Measurement of magnetic fields in toroidal systems
Abstract
The distribution of magnetic flux surfaces is an important factor affecting stability, power balance and electron trapping in toroidal systems. In tokamaks and reversed field pinches the internal magnetic structure is inadequately known and can be quite complex, particularly during periods of plasma instability. The history of attempted magnetic field measurements on these devices is outlined and an assessment is made of the various techniques used. Recent measurements using laser beam scattering on DITE are described in some detail. The projected application of magnetic field measurement techniques to larger facilities such as JET is briefly discussed.
