Design and preliminary results of the radio antennas array of the first complete prototype station inside IceTop footprint — •Roxanne Turcotte for the IceCube collaboration — Institut für Kernphysik (IKP), Karlsruher Institut für Technologie (KIT)

The IceTop array, located at the surface of the IceCube Neutrino Observatory, is currently used as a veto for the in-ice neutrino detection as well as a cosmic ray detector. Snow accumulated on the tanks which reduces the detector sensitivity and resolution. In order to improve those, an enhancement of IceTop is planned in the next few years which consists of an array of scintillator panels and radio antennas. Upgrading IceTop with radio antennas will improve the measurement accuracy and the field-of-view for the detection of cosmic rays, which will lead to a better estimation of the mass composition as well as a better mitigation of the atmospheric neutrino background for the in-ice neutrino. In January 2019, the first two antennas were deployed alongside seven scintillators. As a follow-up, a refurbished station with three antennas and eight scintillators, in the station layout planned for the full array, will be deployed in January 2020. This talk will focus on this prototype station. I will present the radio front-end electronics, the antenna structure and give an overview of the first data recorded by the surface antennas at the South Pole.
