Impurity-driven turbulence opens a pathway to ELM-free operation and enhanced pedestal stability in tokamaks
Santanu Banerjee, T. Macwan, A. Bortolon +7
Edge-localized modes (ELMs) impose severe transient heat, and particle loads on plasma-facing components, posing a critical challenge for steady-state operation of tokamak fusion r…
Broadening of the Divertor Heat Flux Profile in High Confinement Tokamak Fusion Plasmas with Edge Pedestals Limited by Turbulence in DIII-D
D. R. Ernst, A. Bortolon, C. S. Chang +16
Multi-machine empirical scaling predicts an extremely narrow heat exhaust layer in future high magnetic field tokamaks, producing high power densities that require mitigation. In t…
ELM-free Enhanced Dα H-mode with Near Zero NBI Torque Injection in DIII-D Tokamak
T. Macwan, K. Barada, J. F. Parisi +11
Enhanced H-mode (EDA H-mode), an ELM-free H-mode regime, is explored in neutral beam heated, lower single null plasmas with near zero torque injection. This regime exhibits a…
Characterization of mesoscopic turbulent transport events with long-radial-range correlation in DIII-D H-mode plasmas
R. Hong, T. L. Rhodes, Y. Ren +6
A dimensionless collisionality scan has been performed in H-mode plasmas on DIII-D tokamak, with detailed measurements of intermediate-to-high wavenumber turbulence using Doppler b…
Gyrokinetic GENE simulations of DIII-D near-edge L-mode plasmas
T. F. Neiser, F. Jenko, T. A. Carter +7
We present gyrokinetic simulations with the GENE code addressing the near-edge region of an L-mode plasma in the DIII-D tokamak. At radial position , simulations with the i…
Resolving ECRH deposition broadening due to edge turbulence in DIII-D by heat deposition measurement
Michael W Brookman, Matthew B Thomas, Jarrod Leddy +7
Interaction between microwave power, used for local heating and mode control, and density fluctuations can produce a broadening of the injected beam, as confirmed in experiment and…
Resolving ECRH deposition broadening due to edge turbulence in DIII-D by 3D full-wave simulations
Matthew B Thomas, Michael W Brookman, Max E Austin +5
Edge plasma density fluctuations are shown to have a significant effect on the electron cyclotron resonance heating (ECRH) beam in the DIII-D tokamak. Experimental measurements of…
