The SCSC-IFB cable is a novel round HTS cable concept, composed of copper-plated multifilament (striated) coated conductors with inter-filament bridges. Filamentizing coated conductors and winding them helically on a metal core play roles similar to filamentizing and twisting in LTSs, effectively reducing magnetization and AC loss. A peculiar feature of the SCSC-IFB cable is the use of...

REBCO-based high-temperature superconducting (HTS) tapes are strong candidates for next-generation AC power applications due to their high current density and compact geometry. However, AC losses remain a major obstacle to their widespread deployment. Patterned Superconductors for AC Loss Minimisation (PSALM) tapes offer a promising solution by embedding Roebel-inspired patterns directly...

REBCO conductors with high critical currents and high engineering current densities (Je) in magnetic fields of 20 T and above are needed for several applications such as particle accelerators and fusion magnets. REBCO tapes made by our Advanced Metal Organic Chemical Vapor Deposition (MOCVD) method have yielded critical current over 1830 A/4-mm-width at 4.2 K, 20 T in short samples and over...

Enhancing the critical current density (Jc) of polycrystalline SmFeAsO1-xFx (Sm1111) superconductors remains a major challenge because intergranular current transport is severely limited by weak-link grain boundaries, porosity, and incomplete phase formation. High-pressure processing offers a unique opportunity to overcome these limitations by simultaneously controlling phase evolution,...

Conductor on Round Core (CORC) cable, made from High-Temperature Superconducting (HTS) ReBCO tapes, is one of the leading candidate for nuclear fusion applications due to its high critical current density, high critical magnetic field, and ease of manufacturing [1]. However, its electrical performance is critically dependent on the mechanical integrity of the ReBCO layer, which must remain...

High-pressure synthesis is an effective strategy for enhancing the superconducting performance of iron-based superconductors by improving phase formation, microstructure, and grain connectivity [1-2]. In this work, we systematically investigate the effect of in-situ synthesis pressure on the structural, microstructural, and superconducting properties of the optimally fluorine-doped Pr-based...
