The SCLinac at TRIUMF’s Isotope Separator and Accelerator (ISAC) Facility can provide energies above the Coulomb barrier to create nuclear reactions at our third/final set of experimental facilities. High vacuum is required to support the operation of RF & Cryogenics. This past June, two forms of vacuum protection failed in tandem to adverse results. Two years minimum are needed to regain the accelerating capacity, & there are implications for these experiments in the meantime. This talk will explore what information indicative of such potential vacuum failures we had in advance, what was immediately implemented as temporary additional protection, & opportunities being explored to increase reliability for the future as we upgrade existing & design new accelerators & beamlines.
