In accordance with this, a compact high-temperature superconducting skeleton cyclotron (HTS-SC) was proposed. HTS-SC is an air-core K-80 cyclotron with a relatively small extraction radius of 40 cm for a 50 MeV H⁺ and 40 MeV D⁺ beam. Owing to its compactness, a relatively high central magnetic field (>2.4 T) remains as a significant challenge for high current injection. This work describes a preliminary study of the injection using a spiral inflector and the central region design of the HTS-SC. Besides, the transverse beam dynamics are also discussed in order to investigate the upper limit of injection current.
