Over a 12 year period, the 8π γ -ray spectrometer at the TRIUMFISAC facility was a world unique device for β-decay studies. Equipped with a variety of auxiliary devices, it was used in studies of Fermi superallowed β+ emitters, and nuclear structure studies far from stability and those employing high-statistics measurements. In the present contribution, this latter use is highlighted with examples of recent data obtained in the decay of 122Cs to 122Xe. The 8π spectrometer was replaced with the much more powerful GRIFFIN facility in 2014, ensuring world-leading capability for γ -ray spectroscopy following β decay at TRIUMF-ISAC for the next generation. Examples that highlight GRIFFIN's capabilities are given.
