High-energy (2.7GeV) Au-ions produce columnar tracks in the order of 10nm in diameter, which act as most effective pinning centers. The goal of our irradiation experiments is twofold: firstly, to explore the possible enhancement of critical transport current in the 2223 BPSCCO Ag-tapes currently used as promising conductor material and secondly, to investigate the basic flux pinning mechanism and possible granularity in the samples. The 2223 BPSCCO Ag-tapes were made by the powder in tube technique and irradiated up to doses of 3.5x1011 Au -ions/cm2 at a temperature of 100K. The samples were characterised both by transport jct and magnetization measurements up to 13T and at temperatures ranging from 4.2K to 100K. Granularity of samples was investigated by voltage-current curves. At 77K the irreversibility field derived from jcm could be enhanced by a factor five for orientation Bile. The irreversible magnetization of samples irradiated at an angle of 30° shows a maximum when the field is aligned parallel to the line defects. This behaviour points to the fact that the 2D-pancake vortices are not completely decoupled. The irradiation induced effects will be compared with those obtained on 2212 BSCCO melt textured layers on Ag tape and for different projectiles.
