Inward thermodiffusive particle pinch in electron internal transport barriers in TCV

Timothy Goodman, Olivier Sauter, Henri Weisen, Stefano Coda, Alexey Zabolotskiy, Emiliano Fable, Costanza Zucca

Electron internal transport barriers (eITBs) are obtained in TCV with different heating and current drive schemes. They are sustained in steady-state conditions for several energy confinement and current redistribution times. In these scenarios, the densit ...

The stability of the ideal internal kink mode in realistic tokamak geometry

Olivier Sauter, Andrei Martynov, Jonathan Graves

The ideal stability of the internal kink mode is analysed for realistic tokamak geometry. Accurate numerical results demonstrate convergence with Bussac's toroidal solution (Bussac M N, Pellat R Edery D and Soule J L 1975 Phys. Rev. Lett. 35 1638) for inve ...

Influence of non-Maxwellian velocity distributions during ECRH and ECCD on electron temperature measurements by Thomson scattering

Roland Behn, Olivier Sauter, Petri Nikkola, Igor Klimanov

Deposition of electron cyclotron waves at high-power densities for heating and current drive in a tokamak plasma generates a population of fast electrons and therefore the velocity distribution of the electron population will deviate from a Maxwellian. Apa ...

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

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

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 ...

Fine-scale structures and negative-density regions: Comparison of numerical methods for solving the advection equation

Olivier Sauter, Laurent Villard

A common feature of the Vlasov equation is that it develops fine-scale filamentation as time evolves, as observed, for example, in global nonlinear simulations of the ion-temperature-gradient instability. From a numerical point of view, it is not trivial t ...
