It is a compact and fully automated isochronous cyclotron accelerating H⁻ up to 9,2 MeV. Based on the successful design history and return of experience of the Cyclone® KIUBE, the Cyclone® KEY design has been focused on compactness (self-shielding enabled), cost effectiveness and ease of installation, operation and maintenance. The innovative design consists in the interoperability of the different subsystems: the magnet, the RF system, the vacuum system, the ion source, the stripping extraction, and target changers (with up to three targets). First beam tests results will also be presented.
