Description
The TAIGA (Tunka Advanced Instrument for cosmic ray physics and Gamma Astronomy) facility aims to study the very high energy gamma-rays at energies from a few TeV to several PeV, as well as cosmic rays from 100 TeV to several EeV. Combination of the wide-angle Cherenkov timing detector TAIGA-HiSCORE with the 4-m class Imaging Atmospheric Cherenkov Telescopes (TAIGA-IACT) of FoV of 9,6 degrees offers a cost-effective way to construct a large array for very high energy gamma astrophysics. At present the one square km installation TAIGA-1 is in operating in Tunka valley, ~50 km West from the southernmost tip of the lake Baikal. It consists of 120 TAIGA-HiSCORE wide-angle (0.6 ster) stations distributed over an area of.1,1 km^2, three 4-m class Imaging Atmospheric Cherenkov Telescopes (IACT) with FoV of 9.6 degrees and 250 m2 of particle detectors. The effective area of the system of 3 IACTs completely covers the area of TAIGA-HISCORE wide-angle installation of the TAIGA-1 complex for gamma-ray energy above 80 TeV. The next plans for the development of the TAIGA-1 installation include the deployment of 2 more IACTs. We expect a sensitivity of the TAIGA-IACT installation with 5 IACTs in the novel, hybrid stereo mode for detecting gamma-rays with energies greater than 10 TeV for 100 hours of observation of 10^{-12} TeV cm^{-2} s^{-1} and an angular resolution of 0.2 degrees. The future development plan of the TAIGA array up to 10 km² is presented.
