    Graphical Abstract
    • Abstract
  • The cerium fluoride(CeF3) is a kind of new fast time response inorganic scintillator. The physical characteristics of CeF3 are well suitable for detection of domestic pulse γrays. The time response of detector composed by phototube with CeF3 are measured by use of the pulse radiation source with rise time about 0.8 ns, and FWHM time 1.5～2.2 ns. Experiment results show that the rise time is less than 2 ns, FWHM time is about 10 ns, fall time is about 60 ns, average decay time constant is 20～30 ns,respectively for CeF3.
