IceScint: A surface scintillation detector array for IceCube-Gen2 — •Thomas Huber1,2, Aswathi Balagopal V2, Andreas Haungs2, Timo Karg1, Samridha Kunwar1, Agnieszka Leszczynska2, Harald Schieler2, and Andreas Weindl21Deutsches Elektronen-Synchrotron, (DESY) — 2Institut für Kernphysik (IKP), Karlsruher Institut für Technologie (KIT)

To increase the amount of detected high-energy neutrinos of cosmic origin IceCube-Gen2 is under development.

In addition to in-ice veto strategies, cosmic-ray showers can be directly vetoed on the ice surface. A surface veto detector built up by scintillators and extended to large areas of several tens of km2 can be used to detect cosmic-ray showers and veto the in-ice muons and neutrinos they produce.

For the readout of the scintillators SiPMs (Sillicon Photomultiplier) are foreseen. These solid-state sensors are similar in detection efficiency compared to classical photomultiplier tubes. Beside this, SiPMs have additional advantages like a more compact structure, a low bias voltage and provide a better performance at low temperatures like found at the South Pole.

The detector design and first prototype measurements will be presented in this talk.
