  1. 485. M2Po2B-02: Numerical study of the clamping system and mechanical stress amplitudes in powerline busbars of SIS100 synchrotron fast ramped superconducting magnets
    Prof. Artur Iluk (Wrocław University of Science and Technology)

    Poster

    The mechanical stress in the superconducting magnets due to clamping forces and Lorentz forces have been investigated by many researchers. The main issue is a critical current and quench induced by a magnetic field and mechanical strains in the busbars. Unfortunately, much less attention was paid to the mechanical stress and stability of the busbars that power the magnets. The self-induced...

  2. 455. M2Po2B-03: Magnetization, Flux Creep, and AC Loss in a Bi-2212 Conductor for Particle Accelerator Applications

    Poster

    Bi-2212 Rutherford cables are under consideration for construction of the next generation of high-field magnets for particle accelerators. The critical current has been increased to a level sufficient for these magnets, but field errors due to magnetization and flux creep is still a concern, especially since these can be higher for HTS materials than Nb-Ti or Nb3Sn. The...

  3. 163. M2Po2B-04: Simulations for the fault current limiting operation of a long-length YBCO CORC® superconducting cable cooled by Helium gas
    Dr Linh Nguyen (Los Alamos National Laboratory, Los Alamos, NM 87544 USA.)
    11/07/2023, 14:00
    Poster

    The CORC® superconducting cables composed of YBCO coated conductors are of great interest for power transmission applications due to many advantages such as high power density, lightweight and low loss. The flowing cold Helium gas can be used to cool HTS cables down to 50 K to significantly improve their current carrying capacity. Coupled electromagnetic-thermal finite element (FE) simulations...

  4. 409. M2Po2B-05: CLIQ Quench Protection System for a MgB2 Segment Coil for MRI Applications
    Xianhao Zhang (The Ohio State University)
    11/07/2023, 14:00
    Poster

    In this work, we performed studies of quench protection relevant to MgB2 based 3T conduction cooled magnetic resonance imaging (MRI) machine. We modelled a conduction cooled MgB2 whole body, segmented coil MRI design. The overall design had 3T in the bore, with 10 ppm homogeneity in a 49 cm DSV, total magnet length = 1.37m, total conductor length = 121km, operating current Iop = 287 A,...

  5. 642. M2Po2B-06: A 3D/2D mixed-dimensional structural model and electro-mechanical phenomenological model for REBCO coated conductors
    Prof. Peifeng Gao (Lanzhou University)
    11/07/2023, 14:00
    Poster

    As typical REBCO conductors contain laminated high-aspect-ratio (HAR) thin films, such as the silver, REBCO, and buffer layers, effective modeling is a significant challenge. In this study, the three-dimensional/two-dimensional (3D/2D) mixed-dimensional modeling method is adopted to build a novel elastic-plastic structural mechanics model, which realizes the entire simulation of fabrication...

  6. 647. M2Po2B-07: A hierarchical delamination model for epoxy-impregnated REBCO superconducting pancake winding
    Dr Hanxiao Guo (Lanzhou University)
    11/07/2023, 14:00
    Poster

    Rare-earth barium copper oxide (REBCO) coated conductor (CC) tapes are promising for high-energy and high-field applications. In epoxy-impregnated REBCO superconducting windings, due to the weak c-axial strength of REBCO CC tapes, delamination induced by thermal mismatch stress and Lorentz force significantly threatens stable operation. As the epoxy-impregnated REBCO superconducting magnets...
