Inward thermodiffusive particle pinch in electron internal transport barriers in TCV

Olivier Sauter, Stefano Coda, Timothy Goodman, Henri Weisen, Emiliano Fable, Costanza Zucca, Alexey Zabolotskiy

Electron internal transport barriers (eITBs) are obtained in TCV with different heating and current drive schemes. They are sustained in steady-state conditions for several energy confinement and current redistribution times. In these scenarios, the densit ...

A new method for the inversion of interferometry data using basis functions derived from singular value decomposition of local measurements in tokamak plasmas

Ivo Furno, Henri Weisen, Roland Behn, Emiliano Fable, Alexey Zabolotskiy

A novel method for inverting time-resolved line-integrated interferometric plasma density measurements is described. The method uses singular value decomposition of local density profiles from Thomson scattering measurements obtained at low sampling rates ...

Collisionality and shear dependences of density peaking in JET and extrapolation to ITER

Ivo Furno, Henri Weisen, Alexey Zabolotskiy

Results from an extensive database analysis of JET density profiles in stationary conditions show that the density peaking factor n(e0)/< n(e)> in JET H modes increases from near 1.2 at high collisionality to around 1.5 as the plasma collisionality decreas ...

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 ...

Particle transport in tokamak plasmas

Alexey Zabolotskiy

The transport of particles in magnetically confined plasmas is of great importance for the development of fusion energy. It will determine techniques for fuelling, for controlling impurity concentrations and for the removal of the alpha particles produced ...
