An air-core cyclotron uses HTS coils as magnets. Previous studies have verified the feasibility of beam injection, acceleration, and extraction using this air-core cyclotron. However, some problems remain unsolved. Previous study investigated the beam properties of the cyclotron without considering the HTS coil properties. Also, the fabrication cost and cyclotron volume also need to be reduced for the cyclotron to be put into practical use. In this presentation, a modified air-core cyclotron model is presented, which is designed to satisfy the engineering requirement from HTS coils. The cyclotron volume, the magnetic field property, and its feasibility as a medical cyclotron are discussed.
