A giant, slow-motion game of musical chairs

One component leaves sector sub-assembly tooling, another arrives ... the intricately coordinated transfers of large components in the ITER Assembly Hall resemble a slow-moving game of musical chairs.

Reaching target position is a 5-day operation

Each of the nine sector modules that form ITER’s plasma chamber is approximately 13 metres tall and, once rid of its lifting rig, weighs in excess of 1,200 tonnes. In terms of height, this is the equivalent of a five...

How ITER quantifies fusion power

To prove fusion ’ s promise, ITER must not only create energy—it must also measure it with great precision.

Release of IMAS infrastructure and physics models as open source

In another step to support global efforts to develop fusion energy, the ITER Organization is releasing the tools it uses for physics modelling and analysis—the ITER Integrated Modelling & Analysis Suite, IMAS—under open...
