Аннотация:A central question of Astroparticle Physics, the origin of cosmic rays, still remains unsolved. HiSCORE (Hundred*i
Square-km Cosmic ORigin Explorer) is a concept for a large-area wide-angle non-imaging air shower detector, addressing
this question by searching for cosmic ray pevatrons in the energy range from 10 TeV to few PeV and cosmic rays in the
energy range above 100 TeV. In the framework of the Tunka-HiSCORE project, first prototypes have been deployed on the
site of the Tunka-133 experiment, where we plan to install an engineering array covering an area of the order of 1 km2
. On
the same site, also imaging and particle detectors are planned, potentially allowing a future hybrid detector system. Here
we present the HiSCORE detector principle, its potential for cosmic ray origin search and the status of ongoing activities
in the framework of the Tunka-HiSCORE experiment.
