Singao: A very large telescope for neutrino gamma astronomy and cosmic rays studies

We discuss the feasibility of a telescope consisting in a sampling array for extensive air showers measure combined with a muon tracking device. The sampling array will extend over a surface of ≥107 m2 while the muon tracking device will cover ≥104 m2. The telescope should be done with resistive plates counters and would become a very powerful device to study high-energy neutrinos and gamma-ray astronomy as well as cosmicray physics up to the highest energy (≥1019 eV) region.
