abstract = {{The spiral inflector steers the beam from the bore in the main magnet into the median plane to achieve the axial injection with an external ion source. In a conventional electrostatic infector, the injection beam energy is limited by the breakdown voltage on the electrodes. At the same time, the injection intensity is also limited by the small aperture in the electrostatic inflector. Magnetic inflector is a promising alternative to overcome these disadvantages. To demonstrate the technology, we use the TR100 main magnet model, a conceptual idea of an H²⁺ cyclotron, as a testbench to study the inflection conditions and optics of the passive magnetic inflector with a cylindrically symmetric structure. A mirror-like field with optimized mirror length and ratio provides a well-focused beam arriving at the median plane. The required magnetic field is produced by shimming a center plug in the injection hole. The space charge effect is also discussed with the simulation of a high-intensity injection beam.}},
