  1. 148. M3Or1B-01: [Invited] Study on Irradiation Effect of Insulating Materials for Fusion Superconducting Magnets: Temperature Dependence of Mechanical Strength

    Invited Oral
    1. Introduction
      Insulating materials used in superconducting magnets for fusion reactors are exposed to radiation at the cryogenic temperature of liquid helium temperature. ITER, an experimental nuclear fusion reactor, uses glass fiber reinforced plastic (GFRP), which is a 3:2 mixture of epoxy resin (EP) and cyanate ester (CE) (40 wt.% in CE content) with excellent radiation resistance, as...

  2. 266. M3Or1B-02: Development and performance qualification of two kinds of REBCO CICC for fusion
    Huan Jin (Institute of Plasma Physics, Chinese Academy of Sciences)

    Contributed Oral

    Due to the high current carrying performance under high field and low temperature (<20 K), REBCO tapes exhibit a strong potential of future fusion magnets application. The characteristics, such as anisotropic and multi-layered structure, the stress/strain sensitivity of critical current carrying performance, make them not easy for CICC development, which is very important to achieve practical...

  3. 391. M3Or1B-03: Radiation-Resistant Electrical Insulation for Superconducting Magnets
    Prof. Mani Tripathi (UC Davis)
    12/07/2023, 10:05
    Contributed Oral

    Advancements are required in superconducting magnets for safe, reliable, economic, and environmentally benign operation in high-energy radiation environments such as nuclear fusion devices. Degradation of electric insulation, when exposed to high levels of radiation or high temperature of fusion devices, must be minimal. Innosense LLC (ISL) in collaboration with Florida State University and...

  4. 366. M3Or1B-04: FEM analysis of transient current sharing in REBCO coated conductor cables
    Shengchen Xue (Ohio state university)

    Contributed Oral

    Current sharing is a critical self-protecting mechanism for non-insulating coils and multi-strand cables. Current sharing can be controlled by the contact surface resistance between superconductors. We have found that the contact resistance of REBCO coated conductor can be modified by applying press, sintering, and metal-plating. In our previous work, we conducted steady-state FEM analysis and...
