	At RCNP, we have been developing magnets utilizing first generation HTS wire for this decade. HTS materials have advantages over LTS materials. Magnets can be operated at 20 K or higher temperature and cooled by cryocoolers. The cooling structure becomes simpler and the cooling power of a cooler is high. Owing to a large margin in operating temperature, it is possible to excite HTS magnets by AC or pulsed currents without quenching. Three model magnets were fabricated; a mirror coil for an ECR ion source, two sets of race track coils for a scanning magnet, and a 3T super-ferric dipole magnet having a negative curvature. They were excited with AC and pulse currents as well as DC currents and their performance was investigated. After successful tests of proto type models, two magnets have been fabricated for practical use. A cylindrical magnet generates a magnetic field higher than 3.5 T at the center to polarized 210 neV ultra cold neutrons. A dipole magnet is excited by pulse currents in order to deliver accelerated beams to two target stations by time sharing. Their design and operational performance are discussed.
