A commercial boron-loaded liquid scintillator EJ-339 A was studied, using a (252)Cf source with/without polyethylene moderator, to examine the possibility of discriminating slow-neutron induced events in (10)B from fast-neutron events, resulting from proton recoils, and gamma-ray events. Despite the strong light quenching associated with neutron induced events in (10)B, correct classification of these events is shown to be possible with the aid of digital signal processing.
使用带有/不带有聚乙烯慢化剂的²⁵²Cf源，对商用含硼液体闪烁体EJ - 339 A进行了研究，以检验区分¹⁰B中慢中子诱发事件与质子反冲产生的快中子事件以及伽马射线事件的可能性。尽管¹⁰B中中子诱发事件存在强烈的光猝灭现象，但借助数字信号处理表明对这些事件进行正确分类是可行的。
