Design and commissioning of a PMT testing facility for the IceCube Upgrade mDOM PMTs — •Lasse Halve, Robert Joppe, Martin Rongen, and Christopher Wiebusch for the IceCube collaboration — III. Physikalisches Institut B, RWTH Aachen University

The IceCube Upgrade will extend the current IceCube Neutrino Observatory with seven additional strings of instrumentation. More than 400 multiple-PMT Digital Optical Modules [mDOM], with 24 3'' Photomultiplier Tubes [PMT] each, will be deployed. All 10.000 new PMTs need to be tested for compliance with manufacturer requirements and calibrated before integration into the final modules. We present the design and commissioning of a modular test facility that allows testing ~100 PMTs at once at polar temperatures.
