Abstract :
Simulation of gamma and hadron showers in the energy range 100GeV- 25TeV has been carried out. For a big ideal Cherenkov light array, characteristics of lateral distribution of Cherenkov photon density have been studied. Results from this ideal detector are compared with those simulated for a real TUNKA- like array to investigate experimental potential of using existence of a hump in lateral distribution of Cherenkov photon density for gamma-hadron separation. It is shown that by using this technique the proton rejection efficiency of %63 can be achieved in typical TUNKA-like arrays.
