TRIUMF is Canada's national laboratory for particle and nuclear physics. TRIUMF is considered Canada's leading nuclear science research institute, and is consistently regarded as one of the leading subatomic physics research centers on the international level. TRIUMF's headquarter is located on the south campus of the University of British Columbia in Vancouver, British Columbia. TRIUMF houses the world's largest cyclotron,〔http://www.guinnessworldrecords.com/records-7000/largest-cyclotron/〕 a source of 500 MeV protons, which was named an IEEE Milestone in 2010. TRIUMF's activities involve particle physics, nuclear physics, nuclear medicine, and materials science. There are over 450 scientists, engineers, and staff on the TRIUMF site, as well as 150 students and postdoctoral fellows. 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. TRIUMF uses these plans to develop its own priorities. TRIUMF supports only those projects that have been independently peer reviewed and endorsed by the international scientific community. TRIUMF has over 50 international agreements for collaborative scientific research. Asteroid 14959 TRIUMF is named in honour of the laboratory. ==History== 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. 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. 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 . The TRIUMF field goes from 0 to about 320 inches radius with the maximum beam radius of 310 inches. This is because it require a lower magnetic field to reduce EM stripping. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「TRIUMF」の詳細全文を読む スポンサード リンク
