LOM: An optical module for IceCube-Gen2 — •Anna Weatherburn, Lew Classen, and Alexander Kappes for the IceCube collaboration — Institut für Kernphysik, Westfälische Wilhelms-Universität Münster, Münster

IceCube-Gen2 will further the research done by IceCube and the IceCube Upgrade into cosmic high energy neutrinos. The next generation of IceCube will attempt to identify the sources responsible for these cosmic high energy neutrinos, extend the energy spectrum of measured neutrinos and take measurements of the neutrino flavour ratio. For this high-energy array upgrade, about 10,000 additional optical sensors on 120 strings will be installed, thereby extending its size to about 8 km3. The optical module technology for Gen2 is currently under development, and one of the most promising candidates is the LOM (or Long Optical Module). The LOM design consists of many small photomultipliers (PMTs), similarly to the mDOM (multi-PMT Digital Optical Module) used in the IceCube Upgrade. However the diameter will be reduced in order to substantially reduce the cost and time of drilling to place the optical modules. The particular design of the LOM will be determined through simulations and consideration of the practicalities of design features. An overview of the current status of simulations and optimisation studies of the optical properties of the new module will be given.
