Construction and commissioning of new IACT telescopes for IceAct/IceCube — •Yuriy Popovych1, Jan Audehm2, Thomas Bretz2, Giang Do2, Adrianna García2, Florian Rehbein2, Merlin Schaufel1, and Christopher Wiebusch1 for the IceCube collaboration — 1III.

The IceAct Imaging Air Cherenkov Telescopes (IACTs) are used to observe cosmic-ray air-showers and work hereby as a veto detector for the IceCube Neutrino Observatory. The hybrid observation with IceCube allows cross-calibrating the energy-threshold and energy-scale of the surface detector IceTop as well as the directional reconstruction of the in-ice detector. In January 2019, two telescopes were installed at the South Pole and successfully integrated into IceCube data-taking. As an upgrade for these existing telescopes, new telescopes will be produced. To ensure high instrument reliability, each of the telescopes has to be tested individually simulating the harsh conditions at the South Pole. This talk will report on the status and testing results of the production of the new telescopes.
