To construct a machine capable of producing plasmas approaching those of a thermonuclear reactor it will be necessary to master techniques of controlling the plasma (supplying/extracting matter and heat). Only then will the operation resemble that of a real reactor. The Tore Supra tokamak in Cadarache is equipped with superconducting toroidal coils and with a system for continuous cooling of the vacuum chamber by means of a circuit of pressurised water. This makes it possible to develop a number of systems necessary for plasma control: - the extraction and injection of matter, by combined use of "mistaken" divertors and an "ice-pellet" injector; - current generation; - control of the plasma-wall interaction; - ergodic divertor. Parallel to the development of this large-scale equipment, numerous experiments in plasma physics have been carried out, such as: experiments into the interaction of decoupled electrons with the toroidal magnetic field; thermal instabilities; current profile/MHD interaction.
