The atmospheric Cherenkov telescope MAGIC for ground-based gamma-ray astronomy is operating since late 2003 on the Canarian island La Palma. The telescope’s 17 m diameter mirror is composed of 964 light weight, square all- aluminum mirrors of 234 m2 total area, which allows to lower the energy thresh- old to a value far beyond that of past generation of telescopes. The trigger sys- tem, based on ultra-fast decision logics (topological, time-coincidences, etc.) is designed to cope with very fast PMT signals (2 ns). Details of the MAGIC telescope will be presented, technical problems and solutions will be discussed as well as a report on three years of operations will be given.

Abstract
The atmospheric Cherenkov telescope MAGIC for ground-based gamma-ray astronomy is operating since late 2003 on the Canarian island La Palma. The telescope’s 17 m diameter mirror is composed of 964 light weight, square all- aluminum mirrors of 234 m2 total area, which allows to lower the energy thresh- old to a value far beyond that of past generation of telescopes. The trigger sys- tem, based on ultra-fast decision logics (topological, time-coincidences, etc.) is designed to cope with very fast PMT signals (2 ns). Details of the MAGIC telescope will be presented, technical problems and solutions will be discussed as well as a report on three years of operations will be given.
