The research on matlab simulation and digital pulse shape discrimination for n-γ nuclear signal

Neutron radiation usually mingle with γ radiation, as a result of it, the neutron signal of radiation detector usually mix γ signal. It is significant to discriminate different nuclear signal. In this study, we use matlab to simulate n-Y nuclear pulse shape digital signal and to discriminate them by pulse shape discrimination methods, then, we discuss the discrimination effect of different method. The result shows that charge comparison method, rising time method and pulse gradient analysis are all stable and reliable for n-γ discrimination, and charge comparison method is relatively better.
