【摘要】:A position-sensitive detector is designed for neutron detection.It uses a single continuous screen of a self-made lithium glass scintillator,rather than discrete crystal implementations,coupling with a multianode PMT(MaPMT).The scintillator is fast and efficient;with a decay time of 34 ns and thermal neutron detection efficiency of around 95.8% for the 3 mm thick screen,and its light yield is around 5670 photons per neutron and 3768 photons per MeV γ rays deposition.The spatial resolution is around 1.6 mm(FWHM) with the energy resolution around 34.7% by using α(5.2 MeV) rays test.
