Measurement and application of Be(d, n) reaction neutron source

The neutron energy spectra of Be(d, n) reaction source for deuteron energy of 20 MeV at an angle of 0° was measured using time-of-flight techniques and the n-γ discrimination properties of a BC501A liquid scintillation detector. The energy range of the whole neutron spectra measured in the experiment was 0.7 MeV to 25.0 MeV. The fluence of neutron beam was determined by a stilbene scintillation detector which was normalized to the well-calibrated BC501A liquid scintillation detector. Based on the Be (d, n) reaction neutron source, the neutron response of a thin plastic scintillation detector in the energy range of 0.75 MeV to 15.75 MeV was measured by single particle method. The results obtained from the experiment agree with Monte Carlo simulations considering the relative uncertainty o
