The Acoustic Calibration Modules of the IceCube Upgrade — •Max Scharf, Dirk Heinen, Moritz Kellermann, Martin Rongen, Shefali Shefali, Lars Steffen Weinstock, Christopher Wiebusch, and Simon Zierke for the IceCube collaboration — III. Physikalisches Institut B, RWTH Aachen University

The IceCube Upgrade will expand the current IceCube Neutrino Observatory with seven additional strings of instrumentation. These will include an acoustic calibration system. This calibration system consists of ten acoustic modules, which are distributed along the new strings and can receive and emit acoustic signals over distances of up to several hundred meters. Using acoustic trilateration these modules are able to determine their positions and improve the overall quality of positioning in IceCube. Furthermore, the system will allow for glaciological measurements and will be an important demonstration of acoustic geometry calibration for the future IceCube Gen2 detector. Within the EnEx-RANGE project autonomous melting probes with acoustic instrumentation for positioning have been developed and successfully demonstrated. Based on this experience, acoustic modules are currently being developed and planned to be ready for production by late 2020. This talk will present the current status of the hardware development and results from test measurements.
