论文摘要
Super Tau-Charm设施（STCF）是在Tau-Charm能量区域运行的未来电子位置对撞机，旨在研究强子结构和光谱法。戒指成像Cherenkov计数器（Rich）提供了最高2 GEV/C的STCF枪管颗粒识别（PID）检测器的基线设计。富人的结构是一种近似聚焦的设计，液体全氟己烷在石英容器中密封为散热器，以及Thgems的CSI涂层层和微瘤层的CSI涂层层的混合组合，作为光电子检测器。在DESY建造并测试了具有石英散热器的16*16 cm^2原型。它以10^5的有效增益稳定地运行。在本文中，讨论了在富检测器方面的设计，性能，重建算法和单个光子电子角分辨率的系统误差。
Super tau-Charm facility(STCF) is a future electron-position collider operating at tau-Charm energy region aimed to study hadron structure and spectroscopy. The baseline design of the STCF barrel particle identification(PID) detector in the momentum range up to 2 GeV/c is provided by a Ring Imaging Cherenkov Counter(RICH). The architecture of the RICH is an approximately focusing design with liquid perfluorohexane sealed in the quartz container as radiator and a hybrid combination of a CsI coated layers of THGEMs and a Micromegas as the photo-electron detector. A 16*16 cm^2 prototype with quartz radiator has been built and tested at DESY. It was stably operated with 10^5 effective gain. In this paper, the design, the performance, the reconstruction algorithm and the systematic error for single photon electron angular resolution in the aspect of RICH detectors are discusses.
