The results of AC loss measurements of silver-sheathed (TI,Pb,Bi)-1223 tapes prepared by the powder-in-tube method are presented. Losses arising from an external AC magnetic field are compared with those generated by AC transport currents (self-field losses). Experimental results, obtained by both m
The transport critical current distribution of a rolled Bi(2223) tape with jc(77 K, 0 T) = 28 kA/cm 2 has been found to vary from 20 kA/cm 2 at the tape centre to 53 kA/cm 2 at the tape sides. The self-field generated by the high currents flowing in this tape has been studied at the liquid-nitrogen
The effect of partial cracking on critical current density (J,) has been modelled for Agsheathed superconductor tapes. Effects of crack length and density on current-voltage characteristics and J, were evaluated for monofilament and multifilament tapes. The results show that a single long crack is m
