抄録

Bi-2223/Ag double pancake coil with a stack number of 6 is analysed with the use of quantitative J-E expressions that can describe the magnetic anisotropy as well as temperature dependence of J-E curves in the tape. The practical multifilamentary structure of the tape is directly considered for the precise analysis. It is shown that the magnetic anisotropy greatly and complicatedly influences the distribution of the current density inside the tape as well as that of the electric field in the coil. Furthermore, the current transport performance of the coil is also shown to be largely influenced by the magnetic field generated by the coil itself.
