Sudbury Neutrino Observatory. A heavy-water Cherenkov detector located 2 km below the surface in a nickel mine in Ontario. SNO has given compelling evidence for oscillation of electron neutrinos to other flavors, providing the explanation for the solar neutrino problem. www.sno.phy.queensu.ca
This experiment, located 2 km beneath the surface in an active nickel mine in Sudbury, Ontario, is currently searching for neutrino oscillations in an attempt to disentangle the Solar Neutrino Problem. For more information, see: http://www.sno.phy.queensu.ca/.
