PLASMA POSITION AND SHAPE CONTROL IN TORE-SUPRA MAGNETIC MEASUREMENTS AND CONTROL LOOP
The Tore-Supra Tokamak permits, owing to the toroidal superconducting coils and the poloidal field system performances to realize long discharges, up to 30 seconds and more, for a nominal plasma current of 1,7 MA. Longer discharges are foreseen with a lower plasma current value. The poloidal field system consists of nine poloidal field coils, each one connected to its own power supply and all assembled in parallel to form a conductive shell. During the whole plasma discharge these coils are used to control the plasma current value and the plasma boundary position. A feed-back loop system elaborates the nine voltage references for the power supplies. A special design of this system is necessary due to the long pulse operation and the nine free parameters to control. The magnetic field measurements and the real-time computers will be described.
