We have developed a cryocooler-cooled superconducting magnet for the 29 T hybrid magnet. A cryogen-free hybrid magnet has been designed to generate a magnetic field of 29 T accomplished through combining 10 T created by the cryocooler-cooled superconducting magnet with 19 T by a water-cooled resistive magnet, which is inserted into the room bore of the superconducting magnet. In this work, we developed a 10 T cryocooler-cooled superconducting magnet with 360 mm diameter room bore, because its inner coils are wound with high-strength Nb3Sn wires in consideration of large hoop stress. The cryogen-free hybrid magnet has succeeded in generating 27.5 T, which is world record.
