Ice calibration studies for IceCube Upgrade with multi-PMT optical modules, and studies of the sensitivity of future IceCube extensions to astrophysical neutrinos in the MeV and GeV range
The IceCube neutrino observatory is a large-scale particle physics experiment at the South Pole. IceCube consists of a series of sensors embedded in the ice that detect the Cherenkov radiation produced when a neutrino interacts with the ice. Given its great success and reliability, the IceCube detec...

The IceCube neutrino observatory is a large-scale particle physics experiment at the South Pole. IceCube consists of a series of sensors embedded in the ice that detect the Cherenkov radiation produced when a neutrino interacts with the ice. Given its great success and reliability, the IceCube detector is being expanded through two extension projects: IceCube Upgrade and IceCube-Gen2. The IceCube Upgrade project aims to install ∼700 new optical modules in a dense configuration in the existing IceCube volume to detect low-energy neutrinos; construction is planned for the Australian summer of 2025-2026. IceCube-Gen2 envisions an expansion of the instrumented volume from 1 to 8 km 3 with new optical modules. Construction is scheduled to begin shortly after the completion of IceCube Upgrade. This expansion will allow IceCube to significantly increase its detection rate of cosmic high-energy neutrinos and further improve our understandingof the universe.
