Abstract

TORE SUPRA is a large-size, high-field superconducting tokamak. It was completed in 1988 and is starting its experimental operation. The plasma-wall interaction programme will be mainly devoted to obtaining very long pulses: i.e. the control of impurity content, power and particle exhaust. The design of the first wall takes this into account. The inner wall is made of graphite tiles brazed on stainless steel tubes, the outer wall of stainless steel panels. Three graphite limiters and six ergodic divertor modules have already been installed. Each of these is water-cooled. Vessel pumping is achieved by means of three turbomolecular pumps providing 9000l/s H(2) pumping speed. A 250 C baking capability of the vessel is also available. First operations were devoted to conditioning and carbonizing the whole plasma chamber, with RG-discharges, allowing working in homogeneous conditions. The first tokamak discharges are studied for a better knowledge of plasma control and stability in this configuration.
