TRIUMF is Canada's national particle accelerator centre. It is considered Canada's premier physics laboratory,[1] and is consistently regarded as one of the leading subatomic physics research centers on the international level.[2] Owned and operated by a consortium of universities as a joint venture, TRIUMF is located on the south campus of one of its founding members – the University of British Columbia in Vancouver, British Columbia. TRIUMF houses the world's largest cyclotron,[3] a source of 520 MeV protons, which was named an IEEE Milestone in 2010.[4] TRIUMF's accelerator-focused activities involve particle physics, nuclear physics, nuclear medicine, materials science, and detector and accelerator development.

There are over 500 scientists, engineers, technicians, tradespeople, administrative staff, postdoctoral fellows, and students on the TRIUMF site. The lab attracts over 1000 national and international researchers every year and has generated over $1B in economic impact activity over the last decade.

TRIUMF scientists and university-based physicists develop and implement Natural Sciences and Engineering Research Council's (NSERC) long-range plan for subatomic physics.[5] TRIUMF uses these plans to develop its own priorities. TRIUMF has over 50 international agreements for collaborative scientific research.[6]

TRIUMF's cyclotron infrastructure has enabled the laboratory's proton therapy cancer treatment centre – the only one of its kind in Canada.[7] TRIUMF's proton therapy centre is operated in conjunction with the British Columbia Cancer Agency (BCCA) and the University of British Columbia Department of Ophthalmology.[8] The TRIUMF Proton Therapy Centre specializes in the treatment of ocular melanoma and uses protons from the laboratory's 520 MeV cyclotron to irradiate cancerous tumors with high precision, thus destroying the tumor while leaving the surrounding tissue unharmed.[9]

Asteroid 14959 TRIUMF is named in honour of the laboratory.[10]


TRIUMF was founded in 1968 by Simon Fraser University, the University of British Columbia, and the University of Victoria in order to meet research needs that no single university could provide. The original acronym, stemming from the name TRI University Meson Facility, was dropped and is no longer used to reflect TRIUMF's current state as a consortium of 19 universities. TRIUMF currently has 19 member and associate universities from across Canada.[11]

TRIUMF entrance

Since its inception as a local university facility, TRIUMF has evolved into a national laboratory while still maintaining strong ties to the research programs of Canadian universities. The science program has expanded from nuclear physics to include particle physics, molecular and materials science, nuclear medicine, and accelerator research and development.

TRIUMF's 520 MeV cyclotron was officially commissioned on February 9, 1976 by Pierre Trudeau, the 15th's Prime Minister of Canada. At the commissioning ceremony, he said "I don't really know what a cyclotron is, but I am certainly very happy Canada has one."[12]

Before the Riken SRC (superconducting ring cyclotron) was built, TRIUMF was the world's largest cyclotron in terms of weight and beam or magnetic field radius. The Riken SRC is now heavier than the TRIUMF cyclotron, but TRIUMF has the largest beam radius and the largest vacuum tank. The Riken magnetic field covers from 3.5 m to 5.5 m radius with the maximum beam radius of about 5 metres (200 in). The TRIUMF field goes from 0 to about 320 inches radius with the maximum beam radius of 310 inches. This is because it requires a lower magnetic field to reduce EM stripping.

Laboratory directors

Since its inception, TRIUMF has had eight directors overseeing its operations.

  • John Warren – 1968–1971
  • John Reginald Richardson – 1971–1976
  • Jack Sample – 1976–1981
  • Erich Vogt – 1981–1994
  • Alan Astbury – 1994–2001
  • Alan Shotter – 2001–2007
  • Nigel S Lockyer – 2007–2013
  • Jonathan A Bagger – 2014–present
