Аннотация:The HiSCORE (Hundred*i Square-km Cosmic ORigin Explorer) detector aims at
the exploration of the accelerator sky, using indirect air-shower observations of cosmic rays from
100 TeV to 1 EeV and gamma rays in the last remaining observation window of gamma-ray
astronomy from 10 TeV to several PeV. The main questions addressed by HiSCORE are cosmic
ray composition and spectral measurements in the Galactic/extragalactic transition range, and
the origin of cosmic rays via the search for gamma rays from Galactic PeV accelerators, the
pevatrons. HiSCORE is based on non-imaging Cherenkov light-front sampling with sensitive
large-area detector modules of the order of 0.5m2. A prototype station was deployed on the
Tunka cosmic ray experiment site in Siberia, where an engineering array of up to 1km2 is planned
for deployment in 2012/2013. Here, we address the expected physics potential of HiSCORE,
the status of the project, and further plans.
