mDOM - a multi-PMT optical module for future upgrades of IceCube — •Lew Classen, Tabea Eder, Daniel Guderian, Alexander Kappes, Cristian Lozano, Florian Sprenger, Florian Trittmaack, and Martin Unland for the IceCube collaboration — Institut für Kernphysik, Westphälische Wilhelms-Universität Münster

Following the discovery of a high-energy astrophysical neutrino flux by IceCube research and development for a next-generation neutrino observatory in Antarctica is under way. A significant relative enhancement in sensitivity for the envisionend detector is expected from novel optical sensors. Among the most promising new designs is the so-called mDOM, a multi-PMT Digital Optical Moule. Optical modules based on this concept feature an array of several small photomultipliers (PMTs) housed inside a transparent pressure vessel, resulting in several advantages with respect to the conventional single-PMT design, such as a larger sensitive area, a uniform solid angle coverage as well as enhaced intrinsic directional senisitivity. The contribution will introduce the sensor concept and provide an overview of the current status of development of the device.
