Title: The Nobel Prize and the Search for the Missing Neutrinos

Speaker: A TRIUMF/SFU scientist, Dr. Rich Helmer, will describe the construction and operation of the laboratory and experiment and the results of the measurements.

Where: Halpern Center  Room 114

Time: 11:30 - 12:30 pm

Abstract: How does the Sun shine? It was the middle of the 20th Century before there was a good understanding of how all that energy is produced. But there was a puzzle - fewer than expected numbers of certain particles (neutrinos) coming from the Sun were detected here on Earth. The discrepancy was resolved by an experiment carried out in a new laboratory built deep underground in a nickel mine near Sudbury, Ontario. For his leadership, the Director of the laboratory, Dr. Art McDonald of Queen's University, was awarded the 2015 Nobel Prize in Physics, the first time a home-grown Canadian has won such a prize for an experiment carried out in Canada.
