Design and Calibration of the Surface Radio Antennas of the Prototype Station for the planned IceTop Enhancement — •Roxanne Turcotte for the IceCube collaboration — Institut für Astroteilchenphysik, 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. Over the years, snow accumulated on the IceTop detector which has reduced the sensitivity and resolution. In order to improve the detector, 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 surface radio antennas will improve the measurement accuracy and the field-of-view for the detection of cosmic rays. This in turn will lead to a better resolution of the energy and the depth of shower maximum (Xmax) in the second knee region of the cosmic-ray energy spectrum. Radio measurements combined with particle measurements will also enable a better estimation for the mass of the cosmic ray. In January 2020, a prototype station comprising three antennas and eight scintillators was deployed at the South Pole. In this talk, I will focus on the functioning of the radio hardware of this station: the mechanical installation, the electronic chain and its calibration. I will also give a small overview about the performance of the improved final hardware for the planned full-scale deployment.
