Abstract content

The Tunka Advanced Instrument for cosmic ray and Gamma ray Astrophysics, TAIGA, aims at accessing the gamma-ray sky in the multi-TeV to PeV energy regime. This energy range is key to spectroscopically resolving the cutoff regime of the - yet to be identified - Galactic cosmic ray Pevatrons. Sensitive gamma-ray observations in this energy range are essential for this task, and require a very large instrumented area (several square kilometers). TAIGA (Tunka Advanced Instrument for cosmic ray physics and Gamma ray Astronomy) experiment covers this energy range using a combination of different complementing detection techniques: Widely spaced large-angle imaging air Cherenkov telescopes (IACTs), a Cherenkov light shower front sampling timing array, and muon particle detectors. IACT images are combined with time- and amplitude-information from the timing array using a novel hybrid reconstruction method. This approach allows to maximize the effective area and to reach at the same time a good gamma-hadron separation also at low energies (few TeV). The muon detectors improve the gamma-hadron separation at higher energies. Here, the TAIGA design, the hybrid reconstruction principles, and the status of TAIGA will be presented.
