Cryogen -Free 40mm-Bore 1 TESLA BSCCO Magnet Cooled By Refrigerator
A large-bore, 40mm I.D., (Bi,Pb)2Sr2Ca2Cu3O10 high-Tc superconducting magnet was wound by react & wind technique using flexible multifilamentary wire. The magnet was constructed with 12 double-pancake coils and current leads was made of same wire. A Gifford-MacMahon type refrigerator was used to cool the magnet. The magnet successfully generated 1 Tesla, and was stably operated for over a hundred hours at 21K From these results, it can be expected that non-cryogen magnet using a refrigerator will be the near future application of high-Tc superconducting magnet.
