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 ...

Plasma dynamics with second and third-harmonic ECRH and access to quasi-stationary ELM-free H-mode on TCV

Gilles Arnoux, Patrick Blanchard, Stefano Alberti, Ambrogio Fasoli, Timothy Goodman, Yves Martin, Henri Weisen, Stefano Coda, Andrea Scarabosio, Laurie Porte, Alessandro Bortolon, Mikhail Maslov

Intense electron cyclotron resonance heating (ECRH) and electron cyclotron current drive (ECCD) are employed on the Tokamak a Configuration Variable (TCV) both in second- and third-harmonic X-mode (X2 and X3). The plasma behaviour under such conditions is ...

Characterization of the electron distribution function in an electron-cyclotron driven toroidal plasma

Ambrogio Fasoli, Ivo Furno, Mario Ludovico Podesta, Francesca Maria Poli, Benoît Labit

The local properties of the electron energy distribution function are investigated in the electron-cyclotron wave driven toroidal device TORPEX (Fasoli et al 2006 Phys. Plasmas 13 055902). The electron energy distribution function is measured by means of a ...

Development of electrostatic turbulence from drift-interchange instabilities in a toroidal plasma

Ambrogio Fasoli, Mario Ludovico Podesta, Francesca Maria Poli

Electrostatic instabilities develop on TORPEX (TORoidal Plasma EXperiment) [A. Fasoli et al., Phys. of Plasmas, 13, 55902 (2006)] in the bad curvature region and propagate consistently with the drift wave dispersion relation. The wave number and frequency ...

Antenna excitation of drift wave in a toroidal plasma

Ambrogio Fasoli, Ivo Furno, Stefan Müller, Mario Ludovico Podesta, Francesca Maria Poli, Benoît Labit, Paolo Ricci

In a magnetized toroidal plasma, an antenna tunable in vertical wave number is used to excite density perturbations. Coherent detection is performed by means of Langmuir probes to directly determine both the wave vector and the plasma response induced by t ...
