Abstract

The effect of partial cracking on critical current density (J c ) has been modelled for Agsheathed superconductor tapes. Effects of crack length and density on current-voltage characteristics and J c were evaluated for monofilament and multifilament tapes. The results show that a single long crack is more harmful than numerous small cracks. Multiple small partial cracks (less than 20% of core dimension) can be present in the Bi 2 Sr 2 Ca n-1 Cu n O 2n+4 (BSCCO) before J c degradation is observed. In general, a multifilament tape can withstand cracks better than a monofilament tape.
