大质量光电倍增管（PMT）的性能表征是大型核实验和粒子实验中经常遇到的问题。为了促进这项工作，中国科学院近代物理研究所开发了一个专用的测试台系统。二维光电阴极位置扫描能力是测试台的固有功能，最多可同时测试25个直径小于2″的光电倍增管。光源脉冲的参数可以在很宽的范围内调节，从而使其适合于各种特性测量。测试台系统高度自动化，所有控制操作都集成到一个软件中。此外，硬件平台是可扩展的，这允许复杂的测试方案，并且软件设计中的模块化使得从一个测试配置到另一个测试配置的迁移是轻量级和高效的。所有这些特性使得该测试台具有通用性和可重复使用性。首次应用于DAMPE的塑料闪烁体探测器（PSD）的研制，成功地测试了570根滨松R4443管。本文对该系统的性能进行了验证，并给出了测试结果。
Performance characterization for massive photomultiplier tubes (PMTs) is a frequently encountered procedure in large nuclear and particle experiments. To facilitate this work, a dedicated test bench system has been developed at the Institute of Modern Physics, Chinese Academy of Sciences. The two-dimensional photocathode position scanning capability is an intrinsic function of the test bench, and up to 25 PMTs, with the diameter smaller than 2″, can be tested simultaneously. The parameters of the light source pulses can be adjusted in a wide range, thus making it suitable for various characteristics measurements. The test bench system is highly automated with all the controlling operations integrated into a single software. Additionally, the hardware platform is extensible which allows complex testing schemes, and the modularity in the software design makes the migration from one testing configuration to another light-weight and efficient. All these features make the test bench versatile and reusable in different experiments. It has been first used in the construction of the Plastic Scintillator Detector (PSD) of DArk Matter Particle Explorer (DAMPE), and a total of 570 Hamamatsu R4443 tubes were tested successfully. The performance was verified and the testing results are also reported in this article.
