A superconducting magnet with an inner diameter of 110 mm, outside diameter of 720 mm, and height of 750 mm, wound from multifilamentary superconductors using a react-and-wind method, has been constructed. The authors succeeded in energizing this magnet up to 16. 2 Tesla and 6. 3 MJ at 4. 2 K without a quench and further fabricated an insert booster magnet to get a higher magnetic field. This insert booster magnet was wound from a Nb//3Sn( plus Ti) conductor in a wind-and-react method; the dimensions were only 34-mm inner bore, 98-mm outside diameter, and 192-mm in height. When this magnet was installed in the abovementioned magnet, the whole assembly produced 17. 1 Tesla at 4. 2 K without quenching, which is a new record for a magnet made of multifilamentary conductors.
