Cable-In-Conduit-Conductor (CICC) is particularly suitable for applications requiring both high magnetic fields and efficient current transmission, such as in particle accelerators, magnetic resonance imaging (MRI) systems, and high-field magnets. To further enhance the current-carrying capability of CICC, we developed a CICC conductor in which the CORC strands are made up of 24 layers, with a...

The development of high-current cables made of rare-earth barium copper oxide (REBCO) coated conductors is a key technology for high-field accelerator magnets above 16 T. A flexible round REBCO cable has been proposed as one of the candidates for the high-current cable. This round REBCO cable consists of many coated conductors wound in multiple layers in a helical configuration on a metal...

High-temperature superconducting Conductor on Round Core（CORC）cable, with advantages of strong current-carrying capacity, low loss, light weight, and good bending performance, has become an excellent choice for winding high-field magnets and meeting the requirements of magnetic field shaping. In particular, CORC cable has great potential in manufacturing the Central Solenoid magnet (CS magnet)...

Compared with traditional reactors, superconducting reactors have the advantages of small volume, light weight, high efficiency and low harmonics, which are more conducive to improving the stability of the power system. During operation, transport AC loss may bring unexpected huge burdens to the cryogenic system, thus affecting its operational stability. Accurately evaluating the AC loss...

In order to satisfy the magnetic requirements of high current, high-field and excellent mechanical properties of magnet systems in future fusion devices, a compact high-current-carrying conductor structure inspired by quasi-isotropic strand (QIS) and twisted stacked tape cable (TSTC) structures is proposed in this paper. By placing three groups of equal volume but different direction HTS...

Spiral copper-plated striated coated-conductor (SCSC) cables, in which copper-plated multifilament coated conductors are wound around a metal core with a circular cross-section, are characterized by both low ac losses and high robustness against thermal runaway or quench, as well as large current capacity and excellent mechanical flexibility. Taking advantage of these features, SCSC cables are...

High energy physics magnets use superconducting cables to decrease their inductances which limit their induced voltages during magnet ramp rates and quenches. For HTS strands, the minimum quench energy (MQE) is quite large. Heating due to small defects within the cable can be mitigated by strand-to-strand current sharing. In this case of particular interest are REBCO tape stacks, Roebel and...

We have been developing the SCSC cable (Spiral Copper-Plated Striated Coated-Conductor Cable) consisting of copper-plated striated (multifilament) coated conductors wound spirally around a round core. Its spiral geometry decouples filaments electromagnetically against transverse magnetic fields like twisted low Tc superconductor wire and, then, reduces AC loss. The copper helps current sharing...

Limited by filament size, the dimensions of Rare-earth Barium Copper Oxide (ReBCO) cables are usually comparable to the width of the constitutive tape strands. Resultantly, the distribution and redistribution of currents amongst strands can have a strong impact on the behaviors of the cable, including current-voltage characteristics and in-field performance. In this study, we present a...
