A simulation study of possible detector geometries for the future IceCube extension IceCube-Gen2 — •Richard Konietz, Jacob Leuner, Jan Auffenberg, Christian Haack, and Christopher Wiebusch for the IceCube collaboration — 3. Physikalisches Institut B, RWTH Aachen

The discovery of high-energy neutrino sources would be a major breakthrough for astroparticle physics, as they are expected to be connected to the sources of cosmic rays. The IceCube Neutrino Observatory, a cubic-kilometer-sized neutrino telescope at the geographic South Pole, has discovered a diffuse neutrino flux. Even after four years of data taking no indication for point sources has been found. To significantly increase the chance of identifying sources of high-energy neutrinos, a larger detector is needed. We study possible geometries for the future IceCube extension IceCube-Gen2, which is planned to instrument a volume about an order of magnitude larger than IceCube. In this study, the geometry is optimised for a single connected detector with a maximised projected area and an optimal angular resolution.
