- Tore Supra
Tore Supra is a French
tokamak that began operating after the discontinuation of TFR (Tokamak ofFontenay-aux-Roses ) and of Petula (inGrenoble ). Its name comes from the wordstorus and superconductor, as "Tore Supra" is the only one of the largest tokamaks to have superconducting toroidal magnets, allowing the creation of a strong permanent toroidalmagnetic field .Tore Supra is situated at the nuclear research center of
Cadarache ,Bouches-du-Rhône , one of the sites of theCommissariat à l'Énergie Atomique . It started operation in1988 . It has a goal of creating long-duration plasma; it now holds the record of the longest plasma duration time for a tokamak (6 minutes 30 seconds and over 1000 MJ of energy injected and extracted in2003 ), and it allows to test critical parts of equipment such as plasma facing wall components or superconducting magnets that will be used in its successor,ITER .Device parameters
