The Acoustic Module for the IceCube Upgrade — •Christoph Günther, Jürgen Borowka, Dirk Heinen, Andreas Nöll, Maximilian Scharf, Lars Steffen Weinstock, Christopher Wiebusch, and Simon Zierke for the IceCube collaboration — RWTH Aachen University - Physics Institute III B, Aachen, Germany

One major goal of the IceCube Upgrade is improved calibration by deploying additional calibration devices in the center of IceCube. Amongst these devices are ten stand-alone Acoustic Modules, capable of receiving and sending acoustic signals. By trilateration, these will provide a position calibration of the sensor strings with a resolution of about 10 cm. Additionally, glaciological measurements of the acoustic ice properties are planned. In view of the future IceCube-Gen2 detector, this system will provide an important proof of principle for the reliable position determination on distance scales of a few hundred meters. The design of the modules and the status of the development are presented in this talk.
