SOLPS5 modelling of the type III ELMing H-mode on TCV

Roland Behn, Richard Pitts, Marco Wischmeier, Jan Horacek, János Márki, Barbora Bruant Gulejová

Although ohmic H-modes have long been produced on TCV and the effects of ELMs at the divertor target studied in some detail, no attempt has yet been made to model the scrape-off layer (SOL) in these plasmas. This paper describes details of the first such e ...

Studies of Electron Transport and Current Diffusion in Switched ECCD experiments on TCV

Stefano Alberti, Roland Behn, Timothy Goodman, Olivier Sauter, Emiliano Fable, Costanza Zucca

The aim of the present work is to provide a better insight on the magnetic shear profile modification in the Switched ECCD experiments. Modelling of the plasma current density is carried on by the ASTRA transport code employed in both predictive and interp ...

SOLPS5 modelling of ELMing H-mode on TCV

Roland Behn, Richard Pitts, Marco Wischmeier, Jan Horacek, János Márki, Barbora Bruant Gulejová

Although ohmic H-modes have long been produced on the TCV tokamak and the effects of ELMs at the divertor targets studied in some detail [1], no attempt has yet been made to model the scrape-off layer (SOL) in these plasmas. This contribution describes det ...

Shear modulation experiments with ECCD on TCV

Stefano Alberti, Roland Behn, Timothy Goodman, Petri Nikkola

Anomalous electron transport is determined by turbulence, which in turn is affected by magnetic shear. A novel application of electron cyclotron current drive (ECCD), aiming at localized shear modulation, has been applied on the TCV tokamak for experiments ...

10-channel far-infrared polarimeter for the tokamak configuration variable

Patrick Blanchard, Roland Behn, Henri Weisen

A new far-infrared polarimeter diagnostic for the tokamak a configuration variable (TCV) is under construction at CRPP. It uses two FIR lasers at 432.5 mu m, optically pumped by a 120 W continuous wave CO2 laser. The two FIR cavities will be detuned such t ...

Influence of ELMs on Edge Temperature and Density Profiles in TCV

Roland Behn, Yves Martin, Karin Schombourg

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 ...
