The ITER Central Solenoid (CS) will be one of the world's largest and most powerful pulsed superconducting electromagnet ever built; at an approximate weight of 1300 tons and a total height of 18 m consisting of a stack of six electrically independent 4.1 m diameter modules. In order to electrically connect the CS with the feeder busbars, 12 twin box joints are used to assure an efficient high current transfer while avoiding excessive AC losses. [...]

The Central Solenoid (CS), a key component of the ITER Magnet system, using a 45 kA Nb 3 Sn conductor, includes six identical coils, called modules, to form a solenoid, enclosed inside a structure providing vertical pre-compression and mechanical support. Procurement of the components of the ITER CS is the responsibility of US ITER, the US Domestic Agency (USDA), while the assembly of these components will be carried out by the ITER Organization (IO).

In the ITER Magnet System, ten thousand tonnes of superconducting Cable In Conduit Conductor (CICC) arecooled down by a forcedflow of supercritical helium, which is supplied from helium inlets. For the ITER CentralSolenoid (CS), consisting of six independent pancake wound modules, the He inlets consist of three overlappingholes covered by an oblong shaped boss, welded to the CS jacket through full penetration, multi-pass TungstenInert Gas (TIG) welding [...]

The ITER Magnet System will be the largest and most challenging integrated superconducting magnet systemever built. For the Central Solenoid (CS), cable–in–conduit - conductors (CICCs) of nearly one kilometre lengthare produced, but still, it will be necessary to connect several lengths together to wind the gigantic 110 tonnescoils.

The development of new generation superconducting magnets for fusion research, such as the ITER experiment, is largely based on coils wound from so-called “Cable-In-Conduit” Conductors (CICCs). CICCs consist of various types of stainless steel jackets, densely filled with compacted superconducting strands, which are cooled by supercritical helium. [...]
