摘要：

LiCaAlF6 scintillators are one of the attractive scintillators for neutron detection. To reduce the effect on gamma-rays, the Ce doped LiCaAlF6 scintillators can discriminate the neutron and gamma-ray events based on the pulse shape discrimination technique. To apply the scintillators for the oil logging, the high temperature characteristics must be investigated. In this paper, the temperature dependence of the neutron-gamma discrimination based on pulse shape discrimination technique in the Ce : LiCaAlF6 scintillator is investigated as one of the high temperature characteristics. The property of pulse shape discrimination in the Ce : LiCaAlF6 has small temperature dependence ranging from 25 degrees C to 150 degrees C. We concluded that the Ce : LiCaAlF6 scintillators can discriminate neutron and gamma-ray events under high temperature condition up to 150 degrees C.
