Evidence for Neutrino Oscillations from the Sudbury Neutrino Observatory

The Sudbury Neutrino Observatory (SNO) is a large volume heavy water Cerenkov detector located 6800 feet udnerground in a mine near Sudbury, Ontario. Designed to address the problem of the missing solar neutrinos, this detector is unique due to its ability to simultaneously detect electron-type neutrinos through a charged-current interaction and all active neutrinos through a neutral-current interaction. In Phase II of the experiment, 2 tonnes of salt were added into the heavy water to enhance the detection of the neutral-current signal. This talk will focus on the latest results obtained for the flux of solar neutrinos (reported in nucl-ex/0309004). It will also briefly describe the recent upgrade to the detector for Phase III.
