We have proposed a new type superconducting power supply, cylindrical type magnetic flux pump (CTMFP) for high field magnet. This paper describes the structure and operating principle based on pumping equations, and also presents its fundamental characteristics by the finite element method (FEM). Since the proposed CTMFP that consists of three phase armature coils, an LTS Nb foil and a cylindrical permanent magnet can easily produce homopolar traveling fields, a pumping current can be generated in the closed superconducting loop. Due to its simplicity structure, the CTMFP has more efficient operation compared with already developed magnetic flux pumps. From the simulation results, appropriately combined conditions of AC current and intensity of the permanent magnet to realize the homopolar traveling magnetic field were obtained.
