Description
The IceCube Neutrino Observatory is a cubic-kilometer ice Cherenkov detector located at the geographic South Pole. Thousands of photomultipliers embedded in the deep glacial ice have been used to successfully detect and reconstruct astrophysical neutrino interactions over the last decade. This rich data set has provided evidence for several astrophysical neutrino sources, demonstrating that neutrinos are viable messengers to study these extreme environments. To further improve our abilities to observe these neutrinos, two extensions to the IceCube Neutrino Observatory are planned or in construction. In 2025/26 the IceCube Upgrade will be installed, which will consist of several new photosensor technologies in R&D to improve Cherenkov detection. It will also include an array of calibration devices that will be used to reduce systematic uncertainties for the 10+ years of data already collected. In a next step, the planed IceCube-Gen2 facility will significantly expand on the current sensitivity and observable energy range by increasing the instrumented volume, both in the ice and on the surface, and by employing the radio detection technique. In this contribution, I will describe the scientific motivation, the novel technology developed as well as the overall status of the projects.
