Abstract Frequent linac re-tuning is needed at TRIUMF-ISAC for the delivery of rare isotope beams at a variety of mass-to-charge ratios and beam energies. This operation is of appreciable complexity due to the nature of the accelerator, consisting of a separated function, variable output energy DTL paired with an RFQ. Reference tunes, computed from a variety of beam and accelerator simulation codes, are scaled according to the beam properties, though changing beam parameters at the sources requires manual tuning of matching section quadrupoles. Using an end-to-end envelope model of the machine in the code TRANSOPTR, these tunes can now be rapidly computed, and using beam diagnostic inputs to reconstruct the beam matrix, the model can be used to dynamically re-optimize the machine tune on-line.
