IceScint: A surface scintillation detector array as Enhancement of IceCube — •Thomas Huber for the IceCube-Gen2 collaboration — Institut für Kernphysik (IKP), Karlsruher Institut für Technologie (KIT) and Deutsches Elektronen-Synchrotron, (DESY)

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

An Enhancement of the present surface array at IceCube (IceTop) by scintillation detectors is foreseen. A scintillator array can be used to increase the veto capabilities for cosmogenic neutrinos and enables an improvement in cosmic-ray reconstruction. This Enhancement and its research and development is in progress for a large-scale surface array of IceCube-Gen2.

2 Prototype stations with 7 scintillators showcasing technological advances for the next generation in cosmic ray detection have been developed for deployment at the South Pole in January 2018. For the readout of the scintillators, SiPMs (Sillicon Photomultiplier) are in use. These solid-state photosensors are similar in detection efficiency compared to classical photomultiplier tubes and have considerable advantages.

The detector design, the operation status and first measurements will be presented in this talk.
