For the development of high magnetic field application using high temperature superconductor (HTS), Bi-2223/Ag tape is one of the promising materials because of its high current capacity and upper critical field. However, Bi-2223/Ag tape shows very strong anisotropy and significant deterioration of critical current in the magnetic field. To explore the possibility of HTS in high field applications, we evaluated the critical current and index value of Bi-2223/Ag conductor in high magnetic field. The Bi-2223/Ag tape was characterized as a function of increasing and decreasing field. The temperature dependence was also examined lower than 4.2 K. All measurements were carried out with hybrid magnet system up to 30 T and the experimental results are reported.Index Terms-Bi-2223/Ag conductor, critical current, high magnetic field, index value.

“…Authors had evaluated c-axis orientation of the whole filamentary area in some silversheathed tapes with deferent I c by rocking curve method using high brilliant synchrotron radiation in SPring-8, which could effectively penetrate both the outer silver sheath and the inner filamentary area [2]. In that previous work I c was inversely correlated with mean misalignment angle that was defined as half width at half maximum in the rocking curve from 2 0 0 diffracting plane.…”

“…Currently, Bi-2223/Ag superconducting tapes are applied to various devices such as power transmission cables, magnets, motors and generators. For realization of such applications, much effort has been made in order to further improve the critical current density of the Bi-2223/Ag tapes [1][2][3][4][5]. It is widely accepted that one important factor for the successful control of the phase formation and the microstructure is the first sintering process of the tapes, which seems to be a critical step for the formation of a desirable final structure [5][6][7][8][9].…”
