TAIGA-IACT is the net of imaging atmospheric Cherenkov telescopes distributed over the area of approx. 5 km2 of the Tunka site and aimed for detecting gamma-rays in combination with the HiSCORE instrument. This method of detecting is novel and consisting in combination of imaging and non-imaging techniques.


Prototype of TAIGA-IACT (under construction).


The telescope structure consisting in a segmented reflector and a photomultiplier-based camera installed on alt-azimuthal mount. The reflector has Davies-Cotton design with focal length of about 5m and comprises of 34 round shape segments with 600 mm diameter. The camera has 574 pixels each of which consisting photomultiplier equipped with hexagonal compound parabolic concentrator (Winston cone). Size of the pixel is 30 mm (flat-to-flat of hexagonal entrance pupil).
