Tunka-HiSCORE – A new array for multi-TeV γ-ray astronomy and cosmic-ray physics

Abstract Tunka-HiSCORE (HiSCORE: Hundred Square-km Cosmic Origin Explorer) is a new Cherenkov EAS array for multi-TeV γ - ray astronomy and cosmic ray studies. The array will consist of wide-angle (0.6 sr) optical stations with 150 m distance between individual stations. The array will be constructed in several stages: beginning with a 1 km 2 array at the first stage up to 100 km 2 at the last stage. The first three stations have been installed during 2012 in Tunka Valley (50 km from the Southern tip of Lake Baikal) at the site of the Tunka-133 array. We describe the construction of the optical stations and the array DAQ, and present the first results of common operation of the new optical stations with the Tunka-133 array.
