The cyclotron extractor design allows negative ion stripping to extract protons between 35 and 70 MeV. The extractor is consistent with the requirement for high current operation with a minimum of intervention. Twenty-two extractor foils are available in any selection sequence on each side of the cyclotron. The foil exchange is performed in vacuum so that an exchange takes about 2 minutes while obeying safety protocols. The 22 foils are contained in a cartridge that can be quickly exchanged through a vacuum load lock minimizing operator exposure. An added benefit is that the extractor modular design reduces the operational space requirement outside of the cyclotron thus reducing the vault footprint and shielding requirement.
