A cryogenfree superconducting mugnet (CSM) has been reali/ed using Bisystem high temperature superconducting current leads. Although conventional low temperature superconducting magnets wound with NhTi and NbjSn wires are utilized, liquid helium is no longer required for a magnet operation. Up to now, various kinds of cryogenfree superconducting magnets such as a high field 15 TCSM, a large bore 5 TCSM with a 300 mm room temperature bore, and a unique high field Xray diffraction apparatus combined with a splitpair 5 TCSM have been successfully developed. Moreover, a splitpair CSM for neutron scattering und n high temperature operation CSM ;it 20 K employing Agshea t lied D i 2223 tape have been demonstrated, t is expected that the further rapid progress in a cryogenfree superconducting magnet will be made and high field applications will be enlarged in the near future.
