Abstract

Abstract

To solve the shortcomings of traditional neutron detectors in neutron detection in complex environments such as narrow space, strong electromagnetic interference, and long-distance transmission, this study combines ⁶LiF/ZnS(Ag) mixed materials and scintillating fiber to design a new type of scintillator fiber neutron detector that can be used for wide energy spectrum neutron measurement. Based on the FLUKA software, the neutron detection performance of the new fiber neutron detector was simulated and the optimization design of the scintillator fiber probe was completed. The results show that when the energy of the incident neutron is 0.01~10eV and 0.5~10MeV, the new neutron detector has a high neutron detection efficiency, it can detect the neutron in the wide spectrum of thermal neutron and fast neutron. In addition, by comparing the difference in pulse amplitude, the new neutron detector can realize the discrimination of n-γ signals.
