Simultaneous access to high normalized current, pressure, density, and confinement in strongly-shaped diverted negative triangularity plasmas
C. Paz-Soldan, C. Chrystal, P. Lunia +12
Strongly-shaped diverted negative triangularity (NT) plasmas in the DIII-D tokamak demonstrate simultaneous access to high normalized current, pressure, density, and confinement. N…
Characterization of the ELM-free Negative Triangularity Edge on DIII-D
A. O. Nelson, L. Schmitz, T. Cote +18
Tokamak plasmas with strong negative triangularity (NT) shaping typically exhibit fundamentally different edge behavior than conventional L-mode or H-mode plasmas. Over the entire…
Non-dimensional confinement scaling in similar negative triangularity plasmas on the DIII-D and TCV tokamaks
A. Marinoni, C. Chrystal, S. Coda +25
Similarity experiments were performed on the DIII-D and TCV tokamaks to explore the scaling of energy confinement in negative triangularity plasmas using non-dimensional variables.…
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…
Achievement of highly radiating plasma in negative triangularity and effect of reactor-relevant seeded impurities on confinement and transport
L. Casali, D. Eldon, T. Odstrcil +10
The first achievement of highly radiating plasmas in negative triangularity is shown with an operational space featuring high core radiation at high Greenwald fraction obtained wit…
Disentangling Core and Edge Mechanisms of the Density Limit in DIII-D Negative Triangularity Plasmas
R. Hong, P. H. Diamond, O. Sauter +14
The density limit is investigated in the DIII-D negative triangularity (NT) plasmas which lack a standard H-mode edge. We find the limit may not be a singular disruptive boundary b…
