Performance of the VERITAS experiment

Understand

VERITAS is a ground-based gamma-ray instrument operating at the Fred Lawrence Whipple Observatory in southern Arizona.

• With an array of four imaging atmospheric Cherenkov telescopes (IACTs), VERITAS is designed to measure gamma rays with energies from $\sim$ 85 GeV up to > 30 TeV.
• It has a sensitivity to detect a point source with a flux of 1$\%$ of the Crab Nebula flux within 25 hours.
• Since its first light observation in 2007, VERITAS has continued its successful mission for over seven years with two major upgrades: the relocation of telescope 1 in 2009 and a camera upgrade in 2012.
