The quality of the initial design and engineering and the significance of the result are underscored by the longevity of the TRIUMF cyclotron. Thirty-five years after the first 500 MeV proton beam was extracted, the cyclotron is still the main engine of TRIUMF’s world-leading research program which currently includes meson physics, nuclear physics, nuclear astrophysics, nuclear medicine and irradiation services for industry.|a5=TRIUMF is the world's largest cyclotron, and one of only three intermediate-energy high-intensity accelerators in the world. It pioneered the production and acceleration of H- ions and the use of an AVF (azimuthally varying field) main magnet. | |||
Unlike the world's other two intermediate-energy high-intensity accelerators (located near Zurich and Los Alamos, respectively), the TRIUMF cyclotron can deliver both low-intensity variable energy proton beams and high intensity intermediate energy proton beams with a 100% macroscopic duty cycle. | Unlike the world's other two intermediate-energy high-intensity accelerators (located near Zurich and Los Alamos, respectively), the TRIUMF cyclotron can deliver both low-intensity variable energy proton beams and high intensity intermediate energy proton beams with a 100% macroscopic duty cycle. | ||
The high intensity of the beam also allows the cyclotron to serve as the driver for multiple experiments within the course of a week. The TRIUMF cyclotron’s ability to provide steady, intense and reliable energy beams in a flexible manner has also allowed the facility to become a world leader in providing beams of exotic isotopes using the "isotope separation online" technique. | The high intensity of the beam also allows the cyclotron to serve as the driver for multiple experiments within the course of a week.

During the design and construction of the cyclotron between 1969 and 1974, the sheer scale of the effort required TRIUMF staff and contractors to develop revolutionary computer-assisted design, modelling, measurement and tuning technologies in an era dominated by mainframes and minicomputers. Some of these codes, e.g., RELAX3D - a Laplace and Poisson equation solver, are still in use today. | During the design and construction of the cyclotron between 1969 and 1974, the sheer scale of the effort required TRIUMF staff and contractors to develop revolutionary computer-assisted design, modelling, measurement and tuning technologies in an era dominated by mainframes and minicomputers.

Because of its size, TRIUMF was one of the first particle accelerators to employ a software-based supervisory control and data acquisition system rather than direct linkage of cyclotron and beamline components to a hardware-based control panel. | Because of its size, TRIUMF was one of the first particle accelerators to employ a software-based supervisory control and data acquisition system rather than direct linkage of cyclotron and beamline components to a hardware-based control panel.|a7=The plaque will be installed outside the cyclotron main control room near the site dedication plaque.
