Summary

The authors have designed and constructed a 15 T cryocooled superconducting magnet with a vertical room temperature bore of 52 mm. The main components of the magnet are four Nb3Sn superconducting coils, a NbTi superconducting coil, two pairs of bismuth-based oxide superconducting current leads (Bi2223 current lead) and two Gifford-McMahon cryocoolers. The coils were directly cooled down from room temperature to 3.6 K in 114 h by compact GM cryocoolers without liquid helium. The magnet generated a magnetic field of 15.1 T at the centre of the bore and was excited from 0 to 15.1 in 38 min. The magnet succeeded in holding the field at 15.1 T for 24 h at the constant coil temperature of 3.8 K.
