Electron Bernstein Wave Heating and Emission in the TCV Tokamak

Timothy Goodman, Antoine Pochelon, Stefano Coda, Laurie Porte, Loïc Curchod, Yann Camenen

Electron cyclotron resonance heating (ECRH) of high-density tokamak plasmas is limited because of reflections of the waves at so-called wave cutoffs. Electron Bernstein wave (EBW) heating (EBWH) via a double mode conversion process from ordinary (O)-mode, ...

Impact of plasma triangularity and collisionality on electron heat transport in TCV L-mode plasmas

Roland Behn, Antoine Pochelon, Olivier Sauter, Stefano Coda, Alberto Bottino, Alexander Karpushov, Yann Camenen, Alessandro Bortolon

The impact of plasma shaping on electron heat transport is investigated in TCV L-mode plasmas. The study is motivated by the observation of an increase in the energy confinement time with decreasing plasma triangularity which may not be explained by a chan ...

Current profile tailoring using localized electron cyclotron heating in highly elongated TCV plasmas

Gilles Arnoux, Patrick Blanchard, Stefano Alberti, Timothy Goodman, Antoine Pochelon, Olivier Sauter, Stefano Coda, Andrea Scarabosio, Laurie Porte, Yann Camenen

Radially localized electron cyclotron heating (ECH) at the 2nd harmonic (X2) is used to tailor the current profile through the modification of the temperature, and hence conductivity, profiles. The optimal conditions for current profile broadening are inve ...

On ion cyclotron current drive for sawtooth control

Olivier Sauter, Stefano Coda

Experiments using ion cyclotron current drive (ICCD) to control sawteeth are presented. In particular, discharges demonstrating shortening of fast ion induced long sawteeth reported in (Eriksson et al 2004 Phys. Rev. Lett. 92 235004) by ICCD have been anal ...
