HAWC Highlights — •Armelle Jardin-Blicq for the HAWC collaboration — Max Planck Institut für Kernphysik

The High-Altitude Water Cherenkov (HAWC) Observatory was completed and began full operation on March 20, 2015. The detector consists of an array of 300 water tanks, each containing 200 tons of purified water and instrumented with 4 PMTs. Located at an elevation of 4100m a.s.l. near the Sierra Negra volcano in central Mexico, HAWC observes gamma rays in the 0.1-100 TeV range and has a sensitivity to TeV-scale gamma-ray sources an order of magnitude better than previous air-shower arrays. It has 2 sr field-of-view and >90% duty cycle make HAWC an ideal instrument for surveying the high-energy sky. We will describe the HAWC detector and its performance characteristics and report initial results from the first months of operation.
