TL;DR: In this article, the authors describe a concept for an instrument to measure the thickness of the ice shell on a planetary body such as Jupiter's moon Europa, which would be a passive receiver of a naturally occurring signal generated by interactions of deep penetrating cosmic ray neutrinos.

TL;DR: The NuPhase detector as mentioned in this paper was installed at an Askaryan Radio Array (ARA) station during the 2017/18 Austral summer season and achieved a trigger threshold of 1.6 for neutrino interactions that are in the far field of the array.
