The benefit achieved by industry in its co-operation with the fusion laboratories is twofold. The direct advantage is due to the know-how accumulated on the topic while working together with fusion experts, both physicists and engineers. This has allowed industry to increase its knowledge in all critical aspects linked to the design of fusion device components. The second, indirect, benefit originates from the spin-offs, which inevitably derive from working in a high-technology environment. New materials, techniques and procedures, developed while working on fusion, have been used also for solving problems in other areas and have had a positive influence in the development of other kinds of components and products. Examples include advances in superconducting technology, fabrication processes, and measurement techniques.
