Energy Reconstruction using a Template Method for Radio Signal of Air Showers recorded by the Prototype Station of the IceCube Surface 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 leading to a reduction of its sensitivity and resolution. In order to improve the detector, an enhancement of IceTop is planned in the coming years which consists of an array of scintillation panels and radio antennas. The radio antennas will lead to a better resolution of the energy and the depth of shower maximum (Xmax) around the second knee region of the cosmic-ray energy spectrum. Eventually, hybrid detection will enable a better estimation for the mass of the primary cosmic ray.
In January 2020, a prototype station comprising three antennas and eight scintillation panels was deployed at the South Pole. We developed the tools necessary to use a template-matching method for energy reconstruction and applied it to some of the radio events recorded. This template method uses Monte-Carlo simulations and compares it to recorded data. For this, a set of simulations is created using the reconstruction by IceTop as input to CORSIKA/CoREAS. In this talk, we will present the method and the preliminary results.
