14959 TRIUMF           Discovered 1996 May 9 by Spacewatch at Kitt Peak.
The Tri-University Meson Facility (TRIUMF) is a major high-energy physics laboratory in Vancouver, British Columbia. Opened in 1974, the laboratory involves eleven Canadian universities and offers researchers and cancer therapists a variety of beams, including protons and mesons, from its cyclotron.
