MAGIC (Major Atmospheric Gamma Imaging Cherenkov Telescopes) is a system of two Imaging Atmospheric Cherenkov telescopes provided with mirrors of 17 m diameter. They are located at the Roque de los Muchachos Observatory on La Palma, one of the Canary Islands, at about 2200 m above sea level. MAGIC detects particle showers released by cosmic gamma rays with photon energies between 30 GeV and 100 TeV, both of galactic and extragalactic origin. The gamma rays interact with the athmosphere and produce cascades of charged particles, which emit Cherenkov radiation that the telescopes can detect. The MAGIC telescopes are currently operated by an international collaboration of approximately 165 astrophysicists from 24 institutions and consortia from 12 countries.
