Prospects and Techniques of Surface Detector Extensions for IceCube — •Jan Auffenberg for the IceCube-Gen2 collaboration — III. Physikalisches Institut B, RWTH Aachen University

The discovery of astrophysical neutrinos up to PeV energies by the IceCube Observatory has triggered intense interest in identifying their origin. Therefore, to improve IceCube's neutrino detection- and overall capabilities, IceCube-Gen2 is planned. For neutrino astronomy, a large background-free sample of well-reconstructed astrophysical neutrinos is essential. The main background for this signal are muons and neutrinos which are produced in cosmic-ray air showers in the Earth's atmosphere. The coincident detection of these air showers by the surface detector IceTop has been proven to be a veto for atmospheric neutrinos and muons in the field of view of the Southern Hemisphere. This motivates a large extension of IceTop to more efficiently detect cosmic rays. In addition, the measurement of different signal channels of air showers is a powerful tool to improve gamma ray detection and cosmic ray composition studies with IceCube. The different channels can be: the high energy muon detection by IceCube deep in the ice, the particle detection on the surface, air Cherenkov light detection, or radio signals of air showers. A selection of technologies, like the usage of imaging air Cherenkov telescopes, IceAct, radio signal detection of air showers, or particle detection with scintillator paddles is discussed.
