含硼液体闪烁体在中子探测方面具有许多优良特性,由于10B具有高的慢中子俘获截面,氢具有高的快、慢中子散射截面,因此能够实现对慢中子和快中子的同时探测。为有效区分中子和γ事件,用过零时间法对含硼液体闪烁体BC501的n-γ甄别能力进行了实验测量。结果表明,脉冲时间
Boron-containing liquid scintillators have many excellent properties in neutron detection. Since 10B has a high slow-neutron capture cross-section, hydrogen has a high fast and slow neutron scattering cross-section and thus can achieve high neutron and fast neutron Simultaneous detection. In order to effectively distinguish between neutrons and γ events, the n-γ screening ability of boron-containing liquid scintillant BC501 was experimentally measured by the zero-crossing time method. The results show that the pulse time
