TAIGA Detector


TAIGA detectors

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 stations are grouped into 4 clusters on an area of ~ 1 km² (with a possible upgrade to 10 km² at a later project stage).
  1. Tunka-133. An array of wide FoV integrating air Cherenkov detectors. This full-size detector has been in operation since 2009. Consisted of 133 detectors located on an area of ~ 3 km². Since 2012, the number of stations has increased to 175. Each station consists of single large PMTs (20 cm in diameter).

  2. TAIGA-IACT. An array of 3 Imaging Air Cherenkov Telescopes (IACTs) with a reflector area of 10 m² and equipped with imaging cameras ~ 600 PMT-based pixels. The single pixels have an aperture of 0.36°. FoV of the single telescope is 10°. The inter-telescope distances are optimized in the range of 300-500 m.

  3. TAIGA-Muon and Tunka-Grande. Tunka-Grande consists of 19 stations with the ground and underground counters for measuring the muon component of air showers. The TAIGA-Muon includes 3 stations with 8 ground-based scintillation counters for registration of all EAS charged particles at the installation level and 8 underground ones for registration of muon components.
