متن کاملAuger : a Large Air Shower Array and Neutrino Telescope
Detection of Ultra High Energy Neutrinos (UHEN), with energy above 0.1 EeV (10 18 eV) is one of the most exciting challenges of high energy astrophysics and particle physics. In this article we show that the Auger Observatory, built to study ultra high energy cosmic rays, is one of the most sensitive neutrino telescopes that will be available during the next decade. Furthermore, we point out th...

متن کاملGaw (gamma Air Watch): a Novel Imaging Cherenkov Telescope
GAW (Gamma Air Watch) is a new imaging Cherenkov telescope designed for observation of very high-energy gamma-ray sources. GAW will be equipped with a 3 meter diameter Fresnel lens as light collector and with an array of 300 multi-anode photomultipliers at the focal plane. The pixel size will be 4 arcmin wide for a total field of view of 10.5 degrees. Whith respect to the planned imaging Cheren...
