This involved application of a glass-fibre/Kapton/glass-fibre insulation layer to each of the core elements. The whole assembly was then bonded together with precise control of the bond line thickness.

The central core is made of 24 inner elements of toroidal field coils, which each needed to be insulated. This was achieved by applying a glass-fibre prepreg/Kapton/glass-fibre prepreg insulating layer to each of the core elements.
