论文摘要
使用线性烷基苯（LAB）作为主要溶剂，为液体闪烁液溶液提供了四个高效，缓慢的荧光的时间和光谱特性。这些混合物表现出高光的产量，但在数十ns的顺序上增加了几个或更多的ns和衰减时间。因此，这种液体闪烁体的混合物可用于基于大规模液体闪烁探测器中的时间安排的Cherenkov和闪烁成分的有效分离。这种分离在这里以延伸到1 meV以下的能量的电子为基准尺度上的基准尺度上证明了这种分离。这可能会对这种检测器的未来开发产生重大影响，以测量太阳中微子和中微子双β衰变，并为来自超新星中微子和反应堆抗神经酮的弹性散射事件提供良好的方向信息。
The timing and spectral characteristics of four highly efficient, slow fluors are presented for liquid scintillator solutions using linear alkylbenzene (LAB) as the primary solvent. The mixtures exhibit high light yields, but with rise times of several ns or more and decay times on the order of tens of ns. Consequently, such liquid scintillator mixtures can be used for effective separation of Cherenkov and scintillation components based on timing in large scale liquid scintillation detectors. Such a separation, showing high light yield and directional information, is demonstrated here on a bench-top scale for electrons with energies extending below 1 MeV. This could have significant consequences for the future development of such detectors for measurements of solar neutrinos and neutrinoless double beta decay as well as providing good directional information for elastic scattering events from supernovae neutrinos and reactor anti-neutrinos, amongst others.
