Scale-Up of Silver–Copper Composite Wires by Spark Plasma Sintering and Room Temperature Wire-Drawing for Use in 100 T Triple Coil at LNCMI
Year: 2024
Type: article
Abstract: The generation of non-destructive pulsed magnetic fields of 100 T involves high mechanical stress, due to the Lorentz forces, sustainable by few conductors. At LNCMI, in the inner coil (the most mechanically stressed) of the 100 T triple coil system a Cu-Nb commercial conductor is used. This work explains firstly how a new bi-material design of the inner coil allows to reduce the quantity of the Cu-Nb wire used. Secondly, in order to replace this commercial Cu-Nb wire, the way to increase the volume of Ag-Cu composite conductors produced at CIRIMAT and LNCMI by powder metallurgy, Spark Plasma Sintering and wire drawing at room temperature is discussed.
