VERITAS (Very Energetic Radiation Imaging Telescope Array System) is a new major ground-based gamma-ray observatory with an array of four 12m optical reflectors for gamma-ray astronomy in the GeV - TeV energy range . The telescope design is based on the design of the existing 10m gamma-ray telescope of the Fred Lawrence Whipple Observatory. It consists of an array of imaging telescopes deployed such that they permit the maximum versatility and give the highest sensitivity in the 50 GeV - 50 TeV band (with maximum sensitivity from 100 GeV to 10 TeV). This VHE observatory will effectively complement GLAST.
The VERITAS Collaboration is composed of several member institutions and other collaborating members.
VERITAS is supported by the United States Department of Energy, the National Science Foundation, the Smithsonian Institution, the Natural Sciences and Engineering Research Council in Canada, Science Foundation Ireland and the Particle Physics and Astronomy Research Council in the U.K.
