Gyrokinetic continuum simulation of turbulence in a straight openfieldline plasma
Here, fivedimensional gyrokinetic continuum simulations of electrostatic plasma turbulence in a straight, openfieldline geometry have been performed using a full discontinuousGalerkin approach implemented in the Gkeyll code. While various simplifications have been used for now, such as longwavelength approximations in the gyrokinetic Poisson equation and the Hamiltonian, these simulations include the basic elements of a fusiondevice scrapeoff layer: localised sources to model plasma outflow from the core, crossfield turbulent transport, parallel flow along magnetic field lines, and parallel losses at the limiter or divertor with sheathmodel boundary conditions. The set of sheathmodel boundary conditions used in the model allows currents to flow through the walls. In addition to details of the numerical approach, results from numerical simulations of turbulence in the Large Plasma Device, a linear device featuring straight magnetic field lines, are presented.
