Anisotropic pressure bi-Maxwellian distribution function model for three-dimensional equilibria

A formulation of the anisotropic pressure magnetohydrodynamic equilibrium problem for three-dimensional plasmas with imposed nested magnetic surfaces is developed based on a bi-Maxwellian model of the distribution function for the energetic particle specie ...

Kink instability of flux ropes anchored at one end and free at the other

Ivo Furno

The kink instability of a magnetized plasma column (flux rope) is a fundamental process observed in laboratory and in natural plasmas. Previous theoretical, experimental, and observational work has focused either on the case of periodic (infinite) ropes (r ...

A full-wave solver of the Maxwell's equations in 3D cold plasmas

Laurent Villard, Wilfred Anthony Cooper

A new solver for Maxwell's equations in three-dimensional (3D) plasma configurations is presented. The new code LEMan (Low-frequency ElectroMagnetic wave propagation) determines a global solution of the wave equation in a realistic stellarator geometry at ...

Interchange turbulence in the TCV scrape-off layer

Jonathan Graves, Richard Pitts, Jan Horacek

Probe measurements of electrostatic plasma fluctuations in the scrape-off layer (SOL) of the TCV tokamak are compared with the results from two-dimensional interchange turbulence simulations. Excellent agreement is found for both the radial variation of st ...

Studies of Electron Transport and Current Diffusion in Switched ECCD experiments on TCV

Olivier Sauter, Timothy Goodman, Stefano Alberti, Roland Behn, Emiliano Fable, Costanza Zucca

The aim of the present work is to provide a better insight on the magnetic shear profile modification in the Switched ECCD experiments. Modelling of the plasma current density is carried on by the ASTRA transport code employed in both predictive and interp ...

SOLPS5 modelling of ELMing H-mode on TCV

Barbora Bruant Gulejová, Richard Pitts, Jan Horacek, Roland Behn, Marco Wischmeier, János Márki

Although ohmic H-modes have long been produced on the TCV tokamak and the effects of ELMs at the divertor targets studied in some detail [1], no attempt has yet been made to model the scrape-off layer (SOL) in these plasmas. This contribution describes det ...

First results of correlation electron cyclotron emission on Tore Supra

Measurements of electron temperature fluctuations by means of correlation electron cyclotron emission (ECE) diagnostics aid in understanding the nature of the turbulent transport infusion plasmas. On Tore Supra tokamak, a 32-channel heterodyne ECE radiomet ...

Experimental characterization and modelling of the particle source in an Electron-Cyclotron wave driven toroidal plasma

Ambrogio Fasoli, Benoît Labit, Mario Ludovico Podesta, Francesca Maria Poli

The plasma particle source resulting from ionization by microwaves in the electron-cyclotron range of frequencies is investigated in the simple magnetized torus TORPEX ( Fasoli A et al 2006 Phys. Plasmas 13 055902), together with its dependence upon experi ...

Overview of TCV Results

Ambrogio Fasoli

The Tokamak `a Configuration Variable , TCV, addresses scientific questions to improve our understanding of magnetically confined plasmas and our ability to control them in ITER relevant scenarios, and explores avenues to improve the plasma performance on ...

Stability and toroidal rotation properties of highly shaped plasmas in the TCV tokamak

Andrea Scarabosio

Magnetohydrodynamic (MHD) instabilities and plasma rotation have various impacts on particle and thermal transport in toroidal plasmas. MHD instabilities degrade the confinement, limit the maximum achievable plasma pressure, and can lead to plasma disrupti ...
