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

The IceCube Neutrino Observatory detects high-energy neutrinos from astrophysical sources. One factor limiting the angular resolution is the imprecise knowledge of the detector geometry. A planned extension of the detector, called the IceCube Upgrade, will address this issue. It consists of over 700 additional modules, comprising optical modules and calibration devices, in the central region. These calibration devices include ten Acoustic Modules, each capable of sending and receiving acoustic signals. Their deployment enables the calibration of the detector geometry via multilateration of transit times of these signals. We present the tests to characterize the Acoustic Modules, performed in the laboratory, a swimming pool, and a lake.
