N2 - At RCNP, we have been developing magnets utilizing high-temperature superconducting (HTS) wires for this decade. We built three model magnets, a mirror coil for an ECR ion source, a set of coils for a scanning magnet and a super-ferric dipole magnet to generate magnetic field of 3 T. They were excited with AC/pulse currents as well as DC currents. Recently we fabricated a cylindrical magnet for a practical use which polarizes ultracold neutrons. It consists of 10 double pancakes and the field strength at the center is larger than 3.5 T which is required to fully polarize 210 neV neutrons. It was successfully cooled and excited. One dipole magnet is under fabrication which is used as a switching magnet after the ring cyclotron and is excited by pulse currents. It becomes possible to deliver beams to two experimental halls by time sharing.
