Measuring the capability of resisting 14 MeV neutron yawp of domestic LaCl₃ scintillator

When measuring γpulse in 14 MeV neutron radiation field with LaCl₃ scintillator, the γ sensitivity is necessarily know. At the same time, the capability of resisting 14 MeV neutron yawp should also be necessarily know, too. In this paper, the γ sensitivities of LaCl₃ and CeF₃ are measured in steady γ radiation field, and the neutron sensitivities of both are measured in 14 MeV pulse neutron radiation field which FWHM is about 10-6 s. The capability of resisting 14 MeV neutron yawp of LaCl₃ scintillator is calculated according to that of CeF₃ scintillator. The result shows that the capability of resisting 14 MeV neutron yawp of LaCl₃ is comparative with that of CeF₃. The ratio of above results adopting electric charge method is 1, the ratio of above results adopting peak value method is closely 2. The ratio of capability of resisting 14 MeV neutron yawp of LaCl₃ and ST401 is more 10. (authors)
