TRIUMF’s accelerator facilities are expanding, with the new radioactive or rare isotope beam facility, the Advanced Rare Isotope Laboratory (ARIEL), set to come online in 2026. The 520 MeV Cyclotron has been operational for 45 years and will produce one of the driver beams for ARIEL. Several of the cyclotron’s support and subsystems are (near) original and have reached the end of life. These include emergency power, cooling water, HVAC systems, and magnet power supplies. These systems cause considerable downtime and no longer meet the requirements of the laboratory. There are efforts underway to upgrade or refurbish many of these systems. This poster presents a few of these projects and how these projects impact the reliability of beam delivery at TRIUMF.
