作为COMPASS RICH-1探测器升级的一部分，已经建立了一个快速光子探测系统：它基于576个多阳极光电倍增管（MAPMTs），与单个熔融硅透镜望远镜和快速读出电子设备耦合。该系统在COMPASS RICH-1光子探测器的中心区域（1.3m2，占总面积的25%）用CsI光电阴极取代了mwpc，并在2006年和2007年的数据采集期间成功运行。介绍了快速光子探测系统的设计、建造和调试，重点介绍了透镜望远镜的设计优化和验证试验。并给出了COMPASS RICH-1升级后性能提升的初步数值。
A fast photon detection system has been built as a part of the upgrade of the COMPASS RICH-1 detector: it is based on 576 multi-anode photomultiplier tubes (MAPMTs) coupled to individual fused silica lens telescopes and fast readout electronics. This system has replaced the MWPCs with CsI photo-cathodes in the central region (1.3m2, 25% of the total area) of the COMPASS RICH-1 photon detectors and has successfully been operated during the data taking in 2006 and 2007. We report about the fast photon detection system design, construction and commissioning, in particular about the design optimization and the validation tests of the lens telescopes. Preliminary values for the increased performances of COMPASS RICH-1 after the upgrade are also presented.
