“…Remarkably high critical current values of 2247 and 2119 A/4 mm width have been measured at 4.2 K, 14 T for the two samples. These values are higher by a factor of >2 than the best reported value in 3.2 μm thick, 20 mol% Zr added GdYBCO film processed in three passes using conventional MOCVD and more than five times higher than the commercial HTS tapes reported in a recent study [35,43].…”

“…The critical current of commercial coated conductors covers a wide range of values, from about 100 A to over 250 A at 77 K, self-field (for a 4 mm wide tape). Also at low temperature, in field, the range covers almost a factor 7: a glimpse of the situation is plotted in figure 3 for various tapes measured in the last five years at the Swiss Plasma Center, together with recent values from [53] and [54]; the reader can find more characteristics and specifications in [52]. In order to improve the critical current values in field some manufacturers add artificial pinning centres (APC) in the ceramic layer; this technique was first introduced by SuperPower, adding…”

High Temperature Superconducting (HTS) materials have the potential to generate magnetic field beyond the level obtainable with Low Temperature Superconducting (LTS). This review reports the past and present R&D on HTS cables and conductors for high field tokamaks, accelerator dipoles and large solenoids. Among the HTS wires and tapes available commercially, coated conductor tapes are the most appealing because of the outstanding critical strength and large improvement margin. Limitations are the weakness against peeling and shearing and the short piece length. The prices for technical superconductors are reviewed because they play an important role in large projects; moreover the perspective of industrial production of HTS wires and tapes is discussed considering the historical development of the LTS wire market. Various designs have been proposed for HTS cables and conductors: some are better suited for soft materials, while others can exploit the anisotropy of coated conductors (by aligning the tape with the field), providing the highest current density. The last decade has seen an increase in the size and complexity of the prototypes; however some peculiar features of HTS, such as high stability margin and high mechanical limits, have not yet been fully incorporated in the designs: for example the transposition requirements for HTS have not yet been studied in detail. Several facts indicate that tapes (even if anisotropic) can be used for manufacturing cables and magnets of any size and have advantages with respect to round wires.
