摘要
利用三通道加速器(平均能量约0.2MeV)、DPF中子源和直线拟合方法,通过实验测定和理论计算,得到了钨酸铅晶体对ST-401闪烁体的γ相对灵敏度(约为1∶2),晶体的中子与γ灵敏度之比(约为1∶6)和晶体的衰减时间(约为6ns)。
Using the γ-ray source(average energy (0.2)MeV),DPF neutron source and the linear calculation methods, the measurement results are stated. The response(compared with ST-401 crystals )to (0.2)MeVγ-ray of the PbWO_4 crystals is about 1∶2,the ratio of n/γ of the PbWO_4 crystals is about 1∶6 and the decay time of the PbWO_4 crystals is about 6ns.
