The MAGIC Cherenkov Telescope Array

The MAGIC Collaboration has built in 2001–2003 a first large atmospheric imaging Cherenkov telescope, MAGIC-I, with a mirror surface of 236 sq.m. and equipped with photo-multiplier tubes of optimal efficiency.

In 2009, a second telescope of essentially the same characteristics was added; MAGIC-II was installed at a distance of 85m from MAGIC-I.

With the accent of these instruments on large mirror surface and best light collection, cosmic gamma-rays at an energy threshold lower than any existing or planned terrestrial gamma-ray telescope have become accessible. So far achieved has been a threshold of 25 GeV.
