Description
The acoustic neutrino detection technique is a promising approach for future large-scale detectors with the aim of measuring the small expected flux of ultra-high energy cosmogenic neutrinos. This talk will focus on the application of the technique in water, based on site studies performed with different acoustic test arrays. Though the technique is intriguingly simple, challenges arise from e.g. anisotropic sound propagation, ambient noise or transient background in a natural environment. We will discuss those challenges and the strategies to face them, as well as developments in the simulation of the acoustic signal and hardware developments for sensors and calibration sources. Furthermore, current physics results towards the acoustic detection of ultra-high energy neutrinos in water will be presented. The acoustic detection technique will be investigated further in the next generation of Cherenkov neutrino telescopes that is currently prepared. We will discuss the technical implementation into those large optical detectors that is based on the experience gained with the acoustic test arrays.
