Investigation of the impact of ETGs on electron heat transport in TCV plasmas with NBI and ECH injection

In the most important future fusion devices, like ITER, the core temperature and fusion performance will strongly depend on electron heat transport, which is dominated by turbulent processes. Electron Temperature Gradient (ETG) micro-turbulence modes have been recently shown to impact the electron heat transport in tokamaks in conditions when ion-scale turbulence is close to marginality and electron heating is significant.
