The poloidal field circuit in the Joint European Torus /JET/
Abstract
Some aspects of the circuit that produces the plasma (3.8 to 4.8 MA) in the Joint European Torus (JET) and maintains it in equilibrium are described. It is noted that the flux from the JET transformer is driven almost equally in both directions and that the main power source for the 3.8-MA plasma is a generator-rectifier set rated at 70 kA, 4.5 kV dc, and 600 MJ energy. An additional thyristor bridge fed by a network is also employed for the 4.8-MA plasma. All active coils are connected in parallel, passive coils may be used to produce forces that counteract fast plasma motions, and four thyristor bridges (13 kA, 1 kV) are employed to control voltages and currents in the coils as well as to provide stability of the plasma position.
