Description/Abstract
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 μm and 80 μm a multifilamentary tape of overall thickness 200 μm. The a.c. losses have been obtained by measurement of the loss electric field Et 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 Et(χ) and Ei(χ) 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.
