Li Co-Doped NaI:Tl (NaIL)—A Large Volume Neutron-Gamma Scintillator With Exceptional Pulse Shape Discrimination

We have demonstrated that Li can be substantially incorporated into the matrix of NaI under an optimized crystal growth process. The incorporation of Li introduces efficient neutron detection into an already successful commercial gammaray scintillator. Exceptional gamma-neutron pulse shape discrimination (PSD) has been demonstrated in Li co-doped NaI:Tl crystals with up to 8% Li concentration. Neu...
