Turbulent Origin of the Edge Radial Electric Field Asymmetry between Favourable and Unfavourable Drift Configurations
B. J. Frei, R. Bilato, W. Zholobenko +9
We study the influence of the ion magnetic-drift direction relative to the active X-point (favourable and unfavourable configurations) on edge turbulence, transport, and the radial…
Impact of magnetic drift configuration on the edge radial electric field in the TCV tokamak
S. Rienäcker, L. Vermare, P. Hennequin +8
The edge radial electric () in the Tokamak à Configuration Variable (TCV) is compared in matched L-mode discharges with opposite ion magnetic drift directions (favorable versu…
Two-length spatial correlation function of turbulence in TCV
Olivier Panico, Pascale Hennequin, Sascha Rienäcker +4
Spatial correlation functions of density fluctuations are measured in the Tokamak à Configuration Variable (TCV) using a dual-channel Doppler backscattering (DBS) diagnostic. In ce…
Edge Radial Electric Field in Positive and Negative Triangularity Plasmas in the TCV Tokamak
S. Rienäcker, P. Hennequin, L. Vermare +10
We present the first edge measurements in negative triangularity (NT) TCV plasmas. The Doppler backscattering measurements of reveal a significant imp…
Survey of the Edge Radial Electric Field in L-mode TCV Plasmas using Doppler Backscattering
Sascha Rienäcker, Pascale Hennequin, Laure Vermare +7
A Doppler backscattering (DBS) diagnostic has recently been installed on the Tokamak à Configuration Variable (TCV) to facilitate the study of edge turbulence and flow shear in a v…
Geodesic acoustic modes with poloidal mode couplings ad infinitum
Rameswar Singh, Ö D Gürcan, X Garbet +4
Geodesic acoustic modes (GAMs) are studied, for the first time, including all poloidal mode couplings using drift reduced fluid equations. The nearest neighbor coupling patte…
Geodesic acoustic modes in a fluid model of tokamak plasma : the effects of finite beta and collisionality
Rameswar Singh, A Storelli, Ozgur D Gurcan +4
Starting from the Braginskii equations, relevant for the tokamak edge region, a complete set of nonlinear equations for the geodesic acoustic modes (GAM) has been derived which inc…
Angular momentum transport modeling: achievements of a gyrokinetic quasi-linear approach
P. Cottier, C. Bourdelle, Y. Camenen +5
QuaLiKiz, a model based on a local gyrokinetic eigenvalue solver is expanded to include momentum flux modeling in addition to heat and particle fluxes. Essential for accurate momen…
