Convective transport by filamentary structures in scrape-off layer plasmas

Richard Pitts, Jan Horacek

2007

Radiation distributions in TCV

Richard Pitts, Marco Wischmeier, Jan Horacek, Barbora Bruant Gulejová

Total radiative powers measured by foil bolometer and AXUV camera systems are compared to SOLPS5 simulations in low and high density deuterium and helium diverted discharges on the TCV tokamak. For low density the match between simulation and measurements ...

Statistical properties of electrostatic turbulence in toroidal magnetized plasmas

Ambrogio Fasoli, Ivo Furno, Jan Horacek, Mario Ludovico Podesta, Francesca Maria Poli, Benoît Labit, Gennady Plyushchev, Davoud Iraji, Paolo Ricci, Christian Gabriel Theiler

A unique parabolic relation is observed to link skewness and kurtosis of density fluctuation signals, measured over the whole cross-section of the simple toroidal device TORPEX for a broad range of experimental conditions. This relationship is also valid f ...

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 ...

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 ...

Measurement of edge electrostatic turbulence in the TCV tokamak plasma boundary

Jan Horacek

Almost since the first density profile measurements were made in the scrape-off layer (SOL) of the early tokamaks, it has been recognized that the rate of particle transport perpendicular to magnetic surfaces exceeds that expected on the basis of classical ...

Interchange turbulence in the TCV scrape-off layer

Richard Pitts, Jan Horacek, Jonathan Graves

Probe measurements of electrostatic plasma fluctuations in the scrape-off layer (SOL) of the TCV tokamak are compared with the results from two-dimensional interchange turbulence simulations. Excellent agreement is found for both the radial variation of st ...

Self-similar density turbulence in the TCV tokamak scrape-off layer

Richard Pitts, Jan Horacek, Jonathan Graves

Plasma fluctuations in the scrape-off layer (SOL) of the TCV tokamak exhibit statistical properties which are universal across a broad range of discharge conditions. Electron density fluctuations, from just inside the magnetic separatrix to the plasma-wall ...
