The L-H transition in tokamaks: power threshold, density minimum and toroidal-field asymmetry
Brenno De Lucca, Paolo Ricci, Benoit Labit +3
The physical mechanism underlying the L--H transition in tokamaks has remained an open problem for over forty years. We present three-dimensional flux-driven two-fluid simulations…
The physics of ELM-free regimes in EUROfusion tokamaks
M. G. Dunne, M. Faitsch, O. Sauter +25
The development of operational scenarios without large Type-I ELMs is of utmost importance for the stable operation and longevity of future tokamaks. The EUROfusion tokamak exploit…
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…
