摘要：
In this research, based on pulse reconstruction method, digital storage oscilloscopes with an 8-bit digital-to-analog convertor was used to successfully perform the neutron-gamma discrimination with NE213 (or its equivalent BC501A) scintillator anode pulses at minimum discrimination bias value of 95 keVee (or keV electron equivalent). Also, a 100 mCi Am-241-Be source and micro-Curie gamma ray sources (Cs-137 and Na-22) were used for the system calibration and discrimination studies. The results confirm the feasibility and simplicity of the proposed method. (C) 2014 Elsevier Ltd. All rights reserved.
