摘要：

Measurements have been made of the a.c. self-field losses in PbBi2223 tapes with different core/sheath configurations. Three different tapes have been measured, two monocore tapes with core thicknesses of 25 mu m and 80 mu m and a multifilamentary tape of overall thickness 200 mu m. The a.c. losses have been obtained by measurement of the loss electric field E(l) at a sufficient distance (three times the tape half-width) from the tape axis. Measurements of the spatial dependence of the loss and inductive electric fields E(l)(x) and E(i)(x) have also been made. The results indicate that the 'thin' monocore tape can be adequately described by the thin-rectangle geometry whilst the behaviour of the 'thick' monocore tape lies in between those of the thin rectangle and thin ellipse. The behaviour of the multifilamentary tape follows closely that of a monocore ellipse tape indicating that there is a strong interaction between the filaments.
