MAGIC (Major Atmospheric Gamma Imaging Cherenkov Telescopes) is a system of two Imaging Atmospheric Cherenkov telescopes situated 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 gamma rays, using the Cherenkov radiation, i.e., faint light radiated by the charged particles in the showers. With a diameter of 17 meters for the reflecting surface, it was the largest in the world before the construction of H.E.S.S. II. The first telescope was built in 2004 and operated for five years in standalone mode. A second MAGIC telescope (MAGIC-II), at a distance of 85 m from the first one, started taking data in July 2009. Together they integrate the MAGIC telescope stereoscopic system.〔"Technical status of the MAGIC telescopes", MAGIC collaboration, Proc. International Cosmic Rays Conference 2009, arXiv:0907.1211〕 MAGIC is sensitive to cosmic gamma rays with energies between 50 GeV (later lowered to 25 GeV) and 30 TeV due to its large mirror; other ground-based gamma-ray telescopes typically observe gamma energies above 200...300 GeV. Satellite-based detectors detect gamma-rays in the energy range from keV up to several GeV. ==Aims== The goals of the telescope are to detect and study primarily photons coming from: * Accretion of black holes in Active Galactic Nuclei * Supernova remnants, due to their interest as sources of cosmic rays. * Other galactic sources such as pulsar wind nebulae or X-ray binaries. * Unidentified EGRET or Fermi sources * Gamma ray bursts * Annihilation of Dark matter 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MAGIC (telescope)」の詳細全文を読む スポンサード リンク
