Description
With PeV astro-neutrinos observed by IceCube, the natural thought is: what if one had better sensitivity and better pointing accuracy? That would be the genuine start of high energy neutrino astronomy. The Earth-skimming nu_tau method meets this purpose. Starting at PeV energy and higher, the nu_tau is unique in that a mountain becomes a nu_tau to tau conversion target, and a subsequent valley becomes the shower volume for tau decay. The technique has been applied for the first time by Ashra-1. A new proposal, the Neutrino Telescope Array (NTA), would consist of the three sites of Mauna Loa, Mauna Kea and Mt. Hualalai, on the Hawaii Big Island, with detector design scaled from Ashra-1. Combining Cherenkov detection and the fluorescence ability of a central site, the NTA would be able to collect PeV nu_tau point sources within two billion light years, and would provide independent confirmation of IceCube PeV neutrinos. International collaboration issues would be touched upon.
