Physics Division Seminars bring us speakers on a variety of physics related subjects. Usually these are held in the Building 6008 large Conference Room, at 3:00 pm on the chosen day, but times and locations may vary. For more information, contact our seminar chairman,

By creating a location that is essentially free from radioactive
background, sensitive measurements can be performed to test fundamental
laws of physics 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 modification of the Standard Model for elementary
particles and confirms solar model calculations with great accuracy. The
underground facility is now being expanded to create a long-term
international facility for underground science (SNOLAB), where
measurements of Dark Matter, Double Beta Decay and Solar Neutrinos will
be performed with the lowest radioactive background available anywhere.
The results for SNO and the future scientific program for SNO and SNOLAB
will be described.
