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…
An explicit multiscale pseudo orbit-averaging time integration algorithm
Maxwell H. Rosen, Manaure Francisquez, Gregory W. Hammett
We present an explicit multiscale algorithm for solving differential equations for problems with high-frequency modes that can be averaged over by separating and scaling the fast a…
High-throughput full-f gyrokinetics of the tokamak boundary
A. C. D. Hoffmann, M. Francisquez, T. N. Bernard +2
Full-f global gyrokinetic simulations of the plasma boundary have until now required heroic computational efforts and case-by-case expert intervention, precluding systematic parame…
Towards fully predictive gyrokinetic full-f simulations: validation and triangularity studies in TCV
A. C. D. Hoffmann, T. N. Bernard, M. Francisquez +6
Designing economical magnetic confinement fusion power plants motivates computational tools that can estimate plasma behavior from engineering parameters without direct reliance on…
Conservative velocity mappings for discontinuous Galerkin kinetics
Manaure Francisquez, Petr Cagas, Akash Shukla +2
Continuum computational kinetic plasma models evolve the distribution function of a plasma species on a phase-space grid over time. In many problems of interest the distribut…
Axisymmetric Gyrokinetic Simulation of ASDEX-Upgrade Scrape-off Layer Using a Conservative Implicit BGK Collision Operator
D. Liu, J. Juno, G. W. Hammett +3
Collisions play an important role in turbulence and transport of fusion plasmas. For kinetic simulations, as the collisionality increases in the domain of interest, the size of the…
