DESCRIPTION:Speakers: Dmitry Chernov (Moscow State University\, Skobeltsyn
  Institute of Nuclear Physics)\nThe main aim of the Sphere-Antarctic proje
 ct is connected to the fundamental problems of the cosmic ray (CR) physics
  and general astrophysics — the determination of the energy and mass com
 position of cosmic ray particles of ultra high and extremely high energies
  $10^{18}-10^{20}$eV. In the energy region above $6\\cdot10^{19}$eV modern
  experiments (Telescope Array and Pierre Auger Observatory) observed aniso
 tropy and the clustering of arrival directions of cosmic rays in some area
 s. The scientific importance of this problem stems from the lack of genera
 lly accepted acceleration mechanism of the CR particles above $3\\cdot10^{
 18}$eV\, the unknown nature of the sources of such particles\, the inconsi
 stencies of the results of major experiments in the part of the mass of CR
  composition and the discrepancy of experimental and model data. Scientifi
 c novelty f this project is in the methodology registration of the extensi
 ve air showers over a large area $\\sim$600 km$^2$ from altitude 30 km\, t
 hat allows to measure the two optical components of the shower Vavilov-Che
 renkov radiation and fluorescence light by the same SiPM sensitive element
 s of the detector simultaneously.\n\nhttps://indico.particle.mephi.ru/even
