MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov Telescope) is a Gamma ray telescope sited at Roque de los Muchachos Observatory on La Palma in the Canary Islands at about 2200 m above sea level. It detects the particle shower released by the cosmic gamma-rays, and also Cherenkov light.

It can detect cosmic gamma rays with energies between 30 GeV and 30 TeV; ground-based gamma ray telescopes are normally sensitive to energies above 300 GeV, while satellites detect on the order of keV up to GeV).

The goals of the telescope are to detect the following, among other things:

[edit] Specifications

The telescope has the following specifications:

  • A collecting area 239 m² consisting of 50 cm x 50 cm Aluminium reflectors
  • A lightweight carbon fibre frame
  • A detector consisting of 396 separate hexagonal photomultiplier detectors in the center (diameter: 2.54 cm) as well as 180 photomultiplier detection arrays around the edge (diameter: 3.81 cm).
  • Data is transferred by fibre optic cables
  • Signal digitalization is done via a analog-digital converter (frequency 300 MHz)
  • The weight of the whole telescope is 40,000 kg
  • A reaction time of about 20 seconds to point to any section of the sky
