A Deeper Understanding of the Universe from 2 km Underground
By creating an ultra-clean underground location with a highly reduced radioactive background, sensitive measurements can be performed to study fundamental physics, astrophysics and cosmology with neutrinos from the Sun, Dark Matter particles left over from the Big Bang and rare forms of radioactivity. The Sudbury Neutrino Observatory (SNO) is a neutrino detector containing 1,000 tonnes of heavy water and situated 2,000 meters underground in INCO's Creighton Mine near Sudbury, Ontario. SNO has observed neutrinos from the core of Sun and has found clear evidence for neutrino flavor change. This requires extensions to the Standard Model for elementary particles and confirms solar model calculations with great accuracy. The underground facility has been expanded to create a long-term international facility for underground science (SNOLAB), where measurements of Dark Matter, Double Beta Decay and Solar Neutrinos are progressing with the lowest radioactive background available anywhere. The latest results for SNO and the future scientific program for the SNO detector and SNOLAB will be discussed.
