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…

Operation above the Greenwald density limit in high performance DIII-D negative triangularity discharges
O Sauter, R. Hong, A. Marinoni +9
The density limit in strongly-shaped negative triangularity (NT) discharges is studied experimentally in the DIII-D tokamak. Record-high Greenwald fractions are obtained, usi…
