| Summary: | The IceCube Neutrino Observatory (IceCube) is a cubic-kilometer neutrino detector built in the glacier ice at the South Pole. In the near future, IceCube will be extended by the IceCube Upgrade, which is the low energy extension of IceCube. This thesis focuses on characterization measurements of different system components of the multi-PMT Digital Optical Module (mDOM) for the IceCube Upgrade. The mDOM is a novel optical module using 24 small photomultiplier tubes (PMTs) instead of one large PMT. Most measurements were performed during the development stage of the mDOM before the first module was built. The following components were characterized in more detail: PMTs, analog front end (AFE), and an integrated mDOM. Different PMT types of two manufacturers were investigated during mass tests of about 150 PMTs. Based on the results of this thesis, the PMT type to be used for the mDOM was chosen, thus guaranteeing excellent directional and energy resolution of the IceCube Upgrade. Furthermore, a dedicated setup ... |
