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 ...
