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 the cooling structure becomes simpler. Owing to a large margin in operating temperature, it is possible to excite HTS magnets by AC or pulsed currents without quenching. After successful performance 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 ultracold neutrons. A dipole magnet is excited by pulse currents in order to deliver accelerated beams to two target stations by time sharing.
