IceAct Upgrade Status - SiPM Based Compact Imaging Air-Cherenkov Telescopes for IceCube — •Hannah Erpenbeck, Thomas Bretz, Lars Heuermann, Cengiz Kuruoglu, Frank Malowski, Mark Meyers, Florian Rehbein, Merlin Schaufel, and Christopher Wiebusch for the IceCube collaboration — RWTH Aachen University - Physics Institute III B, Aachen, Germany

IceAct is an array of compact imaging air Cherenkov telescopes that are optimized for the harsh conditions of the South Pole. Since January 2019 two IceAct telescopes, featuring 61 SiPM pixels and a Fresnel lens based optics, operate at the surface above IceCube in the center of IceTop. By hybrid measurements of cosmic rays together with the IceTop and the IceCube detectors, they enable improved cosmic ray studies and cross calibrations. Six new telescopes are currently being assembled as an upgrade for IceAct. To ensure high instrument reliability, each of the telescopes is tested individually including field tests and strict quality assurance of all components. This talk will report on the project status as well as on the construction and the testing results of the new telescopes.
