Description

The Taiga experiment at Tunka valley near Baikal is heading with new scintillation detector stations named Taiga-Muon, for advanced study of astroparticle. The realistic model of experiment was created by using GEANT4 software package. The Monte Carlo simulation of experiment is done with Corsika and Geant4, with the help additional libraries FLUKA, COAST. The extensive air showers of primary gamma-quanta and protons with energies 100, 300, 1000, 3000 TeV and having theta angle 0, 30, 45 degrees are created with Corsika. Coast library is used to select the particle within the area of interest. The programming language C++ is mainly used to simulate the experiment, final data analysis is done using ROOT package. The trigger efficiency is calculated with simulated results. The trigger efficiency for both Tunka-Grande and Taiga-Muon were calculated. The Geant4 data is analyzed by changing the depth of soil to optimize its thickness. The suppression factor of electromagnetic showers from hadronic showers is studied. This study leads us to find the optimum depth of soil in the case of Taiga-Muon detector stations. Data on the detection efficiency for primary gamma-quanta and proton events are presented as well as suppression factor.
