A new paradigm is presented to reconstruct the plasma current density profile in a tokamak
in real-time. The traditional method of basing the reconstruction on real-time diagnostics …

For stellarators, which need no or only small amounts of current drive, electron-cyclotron-
resonance heating (ECRH) is a promising heating method even for the envisaged …

The role played by electron density fluctuations near the plasma edge on rf current drive in
tokamaks is assessed quantitatively. For this purpose, a general framework for incorporating …

The toroidal current has been rapidly ramped-up after the formation of an initial closed flux
surface in an electron cyclotron heated discharge in the low aspect ratio torus experiment …

High-power millimeter wave sources are a key enabling technology in fusion energy
research. The present state of the art of application of these sources to the areas of heating …

Recent investigations of electron cyclotron current drive (ECCD) in tokamaks and
stellarators are the subject of this paper. Values of ECCD efficiency achieved in different …

Electron cyclotron current drive (ECCD) is an important prospective tool for tailoring the
current profile in next-step devices. To fill the remaining gaps between ECCD theory and …

Stable, high-performance operation of a tokamak requires several plasma control problems
to be handled simultaneously. Moreover, the complex physics which governs the tokamak …

Abstract The Tokamak à Configuration Variable (TCV) tokamak (R= 0.88 m, a< 0.25 m, B<
1.54 T) programme is based on flexible plasma shaping and heating for studies of …

With the very high electron cyclotron (EC) wave power density achieved in the TCV tokamak,
more than 20 MW m− 3, quasilinear modelling predicts an electron cyclotron current drive …
