Mitigation of Initial Transients in Total-f Gyrokinetic Turbulence Simulations Using Neoclassically Relaxed Distribution Function
S. Ku, R. Hager, C. S. Chang +2
Total-f five-dimensional gyrokinetic simulations are essential for self-consistent studies of multi-scale, multiphysics transport in the edge region of diverted tokamak plasmas. Ho…

A toroidally spectral field solver in the X-point Gyrokinetic Code for accurate simulation of reduced magneto-hydrodynamic modes
Robert Hager, C. S. Chang, Thomas Gade +5
A new field solver has been implemented in the global electromagnetic total- gyrokinetic particle-in-cell code XGC to extend the code's capability to large-scale reduced MHD-typ…

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…
