What’s New

The European Domestic Agency has developed a new numerical model that represents ITER's 18 toroidal field magnets with remarkable detail. The model will be used to compute the magnetic fields produced by the coils and the resulting electromagnetic forces on the magnet system, which are the result of the interaction between electrical currents and the magnetic field.

"It's the first time we have a complete model of the entire ITER toroidal field system to such a level of detail," says Gabriele D'Amico, the technical support officer responsible for the development of the model. "The level of complexity of the tool is outstanding. For example there are more than 1,500 bolts connecting the different pieces of the toroidal field magnet system, and the model allows us to predict the behaviour of each one during operations."

The model, which took six months to develop, will allow the European Domestic Agency and the ITER Organization to simulate different scenarios using an approach that integrates the 18 coils and all major subsystems. Scientists will be able to study the occurrence of an electrical fault during operation, for example, or the impact of possible misalignment in the assembly of the coils on the behaviour of the whole system.
