　　题目：IceCube and the Discovery of Energetic Cosmic Neutrinos

　　摘要：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.
