“…In 2014, after a decade of operation at ISAC, the 8π spectrometer was decommissioned to make way for the new high-efficiency Gamma-Ray Infrastructure For Fundamental Investigations of Nuclei (GRIFFIN) spectrometer. GRIFFIN is an array of 16 large-volume "clover-type" HPGe gamma-ray detectors, each of which contains 4 large germanium single crystals [12]. GRIFFIN is 17 times more efficient than the 8π for 1 MeV gamma rays and 37 times more efficient by 10 MeV.…”

Superallowed β-decay studies provide some of the best constraints on the possibility of additional quark generations, as well as limits on exotic currents in the weak interaction. The three experimental quantities that are required for performing these tests using 0 + → 0 + nuclear decays (branching ratio, half-life, and Q-value) can all be measured to high-precision with rare-isotope beams at the TRIUMF-ISAC facility in Vancouver, Canada. This proceeding presents a brief outline of the general experimental techniques used at TRIUMF over the past 15 years, as well as recent theoretical advances towards ab-initio isospin-symmetrybreaking corrections to superallowed nuclear decays.
