Search for Extremely High Energy Neutrinos with AMANDA-II

AMANDA-II is a large volume neutrino telescope, designed to measure the energetic neutrino flux from astrophysical sources. A search for neutrinos exceeding 1 PeV has been performed using data collected by AMANDA-II in 2000. At these energies, the Earth is opaque to neutrinos. This, combined with the limited overburden above the detector, concentrates the expected signal at the horizon. A method of separatingsignal from the background of high energy downward going air showers has been developed and the results are discussed.
