Magnetic Equilibrium Reconstruction Techniques for Tokamak Reactors
The successful operation and performance of both present-day experimental tokamaks and future tokamak reactors, such as ITER, relies heavily upon an accurate determination of plasma position, shape and energy content, and on other global and local equilibrium quantities. Part of this information is required on a real-time basis to allow control of the discharge and possibly, in a reactor, on-line improvements of performances. For in-depth scientific analysis of the results and comparison with theory, however, it is also necessary to perform, both as snapshots and as historic time-evolution, off-line equilibrium reconstructions from the available measurements. As a rule, this is required with high space- and time-resolution and high accuracy.
