The Acoustic Module for the IceCube Upgrade — Jürgen Borowka, •Christoph Günther, Dirk Heinen, Maverick Schönell, 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. Additionally, these signals are detected by compact acoustic sensors inside some of the optical sensor modules. The positions of emitters and receivers are determined by means of trilateration of the acoustic propagation times. With this system we aim for the calibration of the detector’s geometry with a precision better than a few 10 cm. In view of the future IceCube-Gen2 detector, this system will provide an important proof of principle for the reliable geometry calibration on distance scales of a few hundred meters. The design of the acoustic modules and the status of the development are presented in this talk.
