Description
An axial injection system has been developed for the CIM30 cyclotron, which is designed to accelerate α-particles up to 30 MeV for medical isotope production of At-211. This system transports a 50–60 keV α-beam from an external ion source into the cyclotron center. Both transverse and longitudinal focusing are applied to ensure high beam extraction efficiency and quality. The injection line consists of dipole magnets, a buncher system, a beam diagnostics system, a vacuum system, Glaser lens, and a spiral inflector. The buncher and the spiral inflector are identified as key components. Their physical design and beam dynamics characteristics are described in detail. Additionally, mechanical and magnetic tolerances of the injection system are analyzed, providing a basis for engineering design.
