Verification of a Fully Implicit Particle-in-Cell Method for the Formalism of Electromagnetic Gyrokinetics in the XGC Code
Benjamin J. Sturdevant, S. Ku, L. Chacón +8
A fully implicit particle-in-cell method for handling the -formalism of electromagnetic gyrokinetics has been implemented in XGC. By choosing the -formali…
Constructing a new predictive scaling formula for ITER's divertor heat-load width informed by a simulation-anchored machine learning
C. S. Chang, S. Ku, R. Hager +6
Understanding and predicting divertor heat-load width is a critically important problem for an easier and more robust operation of ITER with high fusion gain. Previous predic…
Comparison of edge turbulence characteristics between DIII-D and C-Mod simulations with XGC1
I. Keramidas Charidakos, J. R. Myra, S. Ku +4
The physical processes taking place at the edge region are crucial for the operation of tokamaks as they govern the interaction of hot plasma with the vessel walls. Numerical model…
A tight-coupling scheme sharing minimum information across a spatial interface between gyrokinetic turbulence codes
Julien Dominski, Seung-Hoe Ku, Choong-Seock Chang +5
A new scheme that tightly couples kinetic turbulence codes across a spatial interface is introduced. This scheme evolves from considerations of competing strategies and down-select…
Analysis of equilibrium and turbulent fluxes across the separatrix in a gyrokinetic simulation
I. Keramidas Charidakos, J. R. Myra, S. Parker +4
The SOL width is a parameter of paramount importance in modern tokamaks as it controls the power density deposited at the divertor plates, critical for plasma-facing material survi…
Gyroaveraging operations using adaptive matrix operators
Julien Dominski, Seung-Hoe Ku, Choong-Seock Chang
A new adaptive scheme to be used in Particle-In-Cell codes for carrying out gyroaveraging operations with matrices is presented. This new scheme uses an intermediate velocity grid…
