摘要：
Double-sheathed Bi2Sr2Ca1Cu2Ox (Bi-2212) multifilamentary wire has proven that overall critical current density and mechanical strength, which meet the requirement of the driven-mode operation of the superconducting magnet of 1 GHz-class nuclear magnetic resonance (NMR). For the persistent-current (PC) mode operation, superconducting joint techniques in both cases of oxide-oxide and oxide-NbTi have been developed. It has been clarified that superconducting currents over 300 and 100 A can be transported through the joints, respectively, at 4.2 K in 0 T. (C) 2000 Elsevier Science B.V. All rights reserved.
