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

  1. TAIGA-HiSCORE. An array of wide Field of View (FoV; ~0.6 sr) integrating air Cherenkov detector stations, placed at distances of 150-200m from each other. The prototype phase array has 120 stations and an area of ~1 km² (with a possible upgrade to 10…100 km² at a later project stage).
  1. Tunka-133. An array of wide FoV integrating air Cherenkov detectors. 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. TAIGA-IACT. An array of up to 16 Imaging Air Cherenkov Telescopes (IACTs) with a reflector area of 10 m² and equipped with imaging cameras of 560 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. TAIGA-Muon and Tunka-Grande. 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.
