Chapter 2: Plasma confinement and transport

The understanding and predictive capability of transport physics and plasma confinement is reviewed from the perspective of achieving reactor-scale burning plasmas in the ITER tokamak, for both core and edge plasma regions. Very considerable progress has b ...

The effect of ECRH on the electron velocity distribution function

Ambrogio Fasoli, Stefano Coda, Stefano Alberti, Patrick Blanchard, Gilles Arnoux, Igor Klimanov

Electron cyclotron resonance heating (ECRH) is a mature technology that has progressed constantly over a period of forty years, particularly as a tool in magnetic confinement fusion. As with other heating methods, this technique has seen a steady increase ...

Inductive current density perturbations to probe electron internal transport barriers in tokamaks

Olivier Sauter, Stefano Coda, Timothy Goodman, Roland Behn, Alberto Bottino, Emiliano Fable, Costanza Zucca, Andrei Martynov, Petri Nikkola

Improved electron energy confinement in tokamak plasmas, related to internal transport barriers, has been linked to nonmonotonic current density profiles. This is difficult to prove experimentally since usually the current profiles evolve continuously and ...

Effects of a vertical magnetic field on particle confinement in a magnetized plasma torus

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

The particle confinement in a magnetized plasma torus with superimposed vertical magnetic field is modeled and measured experimentally. The formation of an equilibrium characterized by a parallel plasma current canceling out the grad B and curvature drifts ...

On the dependence of energy confinement on elongation in single null divertor plasmas

Yves Martin, Jean-Marc Moret, Henri Weisen

An analysis of the effect of magnetic geometry on heat flux in a wide range of single null diverted discharge configurations with 1.5 < κ(95) < 2.2, 0.2 < δ(95) < 0.45 suggests that elongation is beneficial for confinement. If heat diffusivitie ...

Understanding of H mode pedestal characteristics using the multimachine pedestal database

Henri Weisen

With use of a multimachine pedestal database, essential issues for each regime of ELM types are investigated. They include (i) understanding and prediction of pedestal pressure during type I ELMs, a reference operation mode of a future tokamak reactor; (ii ...

Energy confinement and MHD activity in shaped TCV plasmas with localized electron cyclotron heating

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Yves Martin, Jean-Marc Moret, Stefano Alberti, Ivo Furno, Minh Quang Tran, Patrick Blanchard, Holger Reimerdes, Jean-Philippe Hogge, René Chavan, Damien Fasel, Xavier Llobet, 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, Andrei Martynov, Adriano Manini, Paolo Bosshard, Edgar Scavino

Confinement in TCV electron cyclotron heated discharges was studied as a function of plasma shape, i.e. as a function of elongation, 1.1 < kappa < 2.15, and triangularity, -0.65 less than or equal to delta less than or equal to 0.55. The electron energy co ...

EFFECT OF LOCALISED ELECTRON CYCLOTRON HEATING ON ENERGY CONFINEMENT AND MHD IN TCV

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Yves Martin, Jean-Marc Moret, Ivo Furno, Minh Quang Tran, Holger Reimerdes, Jean-Philippe Hogge, Xavier Llobet, Henri Weisen, Jonathan Bryan Lister, Antoine Pochelon, Roland Behn, Gilbert Tonetti, Andrei Martynov, Adriano Manini

Within the range of plasma shapes and plasma currents investigated, the electron confinement time, tau_Ee, increases with safety factor, density and negative triangularity similar to the Ohmic heating case. There is little dependence of tau_Ee on the heati ...
