Europe completes pre-compression rings
In the ITER machine, two sets of three pre-compression rings will be installed at the top and bottom of the toroidal field coil structures. Mounted around the "tips" of the structures, the high tensile strength of the rings "pushes back" against the against the forces exerted on the toroidal field coils during operation, relieving stress and fatigue. Four other pre-compression rings will serve as spares.
The completion of this procurement package has been celebrated by the European Domestic Agency and contractors alike. Read the full report here.
