Latest results from SNO and SNOLAB

The Department of Physics and Astronomy Colloquium: Dr. Art B. McDonald; Gordon and Patricia Gray Chair in Particle Astrophysics, Director SNO Institute; and, Physics Department, Queen's University, Kingston, Ontario to speak on “Latest results from SNO and SNOLAB.”

Abstract:
The Sudbury Neutrino Observatory (SNO) is a 1,000 tonne heavy-water-based neutrino detector in an ultra-clean environment created 2 km underground in a mine near Sudbury, Canada. SNO has used neutrinos from 8B decay in the Sun to observe one neutrino reaction sensitive only to solar electron neutrinos and others sensitive to all active neutrino flavors and has found clear evidence for neutrino flavor change. The SNO detector completed its operation at the end of 2006. Since the colloquium presented last January, data analysis has been completed for the final phase with an independent array of neutron detectors and new, more accurate results will be presented. The expansion of the underground facility to create a long-term international laboratory (SNOLAB) with a broad future experimental capability for the detection of dark matter, double beta decay, lower energy solar neutrinos and geo-neutrinos will also be described, along with a discussion of the status of experiments already in progress there.
