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 (0.6sr) optical stations with 150m distance between individual stations. The array will be constructed in several stages: beginning with a 1km2 array at the first stage up to 100km2 at the last stage. The first three stations have been installed during 2012 in Tunka Valley (50km 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.
