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…
