New neutron detectors are being developed as demand for security applications increases. Li-containing single crystal has a significant results such as Cs2LiYCl6 (CLYC), Cs2LiLaBr6: Ce (CLLB) and LiI. Their performance of pulse shape discrimination of neutron/gamma makes it possible to detect neutron/gamma with a single material. However, there is difficulty such as material cost, handling, complexity and hygroscopic in crystal growth. In particular, CsI(Tl) crystal scintillator doesn-t have such difficulty with good scintillation performance. Therefore, we developed Li co-doped CsI(Tl) crystal scintillator for neutron detection. Thermal neutron detection is realized by the 6Li(n,t)α neutron capture reaction. The reaction products, an alpha particle and a triton, deposit a total of 4.8 MeV energy in the crystal. In this poster, Li co-doped CsI(Tl) single crystals have been studied with optical scintillation properties and neutron/gamma capabilities
