Performance of the PMT Mass Testing System for the JUNO Experiment

Not scheduled


Mr Tobias Sterr (Eberhard Karls Universität Tübingen)


The Jiangmen Underground Neutrino Observatory (JUNO) is a low
background 20 kton liquid scintillator multi-purpose experiment located in Kaiping,
Jiangmen, China. Its physics goals include the
determination of the neutrino mass ordering as well as the oscillation parameters using
reactor neutrinos. JUNO will be instrumented with approximately 20,000 20-inch
photomultiplier tubes (PMTs) of two types (dynode and micro-channel plate). These PMTs
are tested for their general performance in a PMT
testing facility located in Zhongshan, China. A major component of the testing system are
the four commercial shipping containers, which are modified and equipped with commercial
DAQ (three containers) and final JUNO electronics (one container, currently in installation),
featuring 136 channels in total. Two containers (72 channels) are used for the
characterization of each PMT. This poster presents the capabilities and performance
parameters of the containers as well as exemplary results from the PMT testing.
