The large-scale design and manufacture of HTS magnets will require the production and use of thousands of kilometres of HTS tape, supplied by various manufacturers worldwide. A critical step in enabling the production of these magnets is establishing a robust quality control (QC) procedure that can be consistently applied to all received batches of HTS tape before their use in Tokamak Energy’s...

High-temperature superconducting coated conductors (HTS CCs) are essential components in advanced technologies such as high-field magnet, fusion, power transmission, and medical imaging. However, non-uniform thickness along their length and width can severely affect the performance of HTS magnets. Despite the importance of maintaining thickness uniformity, no system currently exists to...

The effect of pinning landscape on critical current in percolative HTS composites is studied. The superconductor contains percolative superconducting cluster carrying a transport current, and artificial pinning centers created by normal-phase fractal clusters. Such a structure provides for effective pinning and thereby raises the critical current because the magnetic flux is locked in finite...

We have fabricated GdBa2Cu3O7-δ (Gd123) thin films doped Gd2CuO4 (Gd214) as artificial pins on LaAlO3 single crystal substrate by fluorine-free metal organic decomposition method and investigated their crystallinity and magnetic field angle dependence of JC-B properties. Recently, we have succeeded in fabricating Gd123 crystals introduced Gd214 as effective artificial pinning centers. TEM...

High-temperature superconductor (HTS) cables have a broad prospect in power transmission applications due to their low loss and high current capacity. The stacked-tape cable is a type of HTS cables wound with parallel-stacked tapes, which shows enhanced thermal stability due to electrical and thermal contacts between tapes. During local quench, the transport current is redistributed among...

Bi2Sr2CaCu2O8+x (Bi-2212) material, the only high-temperature superconducting material capable of being fabricated into isotropic round wires, holds significant potential for the future manufacturing of high-field magnets. In coil design and fabrication, the selection of coil radius is crucial, as an excessively small radius can substantially reduce the coil's current-carrying capacity. This...
