Characterization and Optimization of the Readout Electronics for IceAct Telescopes — •Andreas Nöll1, Thomas Bretz2, Lars Heuermann1, Merlin Schaufel1, Lea Schlickmann1, and Christopher Wiebusch1 for the IceCube collaboration — 1III. Physikalisches Institut B, RWTH Aachen University — 2GSI Helmholtzzentrum für Schwerionenforschung
IceAct is an Imaging Air Cherenkov Telescope array located at the South Pole as part of the IceCube Neutrino Observatory. The telescopes feature a 61 pixel camera based on Silicon Photomultipliers (SiPM). The camera signals are processed and digitized by the TARGET module, developed for the Cherenkov Telescope Array (CTA). The inherent high rate of ambient photons caused e.g. by stars, the Moon, and auroras combined with the high decay time of the SiPM signal results in a signal pile-up. The TARGET system provides an analog front-end for pulse shaping combined with a high sampling rate of 1GSa/s to accommodate the pile-up. Extensive tests are necessary to understand the complete signal chain from the SiPM to digitization. In this talk a characterization of the current system is presented. In addition design improvements, based on electronics simulations and tests with prototypes, will be proposed.
