A multi-PMT Optical Module for the IceCube Upgrade — •Alexander Kappes for the IceCube collaboration — Institut für Kernphysik, Westfälische Wilhelms-Universität Münster, Münster

The IceCube Upgrade will add about 700 new advanced optical sensors to the current detector, thereby expanding its capabilities both at low and high neutrino energies. A large fraction of the upgrade modules will be multi-PMT Digital Optical Modules, mDOMs, each featuring 24 three-inch class photomultiplier tubes (PMTs) pointing uniformly in all directions. Together, the 24 PMTs provide an effective photosensitive area more than twice than that of the current IceCube optical module. The main mDOM design challenges arise from the constraints on the module size and power needed for the 24-channel high-voltage and readout systems, as well as the extreme environmental conditions in the deep ice at South Pole. This contribution presents an overview of the module design and the current development status.
