VERITAS (Very Energetic Radiation Imaging Telescope Array System) is a major ground-based gamma-ray observatory located at the basecamp of the Fred Lawrence Whipple Observatory in southern Arizona. VERITAS comprises an array of four 12m optical reflectors for gamma-ray astronomy in the very high energy (VHE: 50 GeV - 50 TeV) range.
