Poloidal and toroidal rotation has been recognized to play an important role in heat transport
and magnetohydrodynamic (MHD) stability in tokamaks and helical systems. It is well known …

Tokamaks have demonstrated excellent plasma confinement capability because of their
symmetry but has an intrinsic drawback because of their pulsed inductive operation. Efforts …

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 …

In this Letter, the influence of the “Coriolis drift” on small scale instabilities in toroidal
plasmas is shown to generate a toroidal momentum pinch velocity. Such a pinch results …

The impact of plasma shaping on electron heat transport is investigated in TCV L-mode
plasmas. The study is motivated by the observation of an increase in the energy confinement …

Toroidal momentum transport mechanisms are reviewed and put in a broader perspective.
The generation of a finite momentum flux is closely related to the breaking of symmetry …

The turbulent convective flux of the toroidal angular momentum density is derived using the
nonlinear toroidal gyrokinetic equation which conserves phase space density and energy …

In tokamaks, turbulent particle and toroidal momentum transport are both characterized by
the presence of off-diagonal contributions which play an essential role in establishing the …

Bulk plasma toroidal rotation is observed to invert spontaneously from counter to cocurrent
direction in TCV (Tokamak à Configuration Variable) Ohmically heated discharges, in low …

The symmetry of a physical system strongly impacts on its properties. In toroidal plasmas,
the symmetry along a magnetic field line usually constrains the radial flux of parallel …
