Updates on the optical module for IceCube-Gen2 — •Markus Dittmer and Alexander Kappes for the IceCube-Gen2 collaboration — Universität Münster, Institut für Kernphysik

As part of the further development of IceCube, an innovative optical module (OM) was developed for IceCube-Gen2, which builds on the successful features of the mDOMs and D-Eggs of IceCube Upgrade, but also adapts to the limitations of the smaller borehole diameter. This new OM design, which will be tested in IceCube Upgrade, will serve as a prototype for the planned mass production of 10,000 OMs for IceCube Gen2. To simplify the assembly processes, important changes had to be made to the design, especially to integrate the gel pad concept. In this presentation, the design philosophy will be reviewed and various performance metrics will be presented.
