Performance of IceTop enhancement with scintillator array — •Agnieszka Leszczyńska1, Aswathi Balagopal V.1, Andreas Haungs1, Donghwa Kang1, Marie Oehler1, Max Renschler1, Thomas Huber1,2, and Fiona Ellwanger1 for the IceCube collaboration — 1KIT, Karlsruhe, Germany — 2DESY, Zeuthen, Germany

One of the proposed upgrade of IceTop, a surface component of Ice-Cube, will comprise of the scintillation detectors arranged within the present IceTop area. The proposed array will enhance the cosmic-ray measurements and provide an improvement in the background discrimination for the astrophysical neutrino detection in the southern hemisphere sky. The scintillation detectors, due to their complementary response to the air-shower components with respect to the Cherenkov tanks, can boost the current discrimination of the primary cosmic-ray mass.

We conducted a detailed simulation study on the capabilities of the enhanced array in terms of trigger probability and air-shower reconstruction. Moreover an investigation of a possible parameter which is sensitive to the cosmic-ray mass was performed.
