在RD26合作项目中，在mwpc中使用CsI固态光电阴极为RICH应用开发了单光子气体探测器，并在CERN SPS中构建了COMPASS实验的RICH探测器，2016年，我们利用基于MPGD技术的新型气体光子探测器升级了COMPASS RICH。安装了四个新型光子探测器，覆盖1.5平方米的总活动面积，以应对COMPASS物理方案具有挑战性的效率和稳定性要求。这是基于mpgd的单光子探测器在实验中的首次应用。介绍了升级的各个方面，包括工程、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。
After pioneering gaseous detectors of single photon for RICH applications using CsI solid state photocathodes in MWPCs within the RD26 collaboration and by the constructions for the RICH detector of the COMPASS experiment at CERN SPS, in 2016 we have upgraded COMPASS RICH by novel gaseous photon detectors based on MPGD technology. Four novel photon detectors, covering a total active area of 1.5 m2, have been installed in order to cope with the challenging effciency and stability requirements of the COMPASS physics programme. They are the first application in an experiment of MPGD-based single photon detectors. All aspects of the upgrade are presented, including engineering, mass production, quality assessment and performance. Perspectives for further developments in the field of gaseous single photon detectors are also indicated.
