High strength conductors

The design and fabrication of non destructive high-field magnets represent a significant challenge for materials development and selection because the component has both a structural requirement (high tensile strength to sustain the Lorentz forces) and a functional requirement (low electrical resistivity to get the highest action integral). The LNCMP is involved in the development of two families of high strength conductors:

- macrocomposite conductors (copper core with a stainless steel jacket, UTS: 1 GPa) for conventional coils and for coils with optimized reinforcement distribution

- ultra-high strength nanofilamentary conductors (copper/niobium, copper/tantalum, UTS: 2 GPa) for Coilin/Coilex system (B>80T).

- Carbon nanotubes – copper composites

The wire-drawing workshop, located in the basement of the buiding, allows such in-house development.
