TRIUMF is Canada’s national laboratory for particle and nuclear physics located on the University of British Columbia campus in Vancouver, British Columbia. TRIUMF houses the world's largest superconducting cyclotron, a particularly "luminous" source of 500 MeV protons.
The name, formerly abbreviated from TRI-University Meson Facility, is now no longer an appropriate acronym as TRIUMF is now owned and operated by a consortium of fifteen Canadian universities. The consortium runs TRIUMF through a contribution of funds from the National Research Council of Canada, and makes TRIUMF’s facilities available to Canadian scientists and to scientists from around the world. Many Canadian university scientists collaborate in multi-institutional groups, which in turn collaborate with international groups to mount large-scale projects at TRIUMF and at national laboratories in Europe, the United States, and Japan. The current director of TRIUMF is Dr. Nigel Lockyer, who began his term on May 1, 2007.
Asteroid 14959 TRIUMF is named in honour of the laboratory.
