Tokamak Magnetohydrodynamic Equilibrium States with Axisymmetric Boundary and a 3D Helical Core

Olivier Sauter, Laurent Villard, Jonathan Graves, Wilfred Anthony Cooper, Antoine Pochelon

Magnetohydrodynamic (MHD) equilibrium states with imposed axisymmetric boundary are computed in which a spontaneous bifurcation develops to produce an internal three-dimensional (3D) configuration with a helical structure in addition to the standard axisym ...

The effect of plasma triangularity on turbulent transport:modelling TCV experiments by linear and non linear gyrokinetic simulations

Olivier Sauter, Stefano Coda, Laurent Villard, Jonathan Graves, Stephan Brunner, Antoine Pochelon, Yann Camenen, Alessandro Marinoni, Xavier Lapillonne

The effect of plasma shape on confinement has been experimentally explored in the TCV tokamak revealing that the core electron heat transport is significantly reduced by a negative triangularity configuration, which could indicate a (partial) stabilization ...

Snowflake Divertor Plasmas on TCV

Olivier Sauter, Basil Duval, Stefano Coda, Jean-Marc Moret, Ivo Furno, Federico Alberto Alfredo Felici, Richard Pitts, Antoine Pochelon, Costanza Zucca, Francesco Piras

Starting from a standard single null X-point configuration, a second order null divertor (snowflake (SF)) has been successfully created on the Tokamak à Configuration Variable (TCV) tokamak. The magnetic properties of this innovative configuration have bee ...

Inter-machine comparison of intrinsic toroidal rotation in tokamaks

Basil Duval, Antoine Pochelon, Andrea Scarabosio, Alessandro Bortolon

Parametric scalings of the intrinsic (spontaneous, with no external momentum input) toroidal rotation observed on a large number of tokamaks have been combined with an eye towards revealing the underlying mechanism(s) and extrapolation to future devices. T ...

Demonstration of Electron-Bernstein-Wave Heating in a Tokamak via O-X-B Double-Mode Conversion

Laurie Porte, Antoine Pochelon, Yann Camenen, Loïc Curchod

The first demonstration of electron-Bernstein-wave heating by double-mode conversion from the O to the X mode in an overdense H-mode tokamak plasma has been achieved in the Tokamak a` Configuration Variable device. This technique overcomes the upper densit ...

Electron Bernstein wave heating of over-dense H-mode plasmas in the TCV tokamak via O-X-B double mode conversion

Basil Duval, Stefano Coda, Timothy Goodman, Yves Martin, Jean-Marc Moret, Laurie Porte, Antoine Pochelon, Yann Camenen, Igor Klimanov, Loïc Curchod

This paper reports on the first demonstration of electron Bernsteinwave heating (EBWH) by double mode conversion from ordinary (O-) to Bernstein (B-) via the extraordinary (X-) mode in an over-dense tokamak plasma, using low field side launch, achieved in ...
