Recent Results From The Sudbury Neutrino Observatory *

 

The Sudbury Neutrino Observatory (SNO) is a 1000 tonne heavy water Čerenkov detector located 2km underground in INCO Ltd's Creighton Mine, near Sudbury, Ontario. The experiment has been taking neutrino data since 1999. Previous SNO results on 8B solar neutrinos have revolutionized our understanding of neutrino flavour change and solved the Solar Neutrino Problem.  Since early 2005, SNO has been in its final phase of data taking which finishes at the end of 2006.  During this final phase, SNO's sensitivity to all active neutrino flavours is enhanced by the Neutral Current Detection (NCD) array. The NCD array consists of 40 3He and 4He proportional counters. The NCD array complements the photomultiplier tube array that has been acquiring data since the beginning of the experiment. The most recent solar and non-solar neutrino physics results from SNO will be presented. An update on the status of the experiment will also be given. The remainder of the talk will be an overview of the physics topics that SNO will address in the future.
