Abstract

IceCube-Gen2 is a planned extension to the existing IceCube Neutrino Observatory currently operating at the South Pole. IceCube-Gen2 will provide an order of magnitude increase in the detection rate of cosmic neutrinos by deploying ∼10,000 novel sensors deep in the glacial ice. The IceCube-Gen2 sensor comprises up to eighteen photomultiplier tubes (PMTs) read out with custom electronics. The PMTs are mounted inside a borosilicate glass pressure vessel and optically coupled via “gel pads” to increase the probability of photon capture. The use of multiple PMTs provides coverage in every direction, aiding in event localization and reconstruction. The tight constraints on the in-ice borehole size, coupled with power constraints for instrumentation at the South Pole, presents several design challenges. Prototypes of the IceCube-Gen2 optical module are currently under development, and several will be deployed as part of the IceCube Upgrade. In this contribution, we will provide an overview of IceCube-Gen2 with a specific focus on the optical module currently under development.
