SUMMARY:Collisional Full-F Electromagnetic Gyrokinetic Turbulence Simulati
 ons of the Edge and Scrape-Off Layer with GENE-X
DESCRIPTION:Minisymposium\n\nCollisional Full-F Electromagnetic Gyrokineti
 c Turbulence Simulations of the Edge and Scrape-Off Layer with GENE-X\n\nU
 lbl, Michels, Stegmeir, Jenko\n\nThe future development of magnetic confin
 ement fusion devices depends on the understanding of turbulent transport i
 n the edge and scrape-off layer (SOL). Gyrokinetic simulations count among
  the main tools used in simulations of the plasma core, but additional cha
 llenges are imposed in the edge and SOL. First, steep gradients require th
 e use of a full-f approach for the distribution function. Second, crossing
  the SOL leaves traditional field-aligned coordinate systems ill-defined. 
 Third, in the cold plasma edge, the collisionality increases, requiring a 
 realistic modelling of collisional effects. In this talk we present an ove
 rview of the gyrokinetic turbulence code GENE-X, with a focus on newly dev
 eloped collision models. GENE-X is an Eulerian-type "continuum" code that 
 solves the gyrokinetic Vlasov equation on a grid. It is especially targete
 d towards edge and SOL simulations and implements a collisional, full-f, e
 lectromagnetic, gyrokinetic turbulence model. The problems of field-aligne
 d coordinate systems are avoided by using the flux-coordinate independent 
 (FCI) approach. Collisions are modelled with a Fokker-Planck type Lenard-B
 ernstein/Dougherty collision operator, which accounts for numerically exac
 t conservation of particle density, momentum and energy. With these capabi
 lities, GENE-X is able to perform simulations in realistic, diverted tokam
 ak geometries and model turbulent transport in magnetic confinement fusion
  devices.\n\nDomain: Computer Science and Applied Mathematics, Physics
