Winding of the superconducting coil, the largest component of the magnet windings, is well underway. The superconducting coil is wound with a cable-in-conduit conductor (CICC) that contains hundreds of Nb3Sn/Cu superconductor wires. The total length of CICC to be wound is 1.8 kilometers.
Four of 18 layers have been wound. The first three layers contained the largest “High-Field” CICC in the magnet. A complex structural link – a MagLab innovation – was successfully installed to connect the “High-Field CICC” of the third layer to the fourth layer, a layer that is the first in the winding of the smaller “Mid-Field CICC”.
After coil winding and installation of inter-layer joints, the entire coil will go through a reaction heat treatment to form the superconductor, followed by epoxy impregnation and final assembly.
