Design and Construction of the Acoustic Module for the IceCube Upgrade — •Andreas Nöll, Jan Audehm, Charlotte Benning, Jürgen Borowka, Pierre Dierichs, Mia Giang Do, Oliver Gries, Christoph Günther, Dirk Heinen, Adam Rifaie, Joëlle Savelberg, Christopher Wiebusch, and Simon Zierke for the IceCube collaboration — III. Physikalisches Institut B, RWTH Aachen University

The IceCube Neutrino Observatory is a cubic kilometer size detector located at the geographic South Pole, consisting of 5160 Digital Optical Modules (DOMs). In the Antarctic summer 2025/26 more than 700 new modules will be installed as part of the IceCube Upgrade. These include ten Acoustic Modules (AMs), capable of transmitting and receiving acoustic signals between 5 and 30kHz. Additionally, up to 30 acoustic receivers will be located in new DOMs. Goal of these devices is improving the geometry calibration based on multilateration of the measured acoustic propagation times. This talk presents the design and construction of AMs, including the acoustic transducer and its internal electronics.
