Radio-Wave Propagation in Salt Domes: Implications for a UHE Cosmic Neutrino Detector

Alina-Mihaela Badescu (University Politehnica of Bucharest, Boulevard Iuliu-Maniu, No. 1-3, Bucharest, Romania) ; Alexandra Saftoiu (IFIN-Horia Hulubei, Strada Reactorului No. 30, P.O. Box MG-6, Bucharest-Magurele, Romania)

Salt deposits can be used as a natural dielectric medium for a UHE cosmic neutrino radio detector. Such a detector relies on the capability of reconstructing the initial characteristics of the cosmic neutrino from the measured radio electrical field produced at neutrino’s interaction in salt by the subsequent particle shower. A rigorous characterization of the propagation medium becomes compulsory. It is shown here that the amplitude of the electric field vector is attenuated by almost 90% after 100 m of propagation in a typical salt rock volume. The heterogeneities in salt also determine the minimal uncertainty (estimated at 19%) and the resolution of the detector.
