20T-CSM

This magnet is cryogen-free superconducting magnet with 52 mm room temperature bore. The maximum field of 20T is generated by 6.15 T (427 A) of NbTi coils, 9.41 T (181.5 A) of Nb₃Sn coils, and 4.45 T (191.5 A) of Bi2223 coil. This magnet has the world record of the magnetic field of cryogen-free superconducting magnet. This is the first practical magnet with high-temperature superconducting wires. This magnet supports following experiments: in-field heat treatment, NMR etc.
