An IAEA Specialists Meeting on Tokamak Concept Innovations was held 13–17 January 1986 at the IAEA Headquarters in Vienna. The purpose of this meeting was to identify innovations that would significantly improve the prospects of tokamak development leading to an attractive end-product – a viable tokamak fusion reactor. Emphasis was placed upon innovations that would lead to substantial improvements in a tokamak reactor, even if they involved a radical departure from present thinking. For the most part, such innovations are not yet supported by the existing database.
