The powder-in-tube process has been used to fabricate long lengths of flexible, high J[sub c], silver clad Bi-2223 HTS conductors. By improving thermo-mechanical processing and precursor powder preparationwe have succeeded in achieving J[sub c]'s exceeding 4 [times] 10[sup 4] A/cm[sup 2] at liquid nitrogen (77K) and > 10[sup 5] A/cm[sup 2] at liquid helium (4.2K) and liquid neon (27K) temperatures for short tapesamples. Detailed measurements with high applied magnetic fields are reported. Several long tapes up to 10 meters in length have also been fabricated and co-wound into small superconducting pancake coils using the wind-and-react'' approach. Transport measurements at 77K and 4.2K for these coils are also reported.
