Tunka-Grande & TAIGA-Muon

The Tunka-Grande scintillation array was put into service at the end of 2015. Its task is to study the energy spectrum and mass composition of cosmic rays in the energy range of 1016–1018 eV in combination with the Tunka-133 and Tunka-Rex facilities, and to search for diffuse gamma radiation in the energy range of 5×1016 – 5×1017 eV. The array of scintillation counters is combined in 19 stations on an area of 1 km2. Each of them consists of 2 parts: surface and underground


Surface part of Tunka-Grande station.

The TAIGA-Muon detectors complement the existing scintillation array with an estimated total detector area of about 2000 m2. It is worth noting that the operation of the new array in a wide range of zenith angles of arrival of primary particles will not only determine the flux of diffuse gamma rays, but also find local areas with an excess of them. Subsequently, upon detection, such areas will be studied in detail using the TAIGA-HiSCORE and TAIGA-IACT arrays.
