IceAct, SiPM based Imaging Air Cherenkov Telescopes for IceCube — •Merlin Schaufel, Jan Auffenberg, Pascal Backes, Thomas Bretz, Giang Do, Erik Ganster, Jan Paul Koschinsky, Leif Rädel, Martin Rongen, Anna Sauret, Johannes Schumacher, Aatif Waza, and Christopher Wiebusch for the IceCube collaboration — III. Physikalisches Institut, RWTH Aachen University

The development of cost effective and compact Silicon Photomultipliers (SiPM) based Imaging Air Cherenkov Telescopes enables new measurements using a hybrid configuration with ground based detectors. IceAct is a proposed surface array of such telescopes above IceCube. During January 2018, a new version of an IceAct telescope demonstrator featuring 61 SiPM pixels and improved optics was installed in the center of the IceTop surface detector at the geographic South Pole. Combining information from the telescope and IceCube, it is possible to test the performance in primary particle discrimination, energy calibration and veto capabilities.

We present the status of the project and the prospects of the upcoming data taking season during the antarctic winter.
