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…
Gyrokinetic analysis and simulation of pedestals, to identify the culprits for energy losses using fingerprints
M. Kotschenreuther, X. Liu, D. R. Hatch +14
Fusion performance in tokamaks hinges critically on the efficacy of the Edge Transport Barrier (ETB) at suppressing energy losses. The new concept of fingerprints is introduced to…
Effect of Scrape-Off-Layer Current on Reconstructed Tokamak Equilibrium
J. R. King, S. E. Kruger, R. J. Groebner +4
Methods are described that extend fields from reconstructed equilibria to include scrape-off-layer current through extrapolated parametrized and experimental fits. The extrapolatio…
Global Gyrokinetic Simulation of Tokamak Edge Pedestal Instabilities
Weigang Wan, Scott E. Parker, Yang Chen +3
Global electromagnetic gyrokinetic simulations show the existence of near threshold conditions for both a high- kinetic ballooning mode (KBM) and an intermediate- kinetic ver…
FACETS - a Framework for Parallel Coupling of Fusion Components
John R. Cary, Ammar Hakim, Mahmood Miah +12
Coupling separately developed codes offers an attractive method for increasing the accuracy and fidelity of the computational models. Examples include the earth sciences and fusion…
