Cherenkov Array at Themis

The Cherenkov Array at Themis refers to a telescope array designed for observing cosmic rays and high-energy gamma rays through the detection of Cherenkov radiation. Themis is a specific experimental site, often associated with the study of astrophysical phenomena. Cherenkov radiation is emitted when charged particles, such as electrons, travel through a dielectric medium (like air or water) at speeds greater than the speed of light in that medium.
