The Chalk River Superconducting Cyclotron

The Chalk River K=520, 4-sector, superconducting cyclotron1, is designed to accelerate all ions from Li (to 50 MeV/u) to U (to 10 MeV/u) using a 13 MV tandem as injector. Concurrent with the design of the integrated accelerator facility we have been testing major components - specifically the radiofrequency accelerating structure and the cyclotron magnet. The project has now been approved and site preparation is underway. This paper reports on the cyclotron assembly, initial cooldown of the cryostat and first magnetic field measurements.
