Investigation of the potential of composition measurements with IceTop and IceAct — •Aatif Waza, Jan Auffenberg, Thomas Bretz, Thomas Hebbeker, Jan Paul Koschinsky, Tim Niggemann, Martin Rongen, Tobias Sälzer, Merlin Schaufel, and Johannes Schumacher for the IceCube collaboration — III. Physikalisches Institut, RWTH Aachen University, D-52056 Aachen, Germany

IceAct is planned as an array of SiPM-based Imaging Air Cherenkov Telescopes as one surface component of IceCube-Gen2. Goal of this array would be to efficiently detect cosmic rays below the threshold of IceTop and improve composition measurements of the IceCube Neutrino Observatory. Within the hybrid measurement of cosmic rays by IceTop, IceCube, and IceAct, IceTop mainly provides the direction and energy of the shower, IceCube a measurement of the high-energy muon component, and IceAct the particle density along the air shower axis. We present first results from CORSIKA-based simulations of air showers with proton and iron primary particles.
