First measurements of oblique ECE with a real-time moveable line-of-sight on TCV

Olivier Sauter, Timothy Goodman, Christian Schlatter, Igor Klimanov

Electron cyclotron (EC) emission (ECE) radiometers viewing perpendicular to the magnetic field are common on nearly all tokamaks for measuring the electron temperature with good spatio-temporal resolution. Two such radiometers are installed on TCV, one loo ...

Generation of suprathermal electrons during sawtooth crashes in a tokamak plasma

Ambrogio Fasoli, Timothy Goodman, Igor Klimanov

The acceleration of electrons during a sawtooth crash is demonstrated in various regimes of the TCV tokamak plasma. Simultaneous measurements of electron cyclotron emission from the low field side and from the high field side of the tokamak provide informa ...

Electron Bernstein wave heating of over-dense H-mode plasmas in the TCV tokamak via O-X-B double mode conversion

Basil Duval, Stefano Coda, Timothy Goodman, Yves Martin, Jean-Marc Moret, Laurie Porte, Antoine Pochelon, Yann Camenen, Igor Klimanov, Loïc Curchod

This paper reports on the first demonstration of electron Bernsteinwave heating (EBWH) by double mode conversion from ordinary (O-) to Bernstein (B-) via the extraordinary (X-) mode in an over-dense tokamak plasma, using low field side launch, achieved in ...

Recent electron cyclotron emission results on TCV

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Patrick Blanchard, Laurie Porte, Xavier Llobet, Christian Schlatter, Henri Weisen, Emiliano Fable

Electron cyclotron emission (ECE) diagnostics on Tokamak a Configuration Variable (TCV) allow study of the electron temperature evolution in time with good spatial and temporal resolution at the high field side and low field side at various lines of sight. ...

The effect of ECRH on the electron velocity distribution function

Ambrogio Fasoli, Stefano Coda, Stefano Alberti, Patrick Blanchard, Gilles Arnoux, Igor Klimanov

Electron cyclotron resonance heating (ECRH) is a mature technology that has progressed constantly over a period of forty years, particularly as a tool in magnetic confinement fusion. As with other heating methods, this technique has seen a steady increase ...

Reconstruction of the electron distribution function during ECRH/ECCD and magnetic reconnection events in a tokamak plasma

Igor Klimanov

The performance of tokamaks is usually described in terms of plasma temperature, density and confinement time. The term temperature implies that the plasma is in thermal equilibrium and its particles have maxwellian (normal) velocity distribution. However, ...
