 note = {Combined-function superconducting magnets are designed for a heavy-ion rotating-gantry. Superconducting coils of these magnets have surface winding coil structure. To minimize a sagitta, the superconducting magnets as well as their coils have a curved shape. The ten superconducting magnets are installed on the rotating gantry. With the superconducting magnets, the rotating gantry  an transport carbon ions having 430 MeV/u to a patient with irradiation angles of over ±180 degrees, and further is capable of performing threedimensional raster-scanning irradiation. Since the superconducting magnets would be rotated by ±180 degrees, compact cryocoolers are employed for cooling of the superconducting coil. Because the coil has quadrupole and dipole layers, the superconducting magnets can provide both quadrupole and dipole magnetic field. Having employed the combined-function superconducting magnets, we could design the compact rotating gantry, while keeping a large scan size at
the isocenter; the length and the radius of the gantry would be approximately 13m and 5.5m, respectively, which are comparable to those for the existing proton gantries. In this paper, we report the design of the superconducting magnets as well as results of some tests.},
