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…
Dependence of Momentum Transport on the Dominant Turbulence Regime in the DIII-D Tokamak
C. F. B. Zimmermann, C. Chrystal, E. Perez +8
Accurate prediction of toroidal plasma rotation is essential for optimizing confinement and stability in future fusion devices. This work investigates turbulent core momentum trans…
First divertor exposure experiments of a renewable boron pebble aggregate in DIII-D
Erick Martinez-Loran, Angelica Ottaviano, Santhosh T. A. Kumar +21
Boron pebble aggregate was tested for the first time as a high-heat-flux granular plasma-facing material in a tokamak divertor. Exposures of up to $q_{\parallel} = \SI{80}{\MW\per\…
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…
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.…
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…
