Digital neutron-gamma discrimination in a wide energy range using pulse reconstruction method

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...

Description
Summary: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 95keVee (or keV electron equivalent). Also, a 100mCi 241Am–Be source and micro-Curie gamma ray sources (137Cs and 22Na) were used for the system calibration and discrimination studies. The results confirm the feasibility and simplicity of the proposed method. •The pulse reconstruction method was utilized to perform neutron-gamma discrimination (NGD) with NE213 scintillator.•A digital storage oscilloscope with an 8-bit digital-to-analog convertor was responsible for receiving the scintillator anode pulses.•The NGD results on an Am–Be combined neutron-gamma source represents the feasibility of the proposed method.
