Title: An ultra-high-energy-neutrino detector using rock salt and ice as detection media for radar method

Abstract

We had found radio-wave-reflection effect in rock salt for detection of an ultra-high energy neutrino (UHE{nu}) which is generated in GZK processes in the universe. When an UHE{nu} interacts with rock salt or ice as a detection medium, the energy converts to a thermal energy. Consequently, a temperature gives rise along an UHE{nu} shower at the interaction location. The permittivity arises with respect to the temperature at ionization processes of the UHE{nu} shower which is composed of hadronic and electromagnetic multiplication processes. The irregularity of the refractive index in the medium for radio wave rises to a reflection. The reflection effect with a long attenuation length of radio wave in rock salt and ice would yield a new method to detect UHE{nu}. They could be used for detection media in which the UHE{nu} interacts with. We could find a huge amount of rock salt or ice over 50 Gt in a natural rock salt formation or Antarctic ice sheet. Radio wave transmitted into the medium generated by a radar system could be reflected by the irregularity of the refractive index at the shower. Receiving the reflected radio wave yields information about the UHE{nu}.
