DD neutron relative sensitivity of cerium fluoride scintillation detector

Two kinds scintillation detectors are composed of cerium fluoride (CeF3) and ST401 with photomultiplier tube respectively, the experimental sample of CeF3 is the newly developed inorganic scintillator in China in recent years, ST401 is a common plastic organic scintillator. The DD neutron relative sensitivity of the two scintillation detectors are measured in DD neutrons source radiation field, which indicate that the DD neutron sensitivity of CeF3 scintillation detector is less than onetenth that of ST401 with same volume.
