Spontaneous L-mode plasma rotation scaling in the TCV tokamak

Olivier Sauter, Basil Duval, Alexander Karpushov, Richard Pitts, Antoine Pochelon, Andrea Scarabosio, Alessandro Bortolon

2008

Inter-machine comparison of intrinsic toroidal rotation in tokamaks

Basil Duval, Antoine Pochelon, Andrea Scarabosio, Alessandro Bortolon

Parametric scalings of the intrinsic (spontaneous, with no external momentum input) toroidal rotation observed on a large number of tokamaks have been combined with an eye towards revealing the underlying mechanism(s) and extrapolation to future devices. T ...

Bulk Plasma Rotation in the TCV Tokamak in the Absence of External Momentum Input (Invited paper)

Basil Duval, Alexander Karpushov, Richard Pitts, Antoine Pochelon, Andrea Scarabosio, Alessandro Bortolon

2007

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

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

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 ...

Plasma shape stabilization of current rise MHD instabilities in TCV

Yves Martin, Antoine Pochelon, Andrea Scarabosio

The well-known and potentially disruptive plasma 'current rise' instabilities are studied as a function of the plasma shape in the Tokamak a a Configuration Variable (TCV). Disruptions typically occur in quasi-circular plasmas at q(a) - 3 in both non-sawto ...

Bulk Plasma Rotation in the TCV Tokamak in the Absence of External Momentum Input

Basil Duval, Alexander Karpushov, Richard Pitts, Antoine Pochelon, Andrea Scarabosio, Alessandro Bortolon

2007

Current profile tailoring using localized electron cyclotron heating in highly elongated TCV plasmas

Olivier Sauter, Stefano Coda, Timothy Goodman, Stefano Alberti, Patrick Blanchard, Laurie Porte, Antoine Pochelon, Yann Camenen, Andrea Scarabosio, Gilles Arnoux

Radially localized electron cyclotron heating (ECH) at the 2nd harmonic (X2) is used to tailor the current profile through the modification of the temperature, and hence conductivity, profiles. The optimal conditions for current profile broadening are inve ...
