The Negative Triangularity Tokamak Path for Fusion Pilot Plants: Experimental Progress and Future Prospects
K. E. Thome, M. E. Austin, S. Coda +8
This paper reviews the experimental progress of negative triangularity (NT), a tokamak configuration where the poloidal cross-section is a reversed-D shape compared to the conventi…
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…
An upper pressure limit for low-Z benign termination of runaway electron beams in TCV
M Hoppe, J Decker, U Sheikh +17
We present a model for the particle balance in the post-disruption runaway electron plateau phase of a tokamak discharge. The model is constructed with the help of, and applied to,…
On the feasibility of Ohmically heated negative triangularity tokamak power plants
Alessandro Balestri, Justin Ball, Stefano Coda
Negative triangularity tokamak plasmas feature naturally enhanced confinement in the so-called L-mode regime, irrespective of the power of external heating. This is in contrast to…
Cross-Calibration and First Vertical ECE Measurement of Electron Energy Distribution in the TCV Tokamak
A. Tema Biwole, L. Porte, A. Fasoli +8
This paper describes the first Vertical Electron Cyclotron Emission (V-ECE) measurement of non-thermal electron distributions in the \textit{Tokamak à Configuration Variable}, TCV.…
Physical insights from the aspect ratio dependence of turbulence in negative triangularity plasmas
Alessandro Balestri, Justin Ball, Stefano Coda +3
In this work, we study the impact of aspect ratio A = R0 /r (the ratio of major radius R0 to minor radius r) on the confinement benefits of Negative Triangularity (NT) plasma shapi…
