The Sudbury Neutrino Observatory (SNO) uses a Heavy Water detector to study solar
neutrinos. The results have solved the “Solar Neutrino Problem”, shown that neutrinos
have mass, and determined parameters in neutrino oscillations. This talk will give a brief
review of the development of the project and a discussion of the latest results (PRL 101 Sept.12 2008) and their significance. The heavy water in the SNO detector has now been returned and a new series of experiments are planned with the vessel filled with liquid scintillator. A new lab called SNOLAB has been constructed at the same depth. Some aspects of the experimental program for SNOLAB will be discussed.
