Description

The TRIUMF 520 MeV cyclotron continues to serve as a reliable driver for high-intensity proton beams, supporting a broad range of applications. To sustain and enhance high intensity operation, recent developments have focused on reducing beam losses and improving overall reliability. This talk will highlight progress in several key areas: upgrades to the new injection beamlines; cyclotron tune optimization and the avoidance of linear coupling resonances to suppress beam spills and reduce component activation; and the implementation of a refined degaussing procedure for the main magnet to improve reproducibility and ensure accurate restoration of the isochronous field. In addition to reporting on this progress, the talk will also present some of the ongoing technical and institutional challenges, including beam matching with full 6D coupling through the inflector, nonlinear resonance study, and the broader issue of sustaining expertise around mature accelerator facilities.
