Abstract：
The Combined Scintillator Detection System is compsed of Pb fiter leaf and plastic sintillator detector. Using direct current scale, the neutron sensitivity of detecion system composed of Pb fiter leaf and ST401, ST1422 and ST1423 detector,respectively has been studied at the neutron energy 0.565 MeV, 1.20 MeV, 2.50 MeV, 3.50 MeV, 5.00 MeV and 14.16 MeV. From the experiment results we get the relation of the detector's sensitivity and the thickness of Pb fiter leaf, the thickness of scintillator, and the neutrons energy. By the experiment and calculation the neutron energy response of three kinds of combined scintillator detection system is obtained.
