Sensor development and calibration for acoustic neutrino detection in ice
Abstract. A promising approach to measure the expected low flux of cosmic neutrinos at the highest energies (E> 1 EeV) is acoustic detection. There are different in-situ test installations worldwide in water and ice to measure the acoustic properties of the medium with regard to the feasibility o...
