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…
ELMO: An Uncertainty-Aware Simulation-to-Surrogate Workflow for Fast Pedestal Linear-Stability Prediction
Nami Li, X. Q. Xu, T. Osborne +5
Rapid prediction of pedestal linear stability is important for exploring tokamak operating space, uncertainty quantification, and future model-informed control, but mode-resolved m…
Integrating Gyrokinetic Flux Predictions with Ideal MHD Stability Boundaries
J. McClenaghan, K. E. Thome, T. F. Neiser +5
Accurate prediction of pedestal height and width in tokamaks remains a critical issue as it strongly influences the predicted plasma performance of all future reactors. We present…
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…
