The Large High Altitude Air Shower Observatory (LHAASO, 拉索) is a gamma-ray and cosmic-ray observatory in Daocheng, in the Garzê Tibetan Autonomous Prefecture in Sichuan, China. It is designed to observe air showers triggered by gamma rays and cosmic rays. The observatory is at an altitude of 4,410 m
etres (14,470 ft) above sea level. Observations started in April 2019. The observatory covers an area of some 145 hectares (360 acres). It has three underground observing pools, each "more than triple the size of the Water Cube (National Aquatic Center) in Beijing". One of the pools is designed to contain 100,000 tonnes (98,000 long tons; 110,000 short tons) of water. The pools will contain 12 telescopes to capture high-energy photons. Cherenkov radiation detectors are used. Research teams from Australia and Thailand will participate in the project directly, with others expressing interest. The observatory works essentially as the CASA-MIA observatory did but with a bigger surface array, better muon detectors, improved designed layout and at higher altitude.
