Аннотация:The deployment of Tunka-133 EAS
Cherenkov light array with 1 km2 effective area
will be completed this autumn. The installation of
scintillation counters at the same array can provide
EAS muon and electron numbers measurement. Simultaneous
measurements of EAS energy, depth of
maximum, muon and electron numbers can provide
better resolution of primary mass in multi-parameter
distribution. This is essential for the detailed study of
the possible transition from galactic to extragalactic
cosmic rays at energies 1017 – 1018 eV. Our preliminary
simulation has shown that a network of about
20 muon detectors each of 10 m2 area and distance
between detectors (150 m) provides good enough
muon number measurement (Nμ/Nμ 10%).
