TRIUMF’s Superconducting Radiofrequency (SRF) facility is Canada’s only centre for the research, design, testing, and assembly of SRF accelerator technologies. Since 2000 the TRIUMF SRF team has collaborated with university research and laboratory partners worldwide, and designed, assembled and maintained TRIUMF’s two SRF accelerators, the ISAC-II Superconducting Heavy-Ion linear accelerator (SC-linac) and the ARIEL Electron … Continued

Rare Isotope Beam Delivery

From their origins in targets and ion sources, TRIUMF’s rare isotope beams (RIBs) travel on to navigate two important technologies: mass separators and charge breeders. The singly-ionized rare isotopes enter a High-Resolution Mass Separator (HRS) in order to create a purified, high-intensity RIB of ideally just a single selected isotope. From the mix of products emerging … Continued

Targets and Ion Sources

At its core, a rare isotope production target is a material, such as uranium carbide, that when irradiated undergoes nuclear reactions that produce rare isotopes. TRIUMF’s two target drivers, accelerated protons and electrons, can each be used with a variety of target materials to induce different kinds of nuclear reactions and produce different types and … Continued

Post-target accelerators

TRIUMF’s rare isotope production facilities also include a series of three different post-target accelerators that accelerate heavy ions to energies required by TRIUMF experiments, for example mimicking the energetic conditions of rare isotopes in an exploding star. The three accelerators operate sequentially in a way analogous to the gearing system in a car with a … Continued

e-linac: Electron Linear Accelerator

The second driver for TRIUMF’s rare isotope beam program is the new electron linear accelerator (e-linac), the world’s highest power e-linac for rare isotope production, which will come fully online in 2021. Unlike the spiral of a cyclotron, the 25-meter-long e-linac accelerates electrons in a straight line. Starting with a fingernail-sized electron source, the e-linac … Continued

520 MeV Cyclotron

TRIUMF’s 520 MeV cyclotron, one of the world’s largest cyclotrons, accelerates negative hydrogen ions to 75% the speed of light to produce intense proton beams for rare isotope production and a variety of other particle physics applications. The 18-meter diameter, clamshell-shaped 520 MeV cyclotron structure is iconic in design, construction, operation and scientific output. The … Continued


The AWAKE (Advanced Proton-Driven Plasma Wakefield Acceleration Experiment) international collaboration is the first experiment exploring the use of existing high-energy proton accelerators to power a next-generation of ultra-compact electron accelerators. Based at CERN near Geneva, Switzerland, AWAKE is one of several TRIUMF-CERN collaborations, along with the major ALPHA and ATLAS collaborations. High energy particle physics … Continued


At TRIUMF’s unique βNMR (beta-detected Nuclear Magnetic Resonance) facility, scientists are using radioactive isotopes to take inside-out, atomic-level snapshots to guide the way to new materials and medicines. βNMR (the Greek-letter β is pronounced ‘beta’) is a next-generation form of the better-known Nuclear Magnetic Resonance (NMR), one of the most important tools in science for characterizing … Continued
