Abstract

Photomultiplier tube (PMT) modules were selected to read out the signals in the BGO electromagnetic calorimeter for the Dark Matter Particle Explorer satellite. The test procedure and the related quality control of mass production PMT modules are described, with a summary of PMT module quality and the results from tests. With strict quality control throughout the production and test process, over 88% of the PMT modules meet the criteria required by DAMPE.
