โฆ Synopsis
Self-field AC losses in PbBi-2223 Ag sheathed tapes were measured at different temperatures and frequencies using a lock-in amplifier and a Rogowski coil. For Jd~, the E'(d) characteristics converge rapidly to a frequency independent function, as the losses become dominated by a resistive mechanism such as flux flow

A mini review of our latest results on the a.c. losses in Ag-sheathed PbBi2223 tapes is presented with the focus on self-field losses in a variety of situations and external losses with and without a d.c. transport current. Comparative measurements with the thermometric and electric methods have dem
The AC transport self-field losses at 77 K were investigated on the double-layer cylindrical conductors composed of Ag-sheathed Bi2223 tapes. The multifilamentary tapes as the strands are arranged in a parallel way on the cylindrical former with a diameter of 10.5 mm. The loss values are strongly in
