Abstract
In this paper, we determined the scintillation and thermoluminescence properties of $Cs_2NaCeBr_6$ elpasolite scintillation crystal. The emission spectrum of $Cs_2NaCeBr_6$ is located in the range of 300 ~ 450 nm, peaking at 377 nm and 400 nm. And, the fluorescence decay time of the crystal is composed two components. The fast component is 140 ns (94%), and the slow component is 880 ns (6%) of the crystal. The after-glow is caused by the electron and hole traps in the crystal lattices. We determined thermoluminescence parameters of the traps in the crystal. The determined activation energy(E), kinetic order and frequency factor of the traps are 0.67 eV, 1.71 and $2.51{\times}10^8s^{-1}$ respectively. In this crystal, re-combination rate is more dominant phenomenon than the re-trapping rate.
