Spacecraft heat shield study in the DIII-D tokamak
Dmitri M. Orlov, Evdokiya G. Kostadinova, Igor Bykov +33
We report a new experimental platform developed at the DIII-D National Fusion Facility to investigate carbon ablation and spallation under extreme heat fluxes relevant to fusion pl…
Improved Particle Confinement with Resonant Magnetic Perturbations in DIII-D Tokamak H-Mode Plasmas
N. C. Logan, Q. Hu, C. Paz-Soldan +9
Experiments on the DIII-D tokamak have identified a novel regime in which applied resonant magnetic perturbations (RMPs) increase the particle confinement and overall performance.…
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…
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…
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…
Evaluation of silicon carbide as a divertor armor material in DIII-D H-mode discharges
T. Abrams, S. Bringuier, D. M. Thomas +7
Silicon carbide (SiC) represents a promising but largely untested plasma-facing material (PFM) for next-step fusion devices. In this work, an analytic mixed-material erosion model…
