Helical core tokamak MHD equilibrium states

Olivier Sauter, Basil Duval, Stefano Coda, Jonathan Graves, Wilfred Anthony Cooper, Holger Reimerdes, Benoît Labit, Antoine Pochelon, Jonathan Rossel, Mattia Albergante

Bifurcated magnetohydrodynamic tokamak equilibrium states with axisymmetric or helical core structure are computed. When a peaked pressure profile is chosen, the helical core structures appear like the {em snakes} that are observed in the JET tokamak. They ...

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

Comparison of measured and simulated fast ion velocity distributions in the TEXTOR tokamak

Mattia Albergante, Otto Asunta

Here we demonstrate a comprehensive comparison of collective Thomson scattering (CTS) measurements with steady-state Monte Carlo simulations performed with the ASCOT and VENUS codes. The measurements were taken at a location on the magnetic axis as well as ...

Magnonic minibands in antidot lattices with large spin-wave propagation velocities

Dirk Grundler

Antidot lattices fabricated from permalloy thin films have been investigated by all-electrical spin-wave spectroscopy and Brillouin light scattering. Periodic arrays of 120-nm-diameter nanoholes have been prepared using focused ion beam etching. The period ...

Antiferroelectric–ferroelectric phase boundary enhances polarization extension in rhombohedral Pb(Zr,Ti)O3

Dragan Damjanovic, Anirban Ghosh

The main mechanism of properties enhancement in the morphotropic phase boundary region separating tetragonal and rhombohedral phases of Pb(Zr1-xTix)O-3 (PZT) is related to polarization rotation. It is shown here that in proximity of the morphotropic phase ...

RF current drive and plasma fluctuations

Stefano Coda, Joan Decker

The role played by electron density fluctuations near the plasma edge on rf current drive in tokamaks is assessed quantitatively. For this purpose, a general framework for incorporating density fluctuations in existing modelling tools has been developed. I ...

Self-Consistent ICRH Distribution Functions and Equilibria in Magnetically Confined Plasmas

Martin Jucker

The deployment of high power radio frequency waves in the ion cyclotron range (ICRF) constitutes an important operational facility in many plasma devices, including ITER. Any charged particle describes a helical motion around a given magnetic field line, t ...

Experimental demonstration of an up-down asymmetry effect on intrinsic rotation in the TCV tokamak

Olivier Sauter, Basil Duval, Alexander Karpushov, Yann Camenen, Alessandro Bortolon, Lucia Isabel Federspiel, Francesco Piras

A new mechanism has recently been proposed that generates a radial flux of parallel momentum in toroidal plasmas. Namely, by considering up-down asymmetric flux surfaces, the symmetry following the magnetic field can be broken and an additional contributio ...

Fast polarizers installation for ECRH and ECE in TCV

Timothy Goodman, Federico Alberto Alfredo Felici, Laurie Porte

We report on the installation of fast polarizers for ECRH injection and ECE diagnostics, in the TCV tokamak. The main goal is to change the polarization during a plasma shot and react to changing conditions such as: plasma current and position, ECRH inject ...

Global Nonlinear Electromagnetic Simulations of Tokamak Turbulence

Laurent Villard, Stephan Brunner, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Thibaut Vernay

The particle-in-cell code ORB5 is a global gyrokinetic turbulence simulation code in tokamak geometry. It has been developed at CRPP, Lausanne, Switzerland, with major contributions from IPP, Garching, Germany, and IPP, Greifswald, Germany, under a long-st ...
