Description
We describe a novel application of extreme high energy neutrino detection: a concept for an instrument to measure the thickness of the ice shell on a planetary body, such as Jupiter’s moon Europa, by making use of the Askaryan Effect RF signal from EHE neutrinos. Unlike the current most often considered approach to measuring outer planetary moon ice sheet thickness, a large high powered active ice-penetrating radar, such an instrument would be a passive receiver of the naturally occurring signal generated by interactions of deep penetrating EHE neutrinos. It is therefore potentially less massive and requires less power, making it very attractive for interplanetary missions. We discuss the basic concept and consider the instrument design requirements from the perspective of a NASA Outer Planet Orbiter Mission. We show results [1] of simulations, compare signal-to-noise estimates, and examine possible components and configurations for the antenna, receiver, and electronics. We note some options that can be used to reduce mass and power. Finally, we identify issues that would need further study to produce a more concrete design.
