COMPASS is a fixed target experiment at CERN SPS aimed to study hadron structure and spectroscopy. Hadron identification in the momentum range between $3$ and $55 GeV/c$ is provided by a large gaseous Ring Imaging Cherenkov Counter, RICH-1. To cope with the challenges imposed by the new physics program of COMPASS, RICH-1 has been upgraded by replacing four MWPC-based photon detectors with newly developed MPGD-based photon detectors. The architecture of the novel detectors is a hybrid combination of two layers of THGEMs and a Micromegas. The top of the first THGEM is coated with CsI acting as a reflective photo-cathode. The anode is segmented in pads capacitively coupled to the APV-25 based readout. The new hybrid detectors have been commissioned during the 2016 COMPASS data taking and stably operated during the 2017 run. In this paper design, construction, operation and performance aspects of the novel photon detectors for COMPASS RICH-1 are discussed.
The MPGD-Based Photon Detectors for the upgrade of COMPASS RICH-1 and beyond
在RD26合作中使用MWPC中的CsI固态光电阴极为RICH应用开创了单光子气体探测器之后，并在CERN SPS的COMPASS实验中构建了RICH探测器，2016年，我们通过基于MPGD技术的新型气体光子探测器升级了COMPASS RICH。为了满足COMPASS物理计划对效率和稳定性的挑战性要求，已经安装了四个新型光子探测器，总有效面积为1.5 m $^2$。这些探测器是基于MPGD的单光子探测器实验中的第一个应用。介绍了升级的各个方面，包括工程设计、批量生产、质量评估和性能。展望了气体单光子探测器领域的进一步发展。

本次提交的重点是微图案气体探测器（MPGD）技术的进步和优势，以及它们在建造专用时间投影室（TPC）方面的应用，TPC可作为任何多用途探测器的优秀主跟踪器，可预见在未来的轻子对撞机上运行。报告的第一部分是执行摘要。随后将详细介绍MPGD在ILC ILD LCTPC建设、SuperKEKB Belle II探测器可能升级以及CEPC探测器TPC设计中的应用。MPGD技术提供了与其他探测器研发和几个应用领域的协同作用;将在美国正在进行的Snowmass长期规划工作的背景下提供一些例子。在适当的时候，将强调与美国机构的工业伙伴关系和工作的联系。
