Realising fusion energy is a big, long term undertaking – fusion scientists tend to think in decades, rather than years. The experiments are large and expensive, and often require the collaboration of several laboratories. In the late 1970s, the European fusion laboratories joined forces to build and operate the Joint European Torus JET, which still is one of the world’s largest fusion experiments.
In 1999, these Associates re-formalised their co-operation by signing an agreement to pool their resources, share costs and coordinate their research, both in the short term, and also beyond JET. Thus the European Fusion Development Agreement (EFDA) was formed.
