The discovery of cosmic neutrinos of TeV-PeV energies, announced by IceCube in 2013, has opened a new window to the high energy Universe. The observations made to date have already brought us closer to answering key questions, such as: what are the sources of the observed cosmic neutrinos and how do they drive particle acceleration; where are cosmic rays of extreme energies produced and how do they propagate through the universe; and are there signatures of new physics at TeV---EeV energies?
IceCube-Gen2, a next generation neutrino observatory, is designed to address these questions. In conjunction with continued progress in multi-messenger astrophysics, IceCube-Gen2 promises to elevate the field of cosmic neutrinos from the discovery realm to the era of surveys of the neutrino sky.
IceCube-Gen2 will greatly enhance the existing IceCube detector at the South Pole. It will increase the annual rate of observed cosmic neutrinos by an order of magnitude, and will be able to detect sources five times fainter. Furthermore, through the addition of a radio array, IceCube-Gen2 will extend the sensitive energy range beyond EeV energies. The design of IceCube-Gen2 greatly profits from the available experience gained through IceCube and from additional improvements in technology.
