Uniform magnetic field was mainly produced by electromagnetic coils in most engineering applications. However, with the development of superconducting technology, the demand for bulk magnets with uniform magnetic field has increased accordingly. In this paper, the key factors affecting the magnetic field uniformity of bulk magnets have been studied experimentally by magnetizing HTS taped...
Because of the well mechanical property and high current capability, geometrically symmetrical strands made from second generation (2G) wires are promising for large scale high-field magnets typically operated at 4.2 K. This paper performs the first tests of a geometrically symmetrical strand in liquid helium and magnetic field of up to 6 T. The critical current and its anisotropy under...
The CORC wires is one of the most ideal structures and will be used in the next generation controllable nuclear fusion magnets due to the advantages of cheap cooling costs, high transport performance and especially simple manufacturing process. In recent years, the cabling process of CORC has been studied in detail by scholars. However, the superconducting magnet in the fusion reactor is made...
Striation is proved to be effective in the magnetization loss reduction for Conductor on Round Core cable. Though it was experimentally observed that the coupling loss contributed to the total magnetization loss of striated CORC cables, simulation models and detailed analysis of the coupling current were still missing. In this study, we present numerical models of striated CORC cables...
With the performance/price improved, there are increasing market demands and power applications for the cost-effective secondary generation high-temperature superconducting REBaCuO Tapes. In the past decade, main challenges are realized for metallorganic solution-derived (MOD) REBaCuO Coated Conductors to achieve higher critical currents with and without applied fields, such as microcracks or...
Abstract—Due to its excellent performance in critical current, REBCO high-temperature superconductor has important applications in superconducting strands, superconducting cables, superconducting magnets, and superconducting transformers. However,high-temperature tapes are subject to unpredictable mechanical stresses in various applications, and excessive stress will cause permanent damage...
The commercial coated conductors (CCs) are at present available in the form of thin strips with high critical current density and excellent mechanical properties. To realize high current carrying capability, several cable conductors were proposed by assembling a large number of CCs. One of them is so called quasi-isotropic strand consisting of four sub-strands by stacking a number of CCs. In...
