标题： Series Testing and Characterization of 1100 Hamamatsu H12700 Multianode Photomultiplier Tubes

摘要： 两种未来的CBM-RICH和最近升级的HADES-RICH都使用Hamamatsu H12700多阳极光电倍增管（MAPMTs）作为其光子探测器。 在将这些MAPMTs用于探测器之前，对它们进行了彻底的测试，光子传感器提前得到了认证，并建立了一个测试台以高效地表征每个MAPMT。 测试台测量每个通道的单光子增益、暗计数率、相对效率和后脉冲概率。 本文描述了测试台的工作原理，并讨论了1,100个MAPMT中每个测量量的分布情况。 此外，基于对单个MAPMT的重复测量，研究了H12700 MAPMT的长期老化效应。 显示英文摘要

摘要： Both the future CBM-RICH and the recently upgraded HADES-RICH use Hamamatsu H12700 Multi-Anode Photomultipliers (MAPMTs) as their photon detectors. To test the MAPMTs thoroughly before using them in the detectors, the photon sensors were qualified well in advance and a test bench was built to efficiently characterize each MAPMT. The test bench measures the single photoelectron gain, dark rate, relative efficiency, and afterpulse probability of each channel. This article describes the operating principle of the test bench and discusses the distributions of each measured quantity over 1,100 MAPMTs. Additionally, the long-term aging effects of the H12700 MAPMT are investigated based on repeated measurements of individual MAPMTs.
