The elpasolite crystal CLLB is proposed to detect both γ-ray and thermal neutron events with the ability to distinguish them by pulse shape discrimination (PSD) method. Pulse shapes of γ-ray, alpha particle, thermal and fast neutron events were measured and determined that PSD can be performed to separate γ-ray from alpha and thermal neutron events with a Figure of Merit (FoM) 1.23. The γ-ray non-proportional response is less than 2% in the energy region of 59.6 keV–4438 keV. Fast neutron responses for CLLB scintillator were investigated and analyzed using deuterium tritium (DT) reaction neutrons. The activity of 511 keV γ-ray emitted by 78 Br and 80 Br can reaches up to∼ 0.709 Bq⋅ n− 1, some high-energy events at 15 MeVee–18 MeVee were found that generated according to the reaction 6 Li (n, T) 4 He.
