Calculations of the sensitivity of the particle detectors of ASEC and SEVAN networks to galactic and solar cosmic rays

Primary cosmic rays interact with the Earth’s atmosphere producing atmospheric showers, thus giving rise to the fluxes of secondary particles. Particle detectors of the Aragats Space Environmental Center (ASEC) and Space Environmental Viewing and Analysis Network (SEVAN) continuously measure neutral and charged fluxes of elementary particles, incident on the Earth’s surface. Using CORSIKA code, we have calculated response of ASEC detectors to galactic and solar cosmic rays. The main result of this paper is the estimation of the most probable energy of primary proton generating different secondary fluxes detected on the Earth’s surface by a variety of instruments. Results of the paper are applicable to recover the solar proton flux from the surface observations of the ground level enhancements (GLE). In addition, the determination of the most probable energies of the primary proton will help to study energy dependence of solar transient events (Forbush decreases, geomagnetic storms).
