Description:

We have designed and fabricated a superconducting magnet using (Bi,Pb)2Sr2Ba2Cu3O10 (Bi-2223) tape conductors. This magnet is a model magnet for a magnetic refrigeration system for hydrogen liquefaction. The magnet consists of a main coil and two shield coils. The shield coils generate opposite direction magnetic fields to reduce the magnetic fields to zero at both ends. The Bi-2223 magnet successfully generated a rated field of 4.8 T at the center at 20 K operation. The performance of the magnet at higher operating temperatures were investigated. The temperature dependence of the magnet performance was well predicted from the temperature and magnetic field dependence of the critical current of the Bi-2223 tape used at the position of the maximum radial magnetic field in the magnet.
