MAGIC
MAGIC, the Major Atmospheric Gamma Imaging Cherenkov telescope, is a high altitude (2200 m a.s.l.) system of two Imaging Atmospheric Cherenkov Telescopes (IACT). It is located at the Roque de los Muchachos Observatory on the Spanish island of La Palma in the Canary Islands. MAGIC is sensitive to Cherenkov radiation emitted in the Earth's atmosphere and detects air showers created by incident gamma rays. Each telescope has a mirrored surface of 17 m in diameter, which reflect and focus photons from the air shower onto imaging cameras, each with 1039 photomultiplier tubes.
