Completion of the ITER CS model coil - Outer module fabrication

The fabrication of the outer module has been completed, which is one of the Central Solenoid (CS) model coils being developed as the most important R&D for ITER construction. The inner and outer diameters are 2.8 m and 3.6 m, respectively. The weight is 63 tons. The conductor is a Nb3Sn cable-in-conduit conductor with a square Incoloy 908 conduit. The coil that consists of 8 layers was fabricated with a solenoid winding with two conductors-in-hand. The outer module will be connected with the inner module coil in series and contribute to the generation of 13 T at 46 kA. The test will be started in November 1999.
