11) Cryogenfree 23 T Hybrid Magnet

@@We are now constructing a cryogenfree 23 T hybrid magnet at the High Field Laboratory for Superconducting Materials, Institute for Materials Research, Tohoku University. The world's first cryogenfree hybrid magnet combined with an inner 15.5 T water-cooled resistive magnet was tested, and at present, the central magnetic field of 21.5 T was generated in a 52 mm room temperature experimental bore. The magnetic force field of 2270 T2/m was obtained. Using a YAG laser combined with the cryogenfree hybrid magnet, a containerless melting experiment in magnetic levitation was performed to fabricate a field-oriented paraffin fine ball.
