Status of the new TAIGA hybrid detector — •Andrea Porelli for the TAIGA collaboration — DESY, Zeuthe,Germany

The new TAIGA (Tunka Advanced Instrument for cosmic ray physics and Gamma Astronomy) hybrid detector aims to address gamma-ray astronomy at energies from a few TeV to several PeV, as well as cosmic ray physics above 100 TeV. By combining the wide angle (0.6sr) Cherenkov timing detector TAIGA-HiSCORE with the 4-m class Imaging Atmospheric Cherenkov Telescopes TAIGA-IACT (10x10 degrees FoV), it provides a cost effective-way to instrument large areas (>10km2). The EAS reconstruction provided by TAIGA-HiSCORE (energy, incoming direction and its core position) allows to increase the distance between the IACTs up to 1000-1200 m. In addition to the Cherenkov light detectors, we intend to deploy an array of muon detectors (TAIGA-Muon array) spread over an area of 1 km2 with a total area of about 2000 m2. The TAIGA-IACT, together with the TAIGA-Muon array, will be used for selection of gamma-ray induced EAS. At present, the TAIGA first stage has been constructed in Tunka valley, ∼50 km West from the Lake Baikal. The detector consists of 47 TAIGA-HiSCORE Cherenkov stations distributed over an area of 0.5 km2, and the first IACT of the TAIGA-IACT array. During 2018-2019 we intend to increase number of the TAIGA-HiSCORE stations up to 100-120, covering an area of 1 km2, and to deploy 1 - 2 additional TAIGA-IACTs. The first experimental results with the TAIGA first stage will be reported.
