Simulation study for an extended IceTop Detector for IceCube-Gen2 — •Agnieszka Leszczyńska1, Aswathi Balagopal V.1, Andreas Haungs1, and Thomas Huber1, 2 for the IceCube collaboration — 1KIT, Karlsruhe, Germany — 2DESY, Zeuthen, Germany

The next generation of the IceCube experiment will be a powerful high-energy neutrino detector, sensitive to resolve the sources of astrophysical neutrinos. The new facility will be able to measure the GZK neutrino flux providing also information about the composition of the highest energy cosmic-rays. The big challenge of the measurements is here to discriminate the astrophysical signal from the atmospheric background. This can be resolved by a large surface extension of present IceTop with scintillation detectors. If the in-ice event is detected in coincidence with the air-shower signal at the surface detectors it can be vetoed obtaining only the astrophysical neutrinos. The first step is the enhancement of IceTop in the present area, which will also improve the cosmic-ray composition measurements of IceCube. This talk will show a simulation study for the first phase of the deployment of scintillator detectors.
