Gyrokinetic equilibria of high temperature superconducting magnetic mirrors
Maxwell H. Rosen, Manaure Francisquez, James Juno +2
High-temperature superconducting (HTS) magnets and other advances have led to renewed interest in magnetic mirrors for fusion energy. The non-Maxwellian nature of mirror plasmas ne…
A Conservative Discontinuous Galerkin Algorithm for Particle Kinetics on Smooth Manifolds
Grant Johnson, Ammar Hakim, James Juno
A novel, conservative discontinuous Galerkin algorithm is presented for particle kinetics on manifolds. The motion of particles on the manifold is represented using using both cano…
Gyrokinetic Simulations of a Low Recycling Scrape-off Layer without a Lithium Target
Akash Shukla, Jonathan Roeltgen, Michael Kotschenreuther +7
Low-recycling regimes are appealing because they entail a high edge temperature and low edge density which are good for core confinement. However, due to considerably enhanced heat…
Constructing Field Aligned Coordinate Systems for Gyrokinetic Simulations of Tokamaks in X-point Geometries
Akash Shukla, Ammar Hakim, James Juno +2
Structures in tokamak plasmas are elongated along the direction of the magnetic field and short in the directions perpendicular to the magnetic field. Many tokamak simulation codes…
Discontinuous Galerkin Representation of the Maxwell-Jüttner Distribution
Grant Johnson, Ammar Hakim, James Juno
Kinetic simulations of relativistic gases and plasmas are critical for understanding diverse astrophysical and terrestrial systems, but the accurate construction of the relativisti…
