Horizon-T is an innovative detector system constructed to study Extensive Air Showers (EAS) in the
energy range above 1016 eV coming from a wide range of zenith angles (0o - 85o). The system is located at the
Tien Shan High-altitude Science Station of the Lebedev Physical Institute of the Russian Academy of Sciences
at 3340 meters above sea level. It consists of eight charged particle detection points separated by distances
up to one kilometer as well as an optical detector subsystem to measure the Vavilov-Cherenkov light from the
EAS.
The time resolution of charged particles and Vavilov-Cherenkov light photons passage of the detector system is a
few ns. This level of resolution allows conducting a research of the atmospheric development of individual EAS.
This report focuses on a general description of the detector system and the individual sub-systems providing an
overview of the operations and latest results.
