TAIGA Detector

TAIGA is complex, hybrid detector consisting of the following components:

  1. The HiSCORE wide Field of View (FoV; ~0.6 sr) integrating air Cherenkov detector stations, placed at distances of 150-200m from each other, covering an area of initially ~1 km² and ~100 km² at the later phase of the experiment. This detectors consists of 4 bialkali PMTs of size either 20 cm or 25 cm in diameter, set next to each other. The PMTs have Winston-cone shape light-guides, which increase their light collection area by factor of four. The PMT outputs are summed up.
  1. The Tunka-133 wide FoV integrating air Cherenkov detector. This full size detector, operational since 2009 with 185 stations, is spread over an area of ~3 km². The individual stations consist of single large PMT (diameter 20 cm or 37 cm).

  2. Up to 16 IACTs with reflector area of 10 m² and equipped with imaging cameras of 400 PMT-based pixels. The single pixels will have an aperture of 0.36°. FoV of the single telescope will be 8°x8°. The inter-telescope distances will be optimized in the range of 300-600 m.

  3. Tunka-Grande is a net of surface and underground stations for measuring the muon component of air showers. It is desirable to cover an area of a few 1000 m² area with underground muon detectors TAIGA-Muon for providing good rejection of hadron showers for energies ≥ 100 TeV. 

  4. For the time being TAIGA is hosting Tunka-Rex experiment for measuring the radio emission of air showers.
