An IceCube Surface Array Enhancement station for deployment at Telescope Array — •Noah Goehlke for the IceCube collaboration — Institut für Astroteilchenphysik, Karlsruher Institut für Technologie (KIT), Karlsruhe

The IceTop array, located on the surface of the IceCube Neutrino Observatory, will be enhanced with hybrid radio and scintillator stations. The DAQ of each station is housed in a FieldHub. In January 2020 a full prototype station was deployed and is successfully operating and taking data. For the planned IceCube-Gen2 facility, the DAQ of the surface array and the in-ice array will be combined, using a modified FieldHub. The development of this FieldHub will be performed by the University of Utah, which is also contributing to the Telescope Array (TA), an air-shower detector array located in Utah.

By deploying a prototype station at TA, the Univerity of Utah is provided with the preliminary hardware of the future surface array, which is needed to design the new FieldHub. In addition, it can serve as a testing platform for IceCube-Gen2 and it enables cross calibration with TA. Since the environment and infrastructure in Utah and the South Pole differ significantly, adjustments of the prototype station are in development. As example, the detectors have to be able to measure air-shower particles at much higher ambient temperature and humidity levels as found at the South Pole.

In this contribution the adapted design of the prototype station as well as experiments done to investigate the detectors behavior at higher temperatures will be presented.
