| Résumé : | IceAct is an array of compact Imaging Air Cherenkov Telescopes at the ice surface as part of theIceCube Neutrino Observatory. The telescopes, featuring a camera of 61 silicon photomultipliersand fresnel-lens-based optics, are optimized to be operated in harsh environmental conditions,such as at the South Pole. Since 2019, the first two telescopes have been operating in a stereoscopicconfiguration in the center of IceCube’s surface detector IceTop. With an energy threshold ofabout 10 TeV and a wide field-of-view, the IceAct telescopes show promising capabilities ofimproving current cosmic-ray composition studies: measuring the Cherenkov light emissionsin the atmosphere adds new information about the shower development not accessible with thecurrent detectors. First simulations indicate that the added information of a single telescope leads,e.g., to an improved discrimination between flux contributions from different primary particlespecies in the sensitive energy range. We review the performance and detector operations of thetelescopes during the past 3 years (2020-2022) and give an outlook on the future of IceAct. |
