The Tunka-HiSCORE 9-station array: the array timing system and first array data analysis — •Andrea Porelli for the Tunka-HiSCORE collaboration — andrea.porelli@desy.de

HiSCORE is a concept of a non-imaging wide-angle EAS Cherenkov array designed to search for gamma ray sources above 10 TeV and to investigate spectrum and composition of cosmic rays above 100TeV. An engineering array with nine stations was deployed in October 2013 on site of the Tunka experiment in Russia. For precision angular reconstruction of showers, time-synchronization at the nsec-level is needed. We describe design and performance of the array DAQ, including the timing system based on the WhiteRabbit technology. Results from the prototype array will be compared to MC simulation.
