论文摘要
在Na62中使用了大型富探测器，以抑制带电的Pion样品中的MUON污染，在15至35 GEV/C之间的动量范围内抑制100倍。 Cherenkov的光是由1952年放置在上游端的1952年光电培养基收集的。在本文中，描述了光电培养基的表征以及专用的前端和数据采集电子设备，显示了时间分辨率和光检测效率测量。
A large RICH detector is used in NA62 to suppress the muon contamination in the charged pion sample by a factor of 100 in the momentum range between 15 and 35 GeV/c. Cherenkov light is collected by 1952 photomultipliers placed at the upstream end. In this paper the characterization of the photomultipliers and the dedicated Frontend and Data Acquisition electronics are described, the time resolution and the light detection efficiency measurement are presented.
