Edge localized modes in DIII-D high performance discharges

A new understanding of edge localized modes (ELMs) in tokamak discharges is emerging (Snyder P B et al 2002 Phys. Plasmas 9 2037), in which the ELM is an essentially ideal magnetohydrodynamic (MHD) instability and the ELM severity is determined by the radi ...

ELM moderation with ICRF heating on JET

Olivier Sauter

A high-density, ELM-free, 'enhanced Dalpha' (EDA) H-mode has been demonstrated with Ohmic or RF heating on the Alcator C-Mod device. An allied 'low particle confinement' H-regime was also observed previously in 'Mk0' divertor experiments on JET. Initial at ...

Effect on confinement of edge-localized modes in TCV

Yves Martin, Jean-Marc Moret, Henri Weisen, Richard Pitts, Antoine Pochelon

The effect of ELMs on confinement in ohmic H-modes has been investigated by analysing the rates of change of global parameters such as the electron content and the stored energy as a function of ELM frequency. In double-null H-modes, ELMs are found to expe ...

Ohmic H-modes in the TCV tokamak

Olivier Sauter, Basil Duval, Yves Martin, Jean-Marc Moret, Minh Quang Tran, René Chavan, Damien Fasel, Xavier Llobet, Pierre Lavanchy, Henri Weisen, Jonathan Bryan Lister, Richard Pitts, Antoine Pochelon, Roland Behn, Francis Troyon, Philippe Marmillod, Gilbert Tonetti, Albert Perez, Blaise Marlétaz, Pierre-François Isoz, Jean-Claude Magnin

The TCV tokamak has obtained ohmic H-modes in virtually all diverted plasmas with the ion del B drift directed towards an X-point and in several elongated limiter plasmas. Troyon factors (beta(tor)aB/l(p)) up to 2 and line average densities up to 2.2 x 10( ...
