The Gamma Ray Detection Sensitivity of the Upgraded VERITAS Observatory
Abstract
The VERITAS VHE gamma-ray observatory recently completed a major upgrade of its camera and pattern triggering systems. Bias curve testing of the upgraded VERITAS Observatory under dark sky conditions indicates a 50% increase in photon detection efficiency, and a 30% reduction in triggering threshold. Optimization of analysis of the Crab nebula observations performed in late 2012 and early 2013 is ongoing. A comparison of these results with pre-upgrade Crab observations can provide the most direct method for quantifying the impact of the upgrade on VERITAS sensitivity and energy threshold.
