The making of a ring coil—a photo story

R.A.

From one end to the other of the on-site manufacturing facility for poloidal field coils, the different production stations are now clearly delimited, with tooling in various stages of installation. In this 257-metre-long workshop, European contractors will carry out the winding, impregnation, and assembly phases for the four largest ring magnets, with diameters of 17 to 24 metres.

The dummy for PF Coil #5, with copper conductor instead of niobium-titanium alloy, is in the last stages of winding. (Click to view larger version...)
The dummy for PF Coil #5, with copper conductor instead of niobium-titanium alloy, is in the last stages of winding.
The process will require at least 18 months per coil. Series manufacturing for the "building blocks" of the coils, called double pancake windings, can begin as soon as qualification activities are validated. The first pre-dummy pancake—made with several turns of copper conductor instead of the real superconducting materials—has been wound and the manufacture of a full two-layer PF5 dummy double pancake is underway to qualify all processes.

Contractors are installing the later-phase tooling stations now. In the gallery below, you'll see progress made recently on the double pancake impregnation station in the centre of the facility and on the full coil impregnation station at the far end.
