Comparison and optimization of scintillation detector DAQ systems for the large surface array of IceCube-Gen2 — •Marie Oehler1, Andreas Haungs1, Bernd Hoffmann1, Thomas Huber1,2, Timo Karg2, Matt Kauer3, Marko Kossatz2, Max Renschler1, Harald Schieler1, Karl-Heinz Sulanke2, Delia Tosi3, Andreas Weindl1, and Chris Wendt3 for the IceCube collaboration — 1KIT, Karlsruhe, Germany — 2DESY, Zeuthen, Germany — 3UW, Madison, USA

The IceCube Observatory is a cubic-kilometer neutrino detector installed in the ice at the geographic South Pole. To increase the amount of detected extragalactic neutrinos the upgrade IceCube-Gen2 is under development. Among others, a large surface scintillation detector array is proposed.

Two prototype stations, consisting of seven detectors each, have been installed in the Antarctic Season 2017/2018. These detectors use scintillators, wavelength shifting optical fibers and silicon photomultipliers (SiPM). The stations use different data acquisition (DAQ) systems: The μDAQ system researched, developed and built by UW-Madison and the TAXI system researched, developed and built by KIT and DESY. μDAQ transfers the digitized integrated signals only to minimize the amount of transmitted data. TAXI can transmit the waveforms of the signals additionally and build local triggers for further detectors like radio antennas. In this contribution these two DAQ systems will be compared and an optimized setting for the DAQ system will be presented.
