Abstract Superconducting joints are crucial for second generation high-temperature superconducting (2G HTS) closed-loop coils that work in the persistent current mode (PCM) operation. Here, we report an efficient approach of YBa 2 Cu 3 O 7- σ (YBCO) coated conductors (CCs). The YBCO layer is etched to and from some microchannels, which serve as oxygen diffusion paths during oxygenation annealing (OA), accelerate recovery critical ( I c ) joined two layers. joint 118 A at 77 K with optimized...
Abstract Second-generation high-temperature superconducting (2G-HTS) magnets operating in persistent current mode (PCM) hold great promise for applications such as magnetic resonance imaging. The development of joint-less closed-loop has effectively tackled the challenges fabricating joints REBCO tape. However, certain cannot utilize conventional switches (PCS) and instead require multi-pulse magnetization techniques. This study explores effects field excitation on flux trapping behavior a...
Second-generation high-temperature superconducting (2G-HTS) tapes based on REBa2Cu3O7-x (REBCO, RE: rare earth) materials enable the energy-efficient and high-power-density delivery of electricity, thereby promoting development clean energy generation, conversion, transmission, storage. To overcome weak grain-boundary connection poor mechanical properties these superconductors, a thin-film technology for epitaxy biaxial textures flexible substrates has been developed. In recent years,...
Abstract REBa 2 Cu 3 O 7- δ (REBCO, RE: rare earth) coated conductors (CCs) can generate a powerful magnetic field and are optimal for sustaining the reaction in fusion devices. However, REBCO CCs will inevitably be exposed to neutron radiation during device operation. Transmutation produces gas atoms such as hydrogen affect their properties. In this paper, GdBCO were irradiated by 20 eV deuterium plasma. It was found that irradiation introduced smaller (2–4 nm) pinning sites formed mixed...
Abstract Irradiation can precisely control defects in, and improve the superconducting properties of, REBa 2 Cu 3 O 7− δ (REBCO, RE: rare earth) coated conductors (CCs). Here we report an effective approach for enhancing in-field performance of GdBCO CCs. The critical current density ( J c ) films was significantly improved through cooperative created by co-irradiation with ions protons, especially at low temperatures high magnetic fields. Surprisingly, commercial CCs be nearly doubled....

However, the fabrication application of joints 2G-HTS CCs still pose a significant challenge. This paper reports PCM joint-less coil capturing fields, is called ‘Four Pancake Coil (FPC)’. A novel winding method was developed to...
Abstract Developing closed-loop magnets that operate in a persistent current mode (PCM) is crucial for achieving higher resolution and sensitivity NMR MRI devices. To the best of our knowledge, we report novel multi-pancake (MP) HTS magnet operated on PCM based jointless winding method with superconducting joints REBCO coated conductors (CCs).
