The IceCube Neutrino detector at the South Pole uses more than a billion tons of natural ice as a target for neutrino detection.IceCube detects more than 100,000 neutrinos per year from GeV to PeV energies. While most of them originate from cosmic rays hitting the Earth’s atmosphere, IceCube has identified a flux of neutrinos above 100 TeV that is predominately of cosmic origin. I will discuss the detector, the analysis of the data and the findings obtained, as well as new strategies to extract more information. Plans for next generation neutrino detector optical and radio detectors, IceCube-Gen2 and ARA will be presented.
Albrecht Karle is the IceCube Associate Director for Science and Instrumentation, the Principal Investigator for ARA, and a professor of physics at the University of Wisconsin–Madison. His research is focused on high-energy neutrino astronomy and astrophysics. With IceCube, he focuses on research with neutrinos of all flavors at energies above 30 TeV. He is also exploring new ways to detect ultra-high-energy neutrinos using radio detectors. Karle currently serving as the department chair.
