Investigating the time properties of an improved 3" Hamamatsu photomultiplier for the KM3NeT Neutrino Telescope
Abstract
The Hamamatsu R14374-02 3-inch photomultiplier tube is an improved version of the previous R12199-02 model. It will be used for the completion of the KM3NeT neutrino telescope. Five hundred photomultipliers have been characterized for dark count rate, timing spread, and spurious pulses with a dedicated dark box apparatus.The results are compared with the model R12199 used in the first phase of construction of KM3NeT.
