Location/Infrastructure | Scientific station of Irkutsk State University, Tunka Valley ( 50 km from the lake Baikal) |
Funding agencies | Russian Ministry of Education and Science, RFBR(Russia), DFG (Germany), INFN(Italy) |
Scientific goals | Origin of Galactic cosmic rays |
Design | 133 Cherenkov detectors on the base of 20cm diameter PMT combined in 19 clusters (7 PMT each) on the area 1 km2 , 4 water Auger like tanks, 19 scintillator detectors ( 1 m2 ) |
Present status (R&D, construction, data taking, closed) | Construction, data taking with old Tunka-25 array and 2 water ranks. |
Most relevant results | Energy spectrum and mass composition of cosmic rays from 5*1015 to 5*1016 eV |
Perspective: | 200 PMT, 2 water tanks, optical cable(12 km) and components for the firsts clusters. Predecessor was Tunka-25 array mo merging |
Which relevant results are expected, and when | Enegy spectrum with high resoulution up to 1018 eV. |
