Abstract

Data obtained in the Madison Symmetric Torus reversed-field pinch with a soft X-ray diagnostic will be presented. They have been used to study transient transport events in this device. Fast thermal relaxation events are associated to bursts of magnetohydrodynamic fluctuations.

Abstract

Images obtained with soft X-ray tomography in the RFX reversed field pinch device are presented. They show that the plasma can be in two different regimes, characterized by a different degree of magnetic chaos. Evidence of a coherent helical structure emerging from the chaotic plasma core is shown. These images indicate the power of tomography, which allows the study of the dynamics of a Hamiltonian system like the magnetic field lines.
