Abstract
We have been developing magnets utilizing hightemperature 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 (UCN). The field strength at the center is higher than 3.5 T which is required to fully polarize 210 neV neutrons. The magnet was used to polarized UCN generated by the RCNP-KEK superthermal UCN source. One dipole magnet is under fabrication, which is used as a switching magnet after the RCNP ring cyclotron and is planned to be excited by pulse currents. It becomes possible to deliver beams to two experimental halls by time sharing.
