Study of a Large Array to Detect Ultra-high Energy Tau Neutrino

The $PeV$ cosmogenic neutrino is still interesting argument. Since neutrinos interact weakly with matter, the detection of their direction will precisely point out source in space. In this paper, we show results simulation tau lepton air showers induced by high energy detected an array stations designed to use Earth Skimming method improved "mountain chain screen" strategy. Both track time stamp and position information on are used reconstruct shower estimate number events. studied consists 640 ($40 \times 16$) spread over area $0.6\,km^2$ starting from $1500\,m$ above sea level (a.s.l.) $30^{o}$ inclined plane mountain.
