Lateral distribution study for the IceTop scintillator array — •Agnieszka Leszczyńska1, Aswathi Balagopal V.1, Andreas Haungs1, Thomas Huber1,2, Donghwa Kang1, and Max Renschler1 for the IceCube-Gen2 collaboration — 1KIT, Karlsruhe, Germany — 2DESY, Zeuthen, Germany
IceTop, a surface component of IceCube, is planned to be upgraded with a prospective scintillator array. As a first motivation, the enhancement will provide a reference signal for the IceTop Cherenkov detectors improving the accuracy of shower reconstruction. In the long term it is foreseen to constitute a large veto array discriminating the astrophysical neutrino signal from an atmospheric background. The accompanying improvement of the air-shower measurements has to be preceded with detailed studies of the foreseen array. The generic simulations allow to obtain a parameterization for the particle lateral distributions in the air showers. In addition, more precise simulations of a deposited energy were performed for a deployed prototype module. The proper description of particle lateral distributions registered by scintillation detectors can significantly improve the reconstruction process and optimization of cosmic-ray parameters. This talk will show a simulation study of air-shower properties reconstructed by the proposed scintillator array.
