10. Basic plasma theory

Invited

What if you are interested in performing a particle simulation with kinetic electrons and gyrokinetic ions? In principle, the kinetic motion of electrons is described in terms of electric and magnetic fields, while the standard gyrokinetic motion of ions is described in terms of electric and magnetic potentials. The dependence of standard gyrokinetic theory on perturbed potentials, instead of...

51. Electromagnetic full-f continuum gyrokinetic simulation of plasma turbulence in scrape-off layer of ASDEX Upgrade

7. Edge and scrape-off layer/divertor physics

Oral

We report our numerical observation of seeded blob dynamics at the SOL region of tokamak. We have used Gkeyll computational plasma framework to perform our 5D gyrokinetic simulation for helical open magnetic field lines. We simulate for plasma parameters similar to ASDEX upgrade experimental shots. Toroidally elongated coherent density structures (known as plasma blobs) are seeded just outside...
