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

The IceCube Neutrino Observatory at the South Pole detects high energy neutrinos from astrophysical sources. With the upcoming IceCube Upgrade, more than 700 detector modules along with calibration devices will be deployed at the central core of IceCube, 2 km deep into the Antarctic ice. Ten Acoustic Modules (AM) will transmit and receive acoustic signals from 5 to 40 kHz. By means of trilateration of the propagation times of these acoustic signals, we determine the positions of the AMs with an accuracy of about 10 cm and thus calibrate the geometry of the detector. The AM consists of acoustic transducer, communication and signal generation power electronics, and receiver electronics, all embedded in a housing, withstanding the pressure in the ice. For the proper measurement of transit times between different modules a dedicated synchronization and timing protocol has to be implemented. This talk presents an overview of the functionality and technical design of the main components and describes the development of appropriate firmware.
