■概　　要
The cubic-kilometre IceCube Neutrino Detector located at the geographic South Pole is capable of precision measurements of neutrino oscillation properties by observing neutrinos produced from particle interactions in the atmosphere. To increase IceCube's sensitivity, the IceCube Upgrade will involve deploying a dense array of high-sensitivity optical modules up to 3 km deep into the Antarctic glacier at the end of this year. One of these flagship modules, the D-Egg, was developed and tested in Japan as part of an international effort, and features a factor 2.8 per-device improvement in sensitivity over the current generation detectors. With enhanced direction reconstruction and a lower energy threshold, the Upgrade is expected to probe the neutrino mass ordering at the 3 sigma level within 5 years, and observe tau-neutrino appearance after just one year of data taking. This seminar will focus on the progress of the IceCube Upgrade, including experiences during on-ice activities in the 2024/2025 Antarctic Season, and share the latest sensitivities for the IceCube Upgrade ahead of data-taking later next year.
