COLLABORATION,
Carleton University
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.
