摘要
为了应用BC501液体闪烁探测器测量脉冲信号时间序列,利用252Cf裂变γ射线和中子飞行时间谱,测量了两种大小BC501探测器对裂变瞬发射线的响应。探测器对入射γ射线的定时精度能够达到1.2 ns。获得了平均一次252Cf裂变,不同中子能量阈值以上,γ射线和中子的绝对计数。
To apply the BC501 detector to pulse time sequence measurement, two different size detector responses are measured to instantaneous rays from 252 Cf fission. The time spectra of flight of γ- ray and neutron from 252Cf fission are utilized. The γ- ray timing precision of BC501 detector can reach 1.2 ns. The absolute counts of γ- ray and neutron are obtained per fission above different neutron energy thresholds.
