1st CAP-TRIUMF Medal Goes to David Sinclair

14 April 2011

The Canadian Association of Physicists (CAP) and TRIUMF are pleased to announce that the 2011 CAP-TRIUMF Vogt Medal for Contributions to Subatomic Physics is awarded to Professor David Sinclair, a professor of physics at Carleton University and senior scientist at TRIUMF, for his exceptional vision and contributions to the study of neutrino physics in the pioneering SNO experiment, and for exemplary leadership in establishing the SNOLab facility.

Upon receiving the good news, Sinclair said, "I am extremely honoured to be selected to receive this award. Canada has such a strong program in sub-atomic physics encompassing the whole spectrum." Dr. Sinclair has been one of the leaders of the Sudbury Neutrino Observatory (SNO) and it is for his seminal contributions to the design, construction, and operation of SNO that he is awarded the CAP-TRIUMF Vogt Medal.

David Sinclair is one of Canada's most eminent scientists in the field of experimental subatomic physics. He has dedicated much of his research career to solving the "solar neutrino problem," an apparent deficit in the flux from the sun of difficult-to-detect neutrinos that are an essential end product of the fusion reactions in the solar core. To this end, Dr. Sinclair was one of the founders of the Sudbury Neutrino Observatory, the experiment that solved this puzzle. The resolution resulted in a significant revision of our understanding of elementary particles with the confirmation that not only do neutrinos have mass but they also change flavor and constitute an important fraction of all matter in the universe.  The journal Science cited the SNO results as one of the top 10 breakthro
