Electromagnetic turbulent structures: A ubiquitous feature of the edge region of toroidal plasma configurations

Ambrogio Fasoli, Ivo Furno, Christian Gabriel Theiler, Fabio Avino, Nicola Vianello

Electromagnetic features of turbulent filaments, emerging from a turbulent plasma background, have been studied in four different magnetic configurations: the stellarator TJ-II, the Reversed Field Pinch RFX-mod, a device that can be operated also as a ohmi ...

Comparative studies of electrostatic turbulence induced transport in presence of resonant magnetic perturbations in RFX-mod

Nicola Vianello

Three-dimensional non-axisymmetric magnetic fields are purposely applied to toroidally symmetric fusion plasmas in order to modify transport of heat and particle fluxes to the plasma-facing components (PFCs), and specifically to control and suppress edge l ...

Density limit studies in the tokamak and the reversed-field pinch

Cristian Galperti, Nicola Vianello

The ITER scenarios and the project of DEMO involve stable operation above the Greenwald density, which justifies efforts to understand and overcome the density limit, this last observed as a disruptive termination of tokamak discharges and a thermal crash ...

Basic investigations of electrostatic turbulence and its interaction with plasma and suprathermal ions in a simple magnetized toroidal plasma

Ambrogio Fasoli, Ivo Furno, Sébastien Jolliet, Alexandre Dominique Bovet, Joaquim Loizu Cisquella, Paolo Ricci, Christian Gabriel Theiler, Fabio Riva, Kyle Gustafson, Fabio Avino, Nicola Vianello

Progress in basic understanding of turbulence and its influence on the transport both of the plasma bulk and of suprathermal components is achieved in the TORPEX simple magnetized torus. This configuration combines a microwave plasma production scheme with ...

Overview of the RFX-mod fusion science programme

Wilfred Anthony Cooper, Ambrogio Fasoli, Ivo Furno, Christian Gabriel Theiler, Fabio Avino, Elena Gaio, Nicola Vianello, Alberto Ferro

This paper reports the highlights of the RFX-mod fusion science programme since the last 2010 IAEA Fusion Energy Conference. The RFX-mod fusion science programme focused on two main goals: exploring the fusion potential of the reversed field pinch (RFP) ma ...

Blob current structures in TORPEX plasmas: experimental measurements and numerical simulations

Ambrogio Fasoli, Ivo Furno, Davoud Iraji, Paolo Ricci, Christian Gabriel Theiler, Diane Virginie Marie Lançon, Nicola Vianello

In the simple magnetized torus TORPEX, field-aligned blobs originate from ideal interchange waves and propagate radially outward due to del B and curvature induced drifts. Time-resolved two-dimensional measurements of the field-aligned current density J(pa ...

Overview of the RFX fusion science program

Wilfred Anthony Cooper, Elena Gaio, Nicola Vianello, Alberto Ferro, Zheng Wang

This paper summarizes the main achievements of the RFX fusion science program in the period between the 2008 and 2010 IAEA Fusion Energy Conferences. RFX-mod is the largest reversed field pinch in the world, equipped with a system of 192 coils for active c ...
