HTS materials have larger temperature margin than LTS materials. Magnets can be operated around 20 K or higher temperature and can be conduction-cooled by cryocoolers. The cooling structure becomes simpler and the cooling power of a cooler is high. We expect to excite HTS magnets by AC or pulsed currents without quenching. After successful performance tests of prototype magnets, we fabricated two magnets for practical use, an air-core cylindrical magnet and a super-ferric dipole magnet. The former one is used to polarize ultra-cold neutrons and the latter is a switching dipole magnet to deliver accelerated beams to two target stations by time sharing. Their design and operational performance are presented PB - JACoW CP - Geneva, Switzerland SP - 2543 EP - 2545 KW - dipole KW - operation KW - target KW - ion-source KW - power-supply DA - 2017/05 PY - 2017 SN - 978-3-95450-182-3 DO - 10.18429/JACoW-IPAC2017-WEOCB1 UR - http://jacow.org/ipac2017/papers/weocb1.pdf ER -
