First results with the Station 0 of the IceCube Surface Array Enhancement — •S. Shefali for the IceCube collaboration — Institut für Astroteilchenphysik, Karlsruher Institut für Technologie (KIT), Karlsruhe, Germany

The IceCube Neutrino Observatory is a multipurpose detector which includes a unique surface array, IceTop, highly instrumental for cosmic ray studies in addition to its capability of vetoing for astrophysical neutrino searches for the IceCube in-ice instrumentation. It consists of frozen water tanks equipped with photomultipliers instrumented to detect secondary particles like electrons, protons and muons from cosmic ray air showers of energies up to 1 EeV.
An enhancement of the surface array, with scintillation and radio detectors, in order to facilitate multi-component cosmic ray studies, as well as improving the IceTop detectors’ calibration by accounting for the snow accumulation on them, has been ongoing. The existing prototype station was recently upgraded to the first working station of the enhancement, "Station 0". This contribution will discuss the upgrade, and the first air shower measurements conducted with this station.
