Influence of non-Maxwellian velocity distributions during ECRH and ECCD on electron temperature measurements by Thomson scattering

Olivier Sauter, Roland Behn, Igor Klimanov, Petri Nikkola

Deposition of electron cyclotron waves at high-power densities for heating and current drive in a tokamak plasma generates a population of fast electrons and therefore the velocity distribution of the electron population will deviate from a Maxwellian. Apa ...

Shear modulation experiments with ECCD on TCV

Timothy Goodman, Stefano Alberti, Roland Behn, Petri Nikkola

Anomalous electron transport is determined by turbulence, which in turn is affected by magnetic shear. A novel application of electron cyclotron current drive (ECCD), aiming at localized shear modulation, has been applied on the TCV tokamak for experiments ...

Safety factor profile requirements for electron ITB formation in TCV

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Timothy Goodman, Yves Martin, Jean-Marc Moret, Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge

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 ...
