A versatile PMT test bench and its application in the DAMPE-PSD

A versatile test bench system, dedicated for massive PMT characterization, is developed at the Institute of Modern Physics, Chinese Academy of Sciences. It can perform many test contents with large capacity and high level of automation, and the migration from one testing configuration to another is lightweight and time-saving. This system has been used in the construction of the Plastic Scintillator Detector of DArk Matter Particle Explorer already, and a total of 570 Hamamatsu R4443 tubes have been tested successfully.
