Gyrokinetic prediction of core tungsten peaking in a WEST plasma with nitrogen impurities
J. Dominski, P. Maget, O. Manas +7
Tungsten peaking is predicted in the core of a WEST plasma with total-f gyrokinetic simulations, including both collisional and turbulent transport. This prediction is validated wi…
Doubling Fusion Power with Volumetric Optimization in Magnetic Confinement Fusion Devices
J. F. Parisi, J. W. Berkery, A. Sladkomedova +17
A technique, volumetric power optimization, is presented for enhancing the power output of magnetic confinement fusion devices. Applied to a tokamak, this approach involves shiftin…
Neoclassical transport of tungsten ion bundles in total-f neoclassical gyrokinetic simulations of a whole-volume JET-like plasma
J. Dominski, C. S. Chang, R. Hager +3
The application of a bundling technique to model the diverse charge states of tungsten impurity species in total-f gyrokinetic simulations is demonstrated. The gyrokinetic bundling…
How eigenmode self-interaction affects zonal flows and convergence of tokamak core turbulence with toroidal system size
Ajay C. J., Stephan Brunner, Ben McMillan +3
Self-interaction is the process by which a microturbulence eigenmode that is extended along the direction parallel to the magnetic field interacts with itself non-linearly. This ef…
Verification of the global gyrokinetic stellarator code XGC-S for linear ion temperature gradient driven modes
Michael D. J. Cole, Robert Hager, Toseo Moritaka +5
XGC (X-point Gyrokinetic Code) is a whole-volume, total-f gyrokinetic particle-in-cell code developed for modelling tokamaks. In recent work, XGC has been extended to model more ge…
ORB5: a global electromagnetic gyrokinetic code using the PIC approach in toroidal geometry
E. Lanti, N. Ohana, N. Tronko +20
This paper presents the current state of the global gyrokinetic code ORB5 as an update of the previous reference [Jolliet et al., Comp. Phys. Commun. 177 409 (2007)]. The ORB5 code…
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…
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…
