4，4“”-双[（2-丁基辛基）氧基]-1，1“：4”，1 "：4“，1”“-四联苯（BBQ）染料溶解在二甲苯中并富氧，显示出用于激光聚变实验飞行时间（TOF）测量的理想中子闪烁体的特性。用290 nm脉冲激发的初步结果表明，它有一个0.76 ns的快衰减分量和一个可以忽略不计的慢衰减分量或余辉。利用这种闪烁体进行飞行时间测量，我们成功地区分了核聚变产生的中子和X射线。这将极大地改善快速点火实验中的中子诊断，在快速点火实验中，中子必须在强X射线爆发的情况下被检测到。
4,4'''-Bis[(2-butyloctyl)oxy]-1,1':4',1'':4'',1'''-quaterphenyl (BBQ) dye dissolved in xylene and enriched with oxygen is shown to exhibit the characteristics of an ideal neutron scintillator for time-of-flight (TOF) measurement in a laser fusion experiment. Initial results from excitation with 290-nm pulses show that it has a 0.76-ns fast decay component and a negligible slow decay component or afterglow. By using this scintillator for TOF measurement, we have successfully discriminated between nuclear fusion-generated neutrons and X-rays. This would dramatically improve neutron diagnostics in fast ignition experiments where neutrons have to be detected in the presence of an intense X-ray burst.
