A Splittable CS Model Coil for ITER

The purpose of the Splittable CS Model Coil is twofold: to test the different conductors proposed for ITER in relevant conditions and to check the manufacturing processes foreseen for the ITER magnets. This model coil consists of a main coil in the shape of a circular solenoid and a single-layer removable insert. An inflatable steel jacket set between the main coil and the insert and a precompression system allows the insert to be put into compression at a stress level comparable to the one projected in the ITER Central Solenoid (CS) when it is used as a central bucking post for the toroidal magnet. The experimentation performed with this CS Model Coil will assess the dependence of the critical current on the imposed external compressive or tensile stress.<
