    Advances in Nb3Sn Superconducting Accelerator Magnets

    Speaker: Helene Felice, CEA/SACLAY

    With the faraway goal of a 100 TeV new hadron-hadron collider, the ambition for very high field accelerator magnets has never been so broad. The technology choice between Low Temperature Superconductor (LTS) Nb3Sn and High Temperature Superconductors (HTS) for such a machine remains to be made and might lead to a hybrid solution. In all cases, the challenges are ahead of us: from superconducting material’s cost to its implementation.
    Nb3Sn will be used in HL-LHC in the 11-12 T range. Models and prototypes are leading the path toward a small series which demonstration remains to be done. Nb3Sn is indeed the most advanced technology but is a delicate material. Its sensitivity to strain makes it a challenging candidate for high field and therefore high stress main dipoles. For large scale production toward the next collider, important progress on industrialization must be made.
    We propose here to revisit the implementation of this material in accelerator magnets from the early days of the technology to the state of the art. Nb3Sn magnet technology progress on design, coil fabrication, magnet assembly, and test will be covered. We will try to assess the key challenges to be faced to provide reliable Nb3Sn magnets for the High Energy physics community.

    Nb3Sn magnet development at CEA Paris-Saclay

    Speaker: Etienne Rochepault, CEA/SACLAY

    Nb3Sn magnet development is a key challenge for future high energy colliders. As part of an international effort, CEA-Paris Saclay is developing Nb3Sn technology toward 16 T magnets. The activity is distributed along several axes. On a fundamental standpoint, some work is led to investigate and understand dimensional changes of Nb3Sn during heat treatment. In parallel, a development plan toward high field dipoles has been established. The first phase consists in the design and fabrication of a 11-12T range simplified dipole aiming at addressing all the technological challenges of the final 16 T demonstrators. Progress on these various activities will be exposed and discussed
