Description
The origin of cosmic rays in PeV energy regime is currently among the hot unsolved problems both in the observational and theoretical aspects. For the sub -PeV gamma-ray astronomy, a project of the TAIGA-100 installation with an area of 100 km2 and an energy threshold of 300-400 TeV is being developed. The installation of such a site will allow for the study of galactic PeVatrons at a currently inaccessible sensitivity level.
The basic detectors of the new installation will be wide-angle Cherenkov stations with a viewing angle of ~ 1 ster and water Chrernkov muon detectors with an area of ~40 m2, similar to the muon detectors of the LHAASO installation. To study ultrahigh-energy cosmic rays, the installation will include scintillation detectors, 1-2 fluorescent telescopes, and radio antennas. This configuration of the detectors will make it possible to study in detail the mass composition of cosmic rays up to an energy of 1019 eV.
Over the next 5 years, it is planned to create an engineering array, with an area of ~ 0.5 km2 to demonstrate the effectiveness of the future installation for solving the problems of ultrahigh-energy gamma-ray astronomy and cosmic ray physics.
The report discusses the main detectors of the installation, the scientific program, plans to construction an engineering array and a possible location for the installation.
