The mDOM - a multi-PMT optical module for the IceCube Upgrade — •Martin Antonio Unland Elorrieta for the IceCube collaboration — Institut für Kernphysik, Westfälische Wilhelms-Universität Münster, Münster

The IceCube detector at the South Pole, currently the largest neutrino observatory worldwide, is being upgraded with seven new strings. New sensors with increased sensitivity have been developed for this project, the IceCube Upgrade. More than half of the modules installed will be Multi-PMT Digital Optical Modules (mDOMs), which feature 24 isotropically aligned photomultipliers (PMTs) in a pressure vessel. This design provides, among other things, an effective photosensitive area more than twice that of IceCube's current optical sensor, near-uniform angular coverage, and the ability to exploit local coincidence between PMTs of the same module. The presentation provides an overview of the module design.
