KINGSTON, ON, April 23 /CNW Telbec/ - Queen's University physicist Art McDonald and the team of scientific sleuths from the Sudbury Neutrino Observatory (SNO) have won another prestigious international award for their groundbreaking discoveries about the nature of matter and the structure of the universe. This week at a gala ceremony in Philadelphia, Dr. McDonald will receive the 2007 Benjamin Franklin Medal in Physics, with co-winner Yoji Totsuka from the University of Tokyo, for "the discovery that neutrinos change flavour and have mass." The Franklin Institute Awards Program honours scientists, innovators and entrepreneurs who have made extraordinary scientific achievements, benefited humanity, advanced science, launched new fields of inquiry and increased the understanding of the universe. Past winners of these medals - which date back to 1824 - include Albert Einstein, Alexander Graham Bell, Marie and Pierre Curie, and Orville Wright. More than 100 Franklin Institute Laureates have gone on to receive Nobel Prizes. "This is an outstanding international recognition for SNO Director Art McDonald and the whole SNO Project team," says Vice- Principal (Research) Kerry Rowe. "The Franklin Institute Awards are among the world's oldest and most prestigious comprehensive science awards, with laureates representing some of the most distinguished scientific achievements of the past 180 years." Dr. McDonald and his SNO team solved the 30-year-old puzzle of the "missing solar neutrinos" in their underground laboratory two kilometres below the surface of CVRD-INCO's Creighton Mine in Sudbury, Ontario.

The SNO team includes more than 150 scientists from Queen's, Carleton, Laurentian and Oxford Universities; the Universities of Guelph, British Columbia, Pennsylvania, Washington and Texas; TRIIUMF, Berkeley, Los Alamos and Brookhaven National Laboratories and LIP, Lisbon. "I am honored to accept the Franklin Medal for the scientific results obtained by our SNO team", said Professor McDonald. 1 of 2 8/4/2008 3:15 PM Document View http://proquest.umi.com.myaccess.library.utoronto.ca/pqdweb?index=0&s... "This has been a tremendous collaborative effort over many years. Our success has arisen from the combined talents and hard work of many colleagues and from the tremendous support that we have received from our many international partners." Events surrounding the Franklin Institute Awards this week include seminars, lectures by the nine recipients, interactive demonstrations and educational programs for Philadelphia area students. The Franklin medals will be presented on Thursday April 26. Many of the Canadian SNO scientists are involved in the development of the new SNOLAB international underground science laboratory, expanding the existing SNO research laboratory 2 km underground in INCO's Creighton mine near Sudbury, Ontario. This new laboratory will provide opportunities for very sensitive future measurements of Dark Matter particles thought to make up about 25 per cent of the Universe, as well as other frontier measurements of neutrino properties made possible by eliminating almost all sources of radioactive background.

Giant lab in Sudbury observes tiny neutrinos ; Scientists gather, hoping to understand the nature of matter; [Ontario Edition] Peter Calamai . Toronto Star . Toronto, Ont.: Jun 15, 2000. pg. A.02 Abstract (Summary) Located 2,000 metres below ground in an abandoned mine, the Sudbury Neutrino Observatory is a 10-storey-high detection apparatus centred on a tank containing 1,000 tonnes of heavy water. "Physicists talk about flavours of neutrinos. It's as if the taste buds of the other observatories were inoperative and they don't know if they're eating salt or sugar. Sudbury can uniquely tell whether what is causing the events in their tank is salt or sugar - whether the neutrinos are electron flavoured, muon flavoured or tao flavoured," [John Bahcall] said.

Full Text (477 words) Copyright 2000 Toronto Star, All Rights Reserved. Canada's biggest science experiment, the Sudbury Neutrino Observatory, has passed its inaugural trials with flying colours and is now working full-time to unravel scientific mysteries at both the cosmic and subatomic level. News of the successful breaking-in of the $550-million SNO came as more than 400 physics and astronomy researchers gathered for an international conference in Sudbury to discuss the latest research on the elusive neutrino, one of the elementary particles of nature. Neutrinos are produced naturally in the sun and by cosmic rays hitting the Earth's upper atmosphere. Trillions of them pass through our bodies every second with no effect, because they are little more than a tiny point without electrical charge and with almost no mass. Yet knowing more about these ghostly particles is crucial for understanding the evolution of the universe and the subatomic nature of matter. Costly underground detectors in Japan and Canada are racing to capture and catalogue them and a third one is under construction in Minnesota for $200 million. "SNO is very much on track. We are observing neutrinos from the sun that have all the characteristics you might expect," said Art McDonald, director of the Canadian-lead international project. McDonald said that over the last six months, the SNO has demonstrated that it actually does possess the extreme sensitivity required for its delicate measurements. "When we are ready to make statements about our findings, they will be definitive," McDonald said in an interview. The key challenge for SNO and other neutrino experiments is to find evidence that neutrinos change form as they fly through space or pass through the earth. Physicists believe there are three different "flavours" of neutrinos - electron, muon and tao. Only a transformation from one flavour to another can explain why researchers using more primitive detectors have so far found fewer solar electron neutrinos than theory predicts. Located 2,000 metres below ground in an abandoned mine, the Sudbury Neutrino Observatory is a 10-storey-high detection apparatus centred on a tank containing 1,000 tonnes of heavy water. The rare collisons between neutrinos and the atoms of the heavy water - no more than 20 a day - are captured by 9,500 light 1 of 2 7/27/2008 8:28 PM Document View http://proquest.umi.com.myaccess.library.utoronto.ca/pqdlink?index=1&s... sensors. SNO's unique detection capability was praised by neutrino pioneer John Bahcall, a physicist from Princeton's Institute for Advanced Study who is attending the conference that officially begins tomorrow. "Physicists talk about flavours of neutrinos. It's as if the taste buds of the other observatories were inoperative and they don't know if they're eating salt or sugar. Sudbury can uniquely tell whether what is causing the events in their tank is salt or sugar - whether the neutrinos are electron flavoured, muon flavoured or tao flavoured," Bahcall said.
