    Invited Poster

    In the manufacture of Nb3Sn coils, the react-and-wind (R&W) method, which uses heat-treated wire to manufacture coils, has advantages, such as no need for heat treatment of the coil. In the R&W method, it is necessary to consider the degradation of the critical current due to Nb3Sn strain, including strain due to winding. Recently, we demonstrated the fabrication of R&W coils with a small...

    Poster

    The high temperature superconducting (HTS) CORC cable has the advantage of high flexibility, making it one of the best candidate cables for producing compact fusion magnets. The intense background magnetic field strength and high current in the fusion device will cause the CORC cable to be subjected to a huge axial tensile electromagnetic force. Excessive axial tensile load can cause...

    Poster

    CORC® ReBCO cables show great potential as conductors for the next generation of high-performance cables in high-field accelerator magnets. However, due to the unavoidable mechanical stresses present in high-field magnet applications, it is important to investigate the deformation and damage these cables sustain under significant transverse compressive stresses. Our previous study demonstrated...

    Poster

    To fulfill the requirement of the high field (＞15 T) and high current carrying capacity (＞40 kA) superconducting magnets for the next-generation fusion reactor, the Institute of Plasma Physics, Chinese Academy of Sciences, proposed two kinds of CICC design concepts, which are both manufactured from a sub-cable. The sub-cable is formed by winding REBCO tape around a stainless steel spiral tube....

    Poster

    This work provides an overview of the experimental and numerical simulation studies on the effects of cool down and external magnetic field-induced mechanical damage in epoxy-impregnated REBCO magnets. Firstly, a circumferential stress numerical model for an epoxy-impregnated REBCO no-insulation (NI) insert magnet was established. The simulation encompasses the cooling process, the influence...

  6. 167. Thu-Mo-Po.05-08: Finite Element Approach for Calculating Stress Distribution in Non-Circular High-Temperature Superconducting Coils
    Zhihua Li (Shanghai Jiao Tong University)

    Poster

    Complex stress distribution arises in high-temperature superconducting (HTS) coil based on REBCO coated conductors, which is affected by the applied winding tension, thermal stress during cooling down, and electromagnetic forces when energizing the coil. The material and structure of bobbin and overband also play an important role. If the stress exceeds a certain range, it can cause...
