论文摘要
利用液体氩气电离颗粒（LAR）产生的闪烁光（LAR）产生的粒子检测系统已在CERN组装。该系统基于10个浸入充满液体氩气的1500升露水浸入液中的大面积光电倍增管（PMT），并配备了对Alpha源的可扩展进料和机械支持（241AM）。可以在垂直和水平方向上相对于PMT平面更改源的位置。集成在源支持中的硅光电倍增仪（SIPM）光电探测器的阵列用于数据采集触发器并定义光生成的T0。 PMT和SIPM信号可以在不同的距离和不同位置记录，以允许测量某些LAR闪烁的光特性。对该系统进行了详细研究并进行了详细的特征，并且预计很快就会就LAR闪烁性能进行物理结果。
A particle detection system that exploits the scintillation light produced by ionizing particles in liquid argon (LAr) has been assembled at CERN. The system is based on 10 large-area photomultiplier tubes (PMT) immersed in a 1500-liter dewar filled with liquid argon and equipped with an extendible feed-through and mechanical support for an alpha source (241Am). The position of the source can be changed with respect to the PMT plane in vertical and horizontal directions. Arrays of silicon photomultiplier (SiPM) photodetectors, integrated in the source support, are used for the data acquisition trigger and to define the t0 of the light generation. PMT and SiPM signals can be recorded at different distances and different positions allowing the measurement of some of the LAr scintillation light properties. The system was studied and characterized in detail, and physics results on LAr scintillation properties are expected soon.
