ИСТИНА

The new HiSCORE detector concept is based on Cerenkov air-shower detection, using the nonimaging technique. HiSCORE is build for gamma-ray astronomy from 10 TeV to several PeV, and cosmic rays studies from 100 TeV to 1 EeV. It will search for ”pevatrons” (ultra-high energy gamma-ray sources), and measure cosmic ray composition and spectrum in the transition range from a supposed Galactic to extragalactic origin of cosmic rays. The detector is made of wide-angle optical stations (0.6 sr) placed at distances of 150-200m, and will cover an area of 1 km2 - 100 km2, to be deployed in various stages. We report on status and plans of the Tunka-HiSCORE installation, in the Tunka valley near Lake Baikal, from first prototypes operating now to the > 1km2 arrays envisaged for the near future.
