Characterisation of photomultipliers for KM3NeT

31 May 2018 – Each KM3NeT optical sensor module contains 31 photomultiplier tubes. Each KM3NeT detection unit comprises 18 optical modules, i.e. a total of 18 x 31 = 558 photomultipliers. Together the ARCA and ORCA detectors of KM3NeT will comprise a total of 345 detection units, i.e. 345 x 558 =192,510 photomultipliers. So, you can imagine that it is important to very well understand the characteristics of these photomultipliers. Read more
