Basic Investigation of Turbulent Structures and Blobs of Relevance for Magnetic Fusion Plasmas

Similarly to neutral fluids, plasmas often exhibit turbulent behavior. Turbulence in plasmas is usually more complex than in neutral fluids due to long range interactions via electric and magnetic fields, and kinetic effects. It gives rise to many interest ...

Convective cells and blob control in a simple magnetized torus

Ambrogio Fasoli, Ivo Furno, Christian Gabriel Theiler, Joaquim Loizu Cisquella

In view of controlling wall and divertor heat loads in magnetic fusion devices, we investigate the possibility of creating convective cells by means of biased electrodes for turbulence and blob control in the simple magnetized toroidal plasmas of TORPEX. A ...

Global two-fluid simulations of tokamak SOL turbulence

Paolo Ricci, Federico David Halpern, Annamaria Mosetto

We present non-linear self-consistent global simulations of the SOL plasma dynamics using the Global Braginskii Solver (GBS) code. The code solves on the drift-reduced Braginkii equations, with cold ions. Studied originally for the simulation of the Simple ...

Turbulence and bias-induced flows in simple magnetized toroidal plasmas

Paolo Ricci, Bo Li

Turbulence and bias-induced flows in simple magnetized toroidal plasmas are explored with global three-dimensional fluid simulations, focusing on the parameters of the Helimak experiment. The simulations show that plasma turbulence and transport in the reg ...

Magnetic energy flows during the current quench and termination of disruptions with runaway current plateau formation in JET and implications for ITER

James Paley

The magnetic energy balance and magnetic energy flows for plasma disruptions in which runaway plateau plasmas are formed and terminated at JET has been analysed and compared with that of runaway-free disruptions. The analysis shows that the energy loss pro ...

Direct two-dimensional measurements of the eld-aligned current associated with plasma blobs

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

In simple magnetized toroidal plasmas, field-aligned blobs originate from ideal interchange waves and propagate radially outward under the effect of

A 3D approach to equilibrium, stability and transport studies in RFX-mod improved regimes

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

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 descri ...

Turbulence Phase Space in Simple Magnetized Toroidal Plasmas

Paolo Ricci

Plasma turbulence in a simple magnetized torus (SMT) is explored for the first time with three-dimensional global fluid simulations. Three turbulence regimes are described: an ideal interchange mode regime, a previously undiscovered resistive interchange m ...

Plasma rotation and momentum transport studies in the TCV tokamak based on charge exchange spectroscopy measurements

Alessandro Bortolon

Thermonuclear controlled fusion research is a highly active branch of plasma physics. The main goal is the production of energy from the fusion reaction of hydrogen isotope nuclei, the same reaction that powers stars. The most promising present approach ar ...

Plasma fluctuation studies in the TCV tokamak

Alessandro Marinoni

One of the most important issues for magnetic-confinement fusion research is the so-called anomalous transport across magnetic field lines, i.e. transport that is in excess of that caused by collisional processes. The need to reduce anomalous transport in ...
