Manufacture of the tf coils for TFTR

The toroidal field coils for the TFTR Project are relatively large circular coils wound with hollow copper conductor. Sections of conductor lengths are brazed together, insulated, then wound around a circular mandrel. The completed coil must fit into a machined metallic case making the configuration control of the insulated coil very important during winding. The approach to the winding of these coils, a brief description of some of the winding tooling, and methods employed to wind the TFTR TF coils are discussed here
