Applications of a novel model-based real-time observer for electron density profile control experiments in TCV
F. Pastore, O. Sauter, F. Felici +12
Real-time control of tokamak plasmas encompasses sustaining a high-performance stationary state, avoiding disruptions, and managing ramp-up and ramp-down phases. Real-time estimati…
On the interplay between plasma triangularity and micro-tearing turbulence
Alessandro Balestri, Justin Ball, Stefano Coda
In this work, we study the interplay between triangularity and micro-tearing turbulence using linear and nonlinear flux tube GENE simulations. We consider scenarios with negative a…
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…
Physics of the low momentum diffusivity regime in tokamaks and its experimental applicability
Haomin Sun, Justin Ball, Stephan Brunner +9
Strong plasma flow shear is beneficial for reducing turbulent transport. However, traditional methods of driving flow shear do not scale well to large devices such as f…
