Status of the Aachen Acoustic Laboratory (AAL) for acoustic neutrino detection — •Martin Bissok, Thorsten Glüsenkamp, Thomas Krings, Karim Laihem, Matthias Schunck, and Christopher Wiebusch — RWTH Aachen
Future neutrino telescopes with the aim to explore the extreme high energy region (E>1018 eV) require 1-2 orders of magnitude larger effective volumes compared to current optical detectors (IceCube 1 km3). One possible approach is the thermoacoustic detection of hadronic cascades from neutrino interactions in the South Pole ice. Main purpose of the Aachen Acoustic Laboratory (AAL) is to develop and establish appropriate detection methods under laboratory conditions. Central element is a large 3 m3 ice volume in which sensor and emitter elements are deployed. Thermoacoustic signals are generated by a pulsed laser beam injected into the ice. In this talk we present the status of the setup with emphasis on the measurement of laser induced thermoacoustic sound waves.
