Abstract

The thermal neutron detection efficiency

emergent light yield and γ sensitivity of EJ426 scintillator with

LiF/ZnS(Ag) blended was systemically researched. The results indicate that thermal neutron of EJ426 scintillator detection efficiency is 32.4%

emergent light yield 8.01×10

photon/neutron. When the threshold value is 70 mV

its sensitivity is less than 10

-7

which proves that it is an ideal material for scintillator-based position-sensitive neutron detectors.
