چکیده
|
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.
