Threshold power for the transition into H-mode for H, D, and He plasmas in TCV

Roland Behn, Basil Duval, Yves Martin, Alexander Karpushov, Laurie Porte, Benoît Labit

The threshold power for the transition into H-mode with hydrogen (H), deuterium (D), and helium (He) as majority ion species has been evaluated from a series of dedicated experiments on the tokamak TCV. Identical plasma configurations with a single-null X- ...

High density experiments in TCV ohmically heated and L-mode plasmas

Roland Behn, Basil Duval, Timothy Goodman, Antoine Pochelon, Olivier Sauter, Stefano Coda, Alexander Karpushov, Laurie Porte, Benoît Labit

Recent experiments have been performed on the Tokamak a configuration variable (TCV) to investigate the confinement properties of high density plasmas and the mechanism behind the density limit. In a limiter configuration with plasma elongation kappa = 1.3 ...

On the non-stiffness of edge transport in L-mode tokamak plasmas

Stephan Brunner, Roland Behn, Basil Duval, Timothy Goodman, Olivier Sauter, Stefano Coda, Alexander Karpushov, Yann Camenen, Lucia Isabel Federspiel, Doohyun Kim, Gabriele Merlo, Antoine Pierre Emmanuel Alexis Merle, Donghyun Kim

Transport analyses using first-principle turbulence codes and 11/2-D transport codes usually study radial transport properties between the tokamak plasma magnetic axis and a normalized minor radius around 0.8. In this region, heat transport shows significa ...

H-mode access during plasma current ramp-up in TCV

Roland Behn, Yves Martin, Ivo Furno, Holger Reimerdes, Benoît Labit

A recent TCV experiment has investigated the dependence of the L H transition threshold power on the plasma current ramp-rate and the X-point height above the divertor target, which both have previously been seen to affect the transition behaviour. Systema ...

Use of webcams as tools for alignment and supervision of a Thomson Scattering System in the near infrared

Roland Behn, Basil Duval, Pierre Etienne, Yanis Andrebe, Andreas Pitzschke

The alignment stability is a major concern for Thomson scattering systems. Even small angular deviations of the laser beams crossing the plasma lead to a loss of the calibration resulting in unreliable measurements of the electron density profile. For the ...

Impact of plasma triangularity and collisionality on electron heat transport in TCV L-mode plasmas

Roland Behn, Antoine Pochelon, Olivier Sauter, Stefano Coda, Alberto Bottino, Alexander Karpushov, Yann Camenen, Alessandro Bortolon

The impact of plasma shaping on electron heat transport is investigated in TCV L-mode plasmas. The study is motivated by the observation of an increase in the energy confinement time with decreasing plasma triangularity which may not be explained by a chan ...
