Abstract

Magnetic coil signals are used to obtain the toroidal mode number spectrum of the sawtooth instability in a small-aspect-ratio tokamak. The excellent correlation between the edge (magnetic) displacement and the core displacement (soft X-ray tomography) demonstrates the validity of this approach and makes magnetic coil measurements an appropriate tool for studying the sawtooth instability global wavefunction.
