Performance Tests of the Acoustic Module for the IceCube Upgrade — •Charlotte Benning, Jan Audehm, Jürgen Borowka, 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 one cubic kilometer particle detector consisting of 5160 Digital Optical Modules located in the ice at the geographic South Pole. During the IceCube Upgrade more than 700 additional modules will be deployed at the center of the existing detector with the purpose of calibrating and enhancing the detectors capabilities. Part of this upgrade will be ten specialized Acoustic Modules which are capable of receiving and transmitting acoustic signals from 5 to 40 kHz. Based on the principle of trilateration, the positions of acoustic and optical modules will be determined from the propagation times of these signals. With this system we aim to achieve an accuracy of a few 10 cm for the geometrical precision of the detector. In this talk the results of performance tests of the acoustic modules in the laboratory and at a local swimming pool are presented.
