Abstract：
A photon detector is composed of CeF₃ (Cerium Fluoride) scintiplator and high current photomultipler tube (PMT). The experiment results indicate that the sensitivity of this detector is about 0.6 and 0.1 with respect to that of usual plastic scintillator ST 401, for ⁶⁰Co γ and pulse DT neutron radiation, respectively. The biggest linear current of this detector is above 1.5 A, dark current is lower than 10nA. This kind of detectors is gamma pulse radiation detectors insensitive to neutron radiation with large dynamic range.
