Overview of Enhanced D-alpha and Quasi Continuous Exhaust H-modes at DIII-D
N. Leuthold, Z. Li, M. Faitsch +19
We review the Enhanced D-alpha (EDA) and Quasi-continuous Exhaust (QCE) H-modes that have recently been achieved in the DIII-D tokamak. These scenarios are free of large type-I edg…
Demonstration of H-mode Error Field Identification in a Single Discharge via Island Healing
E. M. Bursch, A. Xie, J. L. Barr +15
Non-disruptive compass scan error field identification via island healing is demonstrated on KSTAR in a single H-mode discharge. This method can allow for up to a 75% reduction in…
Assessing the effect of error field penetration during plasma current ramp-up in the DIII-D tokamak
C. F. B. Zimmermann, E. M. Bursch, C. Paz-Soldan +4
This work provides evidence that established error field penetration threshold scalings remain applicable during plasma current ramp-up. In dedicated DIII-D experiments with impose…
Resonant Pitch-Angle Scattering Of Runaway-Electrons by Externally-launched Helicon Waves in the DIII-D Tokamak
Hari Choudhury, Jeffrey Lestz, Carlos Paz-Soldan +12
Resonant wave-particle interactions between externally launched helicon waves (also known as whistler waves) and runaway electrons (REs) have been demonstrated on the DIII-D tokama…
Compact Experimental Negative TriAngUlarity Reactor (CENTAUR): A design study for a compact, affordable breakeven tokamak
The CENTAUR Collaboration, Samuel W. Freiberger, Evan Bursch +33
This work presents the compact experimental negative triangularity reactor (CENTAUR), a low overnight cost, high-field tokamak, breakeven reactor design, achieving a predicted tota…
First Demonstration of Resonant Pitch-Angle Scattering of Relativistic Electrons by Externally-Launched Helicon Waves
H. Choudhury, A. Battey, C. Paz-Soldan +12
Helicon waves satisfying the normal wave-particle cyclotron resonance are observed to limit the growth and maximum energy of relativistic electrons (REs) in low-density Ohmic DIII-…
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…
Operational Space and Plasma Performance with an RMP-ELM Suppressed Edge
C. Paz-Soldan, S. Gu, N. Leuthold +14
The operational space and global performance of plasmas with edge-localized modes (ELMs) suppressed by resonant magnetic perturbations (RMPs) are surveyed by comparing AUG, DIII-D,…
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…
Robust avoidance of edge-localized modes alongside gradient formation in the negative triangularity tokamak edge
A. O. Nelson, L. Schmitz, C. Paz-Soldan +7
In a series of high performance diverted discharges on DIII-D, we demonstrate that strong negative triangularity (NT) shaping robustly suppresses all edge-localized mode (ELM) acti…
