论文摘要
大规模液体闪烁体检测器的构造使闪烁区域与光电倍增管（PMTS）的需求由于其内在的放射性而变得复杂。这通常是使用丙烯酸或尼龙屏障进行的，其自身的活性也可能导致许多低能量（MEV）研究的基准检测量大幅减少，并且对于较大的检测器体积而言，其构造变得越来越困难且昂贵。在这里，我们提出了一种称为滑动的替代几何结构（分层液体平面闪烁体）的初步模拟研究，该研究旨在完全避免使用这种物理屏障，而是使用脂肪液液层将PMT与闪烁区分开。
The construction of large-scale liquid scintillator detectors is complicated by the need to separate the scintillation region from photomultiplier tubes (PMTs) due to their intrinsic radioactivity. This is generally done using acrylic or nylon barriers, whose own activity can also lead to substantial reduction of the fiducial detection volume for a number of low energy (MeV) studies, and whose construction becomes increasingly difficult and expensive for larger detector volumes. Here we present an initial simulation study of an alternative geometric construction known as SLIPS (Stratified LIquid Plane Scintillator), which aims to avoid such physical barriers entirely by instead using layers of lipophobic liquids to separate PMTs from the scintillation region.
