A 3D approach to equilibrium, stability and transport studies in RFX-mod improved regimes
The full three-dimensional (3D) approach is now becoming an important issue for all magnetic confinement configurations. It is a necessary condition for the stellarator but also the tokamak and the reversed field pinch (RFP) now cannot be completely described in an axisymmetric framework. For the RFP the observation of self-sustained helical configurations with improved plasma performances requ...
متن کاملThermal gradients of QSH states in RFX-mod
The Reversed Field Pinch (RFP) is a fusion-aimed, toroidal magnetic configuration characterized by the presence of several resonant tearing modes that contribute to the sustainment of the configuration itself. However, such modes make the magnetic field stochastic through the overlapping of their magnetic islands. The field stochasticity, and the entailed strong transport typically found in Mul...
متن کاملResistive Wall Mode Active Rotation in RFX-mod
The fundamental question of how the flow velocity of the background plasma can influence the motion of magneto-hydrodynamics instabilities and, in ultimate analysis, their stability is addressed. The growth of Resistive Wall Mode instabilities in toroidal confinement devices well represents one example of such a problem. In this paper we illustrate a new strategy that allowed, for the first tim...
متن کامل1 OV / 5 - 2 Ra Overview of RFX - mod results
With the exploration of the MA plasma current regime in up to 0.5 s long discharges, RFX-mod has opened new and very promising perspectives for the Reversed Field Pinch (RFP) magnetic configuration, and has made a significant progress in understanding and improving confinement and in controlling plasma stability. A big leap with respect to previous knowledge and expectations on RFP physics and ...
متن کاملExternally Induced Rotation of the Resistive Wall Modes in RFX-mod
Introduction During the last years, significant progress was made in the control of resistive wall modes (RWMs) in reversed field pinches (RFPs). It was demonstrated on several different devices that static current driven RWMs can be completely suppressed and controlled [1,2]. It is well known that also tokamak advanced scenarios suffer from RWM instabilities. The RWM in a tokamak is typically ...
