Description
The TAIGA-experiment (Tunka Advanced Instrument for cosmic ray and Gamma ray Astrophysics) aims at gamma-astronomy in the multi-TeV to PeV energy range, using a new hybrid technology to build multi-km2 gamma telescopes at competitive cost.
TAIGA uses the synergy of two complementary air shower detection techniques: widely spaced imaging air Cherenkov telescopes (IACTs) and a Cherenkov light shower front sampling array. The first has good gamma-hadron separation, while the second yields precision reconstruction of shower energy, direction and impact point.
This allows for large distances between IACTs of up to 800-1000m, i.e. a cost-effective mono-mode IACT operation.
The proof of principle of this new concept is underway with the TAIGA prototype array, that will be commissioned in 2019 in the Tunka valley in Siberia: three IACTs of (10degx10deg), embedded in a 1km2 timing array with 120 detector stations.
We present results obtained with the current setup (0.5km2 timing array with first IACT).
