to 42.21% under the PSD window when the integral length is 80 ns.

Key words: Plastic scintillation, Coincidence time window, Detection efficiency of real event, PSD window, Energy resolution
