    Invited Oral

    High quality materials are essential to the success of large magnet projects. National High Magnetic Field Laboratory (NHMFL) has been funded by the US National Science Foundation to design a 40 T superconducting magnet which uses REBCO coated conductor tapes for the insert coil winding co-wound with copper and stainless-steel tapes. Characterization and incoming quality assurance (QA) testing...

    Invited Oral

    Research on high-field magnets has always been instrumental for high energy colliders. Amongst many aspects in magnet design and construction, the electrical insulation system is of paramount importance to ensure required performance. Concerning the manufacturing of Nb3Sn magnets, superconducting coils undergo a vacuum impregnation process which requires the impregnation system to have a low...

    Invited Oral

    The SPARC tokamak requires large, strong, and tough cryogenic structures to enable its high-temperature superconducting magnets. Stresses induced in these structures scales linearly with magnetic field, driving the selection of a high strength (Sy>900MPa) and high toughness (KIC>200MPa*m1/2) austenitic stainless steel. A custom composition of 316LN(H) has been chosen as the primary structural...

  4. 505. M3Or4B-04: [Invited] Cryogenic mechanical properties of large forgings for high field fusion magnets
    Markus Kind (Rolf Kind GmbH)
    21/05/2025, 17:25
    Invited Oral

    Nuclear fusion represents a promising pathway to a sustainable and virtually inexhaustible energy future, offering a low-carbon alternative to conventional power sources. Achieving fusion relies on high-field superconducting magnets to confine plasma within reactors, which in turn depend on advanced structural materials capable of withstanding extreme cryogenic environments, high magnetic...

  5. 520. M3Or4B-05: [Invited] Advancing Cryogenic Material Testing for High-Field Superconducting Magnets
    Oscar Sacristan De Frutos (CERN)
    21/05/2025, 17:50
    Invited Oral

    High-field superconducting magnets rely on precise knowledge of material properties at cryogenic temperatures to optimize performance and ensure long-term reliability. However, essential datasets —particularly for transport properties, thermal contraction, and mechanical behaviour— are often incomplete or entirely lacking. In this talk, we present recent results from cryogenic material...
