Abstract Objective Based on the wavelength-shifting fibers and Zns(Ag)/H310Bo3 scintillation screen, we developed a neutron position sensitive detector.Methods We established the apparatus using wavelength shifting fibers and ZnS(Ag)/H310BO3 scintillation screen capture neutron, silicon photomultiplier array, "pattern match" method to determine neutron position. Then neutron source and neutron flux from nuclear reactor was used to test the characters of the system.Rusults The detector has the sensitive area of 80 mm×80 mm, pixel of 5 mm,detection efficiency of 4.4%±0.2% and count ability of 104/s.Conclusion The output of the thesis can fulfill the needs of neutron spectrum for the research in different scientific fields.
