Abstract
By optimising the tape fabrication process, high critical current dens ities over long lengths (up to 25 m) of Bi,Pb(2223) Ag-sheathed tapes were reproducibly achieved. The J(c) values of multifilamentary tapes (up to 55 filaments) ape typically in the range of 25-30 kA/cm(2) at 7 7 K, while J(c) values up to 35 kA/cm(2) were recently achieved for mo nofilamentary tapes of 0.5 m in length. Detailed measurements of the t ransport properties of short tapes as well as of test pancakes are pre sented. The employment of these tapes in the fabrication of supercondu cting coils have been also discussed.
