NA62 RICH的光探测系统和时间分辨率
Light Detection System and Time Resolution of the NA62 RICH
摘要:
在NA 62中使用了一个大型的RICH探测器,以在15和35 GeV/c之间的动量范围内将带电π介子样品中的μ子污染抑制100倍。切伦科夫光由放置在上游端的1952光电倍增管收集。本文描述了光电倍增管的特性以及专用前端和数据采集电子学,给出了时间分辨率和光探测效率的测量。
英文摘要:
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.
