VERITAS (Very Energetic Radiation Imaging Telescope Array System) is a major ground-based gamma-ray observatory with an array of four 12m optical reflectors for gamma-ray astronomy in the GeV - TeV energy range. Located at FLWO in Arizona, it consists of an array of imaging telescopes that permit the maximum versatility and give the highest sensitivity in the detection of light created by cosmic gamma rays striking the earth's atmosphere.
