Since the introduction of superconducting coils into cyclotron technology, the overall size and efficiency of a cyclotron has improved significantly over the past decade. These advantages result in its widespread for various medical applications. Therefore, High-Temperature Superconducting Skeleton Cyclotron (HTS-SC) was proposed to deliver a high intensity H+ beam for accelerator-based multi-port Boron Neutron Capture Therapy (AB-mBNCT) system and the production of medical radioisotopes (RI). HTS-SC is a unique air-core K-80 cyclotron. It consists of a series combination of air-core high-temperature superconducting (HTS) coils for magnetic field optimization. This work discusses the overview of HTS-SC, including the general configuration, beam dynamics, as well as a brief description of its sub-components. In order to achieve a relatively high intensity of such a compact machine, particular attention is given at injection and extraction, where the beam condition is volatile and beam loss is serious. Finally, this work concluded the feasibility of HTS-SC to inject, accelerate and extract more than 0.5 mA H+ for AB-mBNCT and RI production.
