STUDY DATA FROM M. ZAZYAN AND CO-AUTHORS UPDATE KNOWLEDGE OF ASTROPHYSICS
Science Letter
January 12, 2010
According to a study from Yerevan, Armenia, "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. 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),"
wrote M. Zazyan and colleagues (see also Astrophysics).
The researchers concluded: "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)."
Zazyan and colleagues published the results of their research in
Astroparticle Physics (Calculations of the sensitivity of the particle
detectors of ASEC and SEVAN networks to galactic and solar cosmic
rays. Astroparticle Physics, 2009;32(3-4):185-192).
