论文摘要
我们使用来自90-SR源的Beta颗粒，研究了覆盖在波电上的波长分子的纯聚苯乙烯载玻片的光屈服，作为一种可能易于构建的，低成本的塑料塑料检测器。使用未涂层的聚苯乙烯载玻片以及未涂层和涂层的PMMA载玻片进行了比较测量，后者只能在被带电的颗粒穿过时产生Cherenkov光。与未涂层的载玻片相比，单个（双）涂层聚苯乙烯载玻片的结果显示出检测到的光子产量的4.9（6.3）倍。为了进行比较，还测量了用PTP和Popop掺杂的基于聚苯乙烯的挤出塑料闪烁体材料的光产率。绝对检测到的光产量激发了未来的研究，用于开发易于建造的低成本基于聚苯乙烯的塑料闪烁体检测器。
We studied the light yield of a pure polystyrene slide coated with wavelength-shifter molecules, coupled to a photomultiplier, using beta particles from a 90-Sr source, as a possible easy-to-build, low-cost plastic scintillator detector. Comparison measurements were performed with an uncoated polystyrene slide as well as with uncoated and coated PMMA slides, the latter which can only produce Cherenkov light when being traversed by charged particles. The results with the single (double) coated polystyrene slides show about 4.9 (6.3) times higher detected photon yield compared to the uncoated slide. For comparison, the light yield of a polystyrene-based extruded plastic scintillator material doped with PTP and POPOP was measured as well. The absolute detected light yield motivates future studies for developing easy-to-build, low-cost polystyrene-based plastic scintillator detectors.
