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 ...
