| Resumo | |
The IceCube Neutrino observatory has discovered an astrophysical neutrino flux in the energy range >1 TeV with their highest energy event similar to 3 PeV. Although IceCube has excellent muon flavor identification, their ability to identify tau neutrinos is highly limited. We present a concept for observing the tau neutrino flux in the 1-100 PeV range, where a flux is guaranteed and its observation would give further support to the astrophysical origin of the IceCube flux. The design of the observatory requires an acceptance < A Omega > >400 m(2) srx (E/PeV)(1.5) to match the similar to 1 PeV IceCube all-flavor event rate in tau neutrinos provided a nu(e) : nu(mu) : nu(tau) = 1 : 1 : 1 flavor ratio. The energy dependence of the acceptance is designed to match the IceCube best-fit spectral flux index of E-2.5 so the spectrum is evenly sampled in the 1-100 PeV range. We present a backgroundfree implementation with pointing resolution < 1 degrees to begin the era of high energy tau neutrino astronomy. (AU) | |
