IceTop, the surface array of the IceCube Neutrino Observatory, currently consists of 162 ice Cherenkov tanks and is used for the detection of air showers, besides being used as a veto and calibration device for the in-ice neutrino detector. The analyses of the IceTop data have led to many important results in cosmic ray physics. The science case of IceTop can be further enhanced by complementing the existing detector with an array of radio antennas and scintillator panels. Due to the unique location at the geographic South Pole and the radio-quite environment, the radio antennas are expected to provide an excellent characterisation of the electromagnetic shower component. This will help us identify primary particle mass and give us a good sensitivity to inclined air showers, in particular interesting for those arriving from the direction of the Galactic Centre. As a test for the deployment of the full array, a first prototype station with scintillator panels and two radio antennas has been deployed at the Pole in January 2019. The data collected from this station has been crucial for giving us a better understanding of the radio background at the IceTop site, giving us a more realistic estimate of the future array performance and helping us with design decision for the final array hardware. ... mehrIn this talk, I will show the background measurements obtained from the prototype station and give a summary of the analysis results.
