We studied effects of interturn spacing on AC losses and DC critical currents of single layer R&W coils wound from multifilamentary, untwisted Bi-2223/Ag tape. The losses at currents below the critical current increased proportional to i = (I0/Ic)n,

Measuring the AC-loss of superconducting cable conductors have many aspects in common with measuring the AC-loss of single superconducting tapes. In a cable conductor all tapes are connected to each other and to the test circuit through normal metal
