SNO detector underground  schematic

The Sudbury Neutrino Observatory (SNO), shown in the artist's conception above, was built 6,800 feet underground in a working nickel mine in Ontario, Canada. The detector is immersed in light (normal) water within a 10-story-high barrel-shaped rock cavity. Located in the deepest part of the mine, the overburden of rock shields the detector from cosmic rays. .
