Abstract
The TREK large-scale coordinate tracking detector is being created at MEPhI on the basis of drift chambers for detecting the near-horizontal flux of muon bundles generated by ultrahigh-energy primary cosmic rays. The detector’s operation is modeled comprehensively in three stages to interpret experimental data: modeling an EAS in the CORSIKA environment, calculating interaction between EAS particles and the detector and its supporting structures in the Geant4 environment; and modeling of responses from drift chambers and on-chamber electronics in the Garfield ++ environment. Each stage of modeling is described, along with the exchange of data between them and the initial results.
