Laser spectroscopy

The unique TRIUMF-based Collinear Fast-Beam Laser Spectroscopy facility is using the smallest changes in electrons’ quantum-level jumps to map the extreme frontier of nuclear structure in rare isotopes. The core challenge in studying these extreme nuclei, ones with lopsided ratios of neutrons and protons, is that they’re very short-lived. The rare isotope must be produced, … Continued

Science Technology Facility

TRIUMF’s Science Technology Facility provides the expertise and specialized construction capacity for the design-to-installation creation of state-of-the-art particle detectors. The Science Technology Facility’s two dozen staff have contributed to the fabrication, in part or full, to more than a dozen detectors for subatomic particle and nuclear physics experiments based at TRIUMF and Canadian and international … 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


The BRIKEN (Beta-delayed Neutron Measurements at RIKEN) international collaboration is providing a new window into our stardust origins by making the first-ever decay measurements of many of the rare neutron-rich isotopes central to heavy element formation in stars.  BRIKEN, a TRIUMF collaboration, is based at the RIKEN Nishina Center for Accelerator-Based Science in Wako, Japan.   The … Continued


With the DSL (Doppler Shift Lifetimes) facility, TRIUMF scientists are shining light on element formation in stars by measuring nuclear excited states that last for only femtoseconds, thousandths-of-a-trillionth-of-a-second.  Collaboratively with facilities including DRAGON and EMMA, the DSL facility is a core part of TRIUMF’s nuclear astrophysics research program.  A nuclear-excited state is a nucleus that contains excess energy and spontaneously releases it, for example as a gamma ray, to reach a more stable … Continued


With TUDA (the TRIUMF U.K. Detector Array), the TRIUMF UK Detector Array, TRIUMF scientists and international collaborators are making critical insights into key stellar element formation pathways that can only be experimentally studied using accelerated rare isotopes.  TUDA, and facilities such as DRAGON and EMMA, are core parts of TRIUMF’s astrophysics research program. TUDA’s precision astrophysics nuclear reaction measurements are used by researchers worldwide and integrated into the latest stellar computational models, providing astronomers with … Continued


TRIUMF’s unique DRAGON (Detector of Recoils And Gammas of Nuclear Reactions) facility is giving astronomers a clearer view of our stardust origins by simulating the rapid nuclear reactions that take place in exploding stars. It is the only facility in the world capable of experimentally measuring many of these astrophysical reactions.   DRAGON is a recoil mass … Continued


TRIUMF’s IRIS (ISAC Charged Particle Reaction Spectroscopy Station) experimental facility is giving physicists a unique view of the strong force and unusual transformations in nuclear structure when nuclei are pushed to the extreme.  The research team, led by Saint Mary’s University physicist Rituparna Kanungo, is using ISAC-II produced rare, short-lived isotopes to view the inner … Continued


With TIGRESS (TRIUMF-ISAC Gamma Ray Suppressed Spectrometer), an in-beam gamma ray spectrometer, TRIUMF scientists are opening a new era of high-precision nuclear structure experiments with rare isotopes.  Much of physicists’ understanding of nuclear structure has come from gamma ray spectroscopy. TRIUMF’s unique gamma ray spectroscopy program with TIGRESS and GRIFFIN is extending this to rare, radioactive isotopes.   Using ISAC-II’s high-energy rare isotope beam, TIGRESS experiments involve smashing isotopes into a target to energize the … Continued
