High-precision measurements of the ft-values for superallowed Fermi beta decays between nuclear isobaric analogue states provide a number of demanding tests of the electroweak Standard Model, including confirmation of the Conserved Vector Current (CVC) hypothesis at the level of 1.3 parts in 10,000, the most stringent limits on weak scalar current contributions, and the most precise...

High-precision half-life and branching-ratio measurements for the superallowed $\beta^+$ emitter $^{26}\mathrm{Al}^m$ were performed at the TRIUMF-ISAC radioactive ion beam facility located in Vancouver, Canada. The branching ratio measurement was performed with the 8$\pi$ Spectrometer, an array of 20 high-purity germanium detectors, in conjunction with SCEPTAR, a plastic scintillator array...

High precision measurements of superallowed Fermi beta transitions between 0$^+$ isobaric analogue states allow for stringent tests of the electroweak interaction described by the Standard Model. Particularly, these transitions provide an experimental probe of the unitary of the Cabibbo-Kobayashi-Maskawa (CKM) matrix, the Conserved-Vector-Current (CVC) hypothesis, as well as set limits on...

The neutron electric dipole moment (EDM) experiment at TRIUMF aims to constrain the neutron EDM to the 1 x 10^{-27} level in its initial phase of operation. At this level of precision, magnetic stability must be measured at the tens of fT level in the 1 uT operating field of the experiment. Comagnetometers based on Hg-199 and Xe-129 will be used to measure this stability in real time inside...
