Arthur B. McDonald

Arthur Bruce McDonald ( born August 29, 1943 in Sydney, Nova Scotia ) is a Canadian physicist and director of the Sudbury Neutrino Observatory Institute. He also holds the Gordon and Patricia Gray Chair in Particle Astrophysics at Queen 's University in Kingston, Ontario.

Training

McDonald received the B.Sc. in physics in 1964 and the M.Sc. in physics in 1965 from Dalhousie University in Nova Scotia. The Ph. D. in Physics, he received from the California Institute of Technology.

Academic career

McDonald worked from 1970 to 1982 as a scientist at the Chalk River Laboratories northwest of Ottawa. From 1982 to 1989 he was professor of physics at Princeton University, where he was a senior scientist at the Princeton cyclotron. He left Princeton in 1989 to become a professor at Queen 's University in Kingston ( Ontario). At the same time he became in 1989 director of the SNO. From 2002, he held at Queen 's University, the University Research Chair from 2006, the Gordon and Patricia Gray Chair in Particle Astrophysics.

He has been a visiting scientist at CERN (2004), Los Alamos National Laboratory (1981 ), Oxford, the University of Hawaii, the University of Washington in Seattle.

He is married and has four children.

Research and Honors

In August 2001, a research group discovered by McDonald, oscillate that neutrinos from the sun really in muon - neutrino () and tau neutrino or tauon (). This report was published in Physical Review Letters and widely regarded as significant. He is regarded as persuasive evidence of the explanation of the riddle of the solar neutrinos by neutrino oscillations (MSW effect).

McDonald and Yoji Totsuka were awarded in 2007, the Benjamin Franklin Medal in Physics. McDonald is a Fellow of the Royal Society of Canada (1997) and the American Physical Society (1983). He is a multiple honorary doctorate (University College of Cape Breton, Royal Military College (D. Sc.), Dalhousie University, University of Chicago (D. Sc.) ).

1969/70 he was Rutherford Fellow and 1998 Killam Research Fellow. In 2003 he received the Tom W. Bonner Prize for nuclear physics for his leading role in educating the Rätselts the Solar neutrinos in the Sudbury Neutrino Observatory. In 2003 he received the Lifetime Achievement Medal of the Canadian Association of Physicists and the same year the Canadian Gerhard Herzberg Gold Medal. In 2004 he received the Bruno Pontecorvo Prize. In 2007 he was Officer of the Order of Canada.
