Electron heat transport dependence on plasma shape and collisionality in EC heated L-mode TCV plasmas

Roland Behn, Timothy Goodman, Jean-Marc Moret, Antoine Pochelon, Olivier Sauter, Stefano Coda, Alberto Bottino, Laurie Porte, Yann Camenen, Ilya Pavlov

2005

A new method for the inversion of interferometry data using basis functions derived from singular value decomposition of local measurements in tokamak plasmas

Roland Behn, Henri Weisen, Ivo Furno, Alexey Zabolotskiy, Emiliano Fable

A novel method for inverting time-resolved line-integrated interferometric plasma density measurements is described. The method uses singular value decomposition of local density profiles from Thomson scattering measurements obtained at low sampling rates ...

Electron heat transport in shaped TCV L-mode plasmas

Roland Behn, Timothy Goodman, Antoine Pochelon, Olivier Sauter, Stefano Coda, Alberto Bottino, Alexander Karpushov, Laurie Porte, Yann Camenen

Electron heat transport experiments are performed in L-mode discharges at various plasma triangularities, using radially localized electron cyclotron heating to vary independently both the electron temperature T-e and the normalized electron temperature gr ...

High-bootstrap, noninductively sustained electron internal transport barriers in the Tokamak a Configuration Variable

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

Important ingredients of the advanced-tokamak route to fusion have been explored in depth in the Tokamak a Configuration Variable [F. Hofmann, J. B. Lister, M. Anton , Plasma Phys. Controlled Fusion 36, B277 (1994)] over the past two years. Using a uniquel ...

On the Tokamak a Configuration Variable (TCV), electron internal transport barriers (eITBs) can be formed during a gradual evolution from a centrally peaked to a hollow current profile while all external actuators are held constant. The formation occurs ra ...
