Energy and momentum conservation in the Euler-Poincaré formulation of local Vlasov-Maxwell-type systems
Eero Hirvijoki, Joshua W. Burby, David Pfefferlé +1
The action principle by Low [Proc. R. Soc. Lond. A 248, 282--287] for the classic Vlasov-Maxwell system contains a mix of Eulerian and Lagrangian variables. This renders the Noethe…
Charge-conserving, variational particle-in-cell method for the drift-kinetic Vlasov-Maxwell system
Eero Hirvijoki
This paper proposes a charge-conserving, variational, spatio-temporal discretization for the drift-kinetic Vlasov-Maxwell system, utilizing finite-elements for the electromagnetic…
High-performance orbit-following code ASCOT5 for Monte Carlo simulations in fusion plasmas
Jari Varje, Konsta Särkimäki, Joona Kontula +5
We present a novel implementation of a Monte Carlo particle-following code for solving the distribution function of minority species in fusion plasmas, called ASCOT5, and verify it…
Eliminating poor statistics in Monte-Carlo simulations of fast-ion losses to plasma-facing components and detectors
Eero Hirvijoki
With Wendelstein 7-X now up and running, and the construction of ITER proceeding, predicting fast-ion losses to sensitive plasma-facing components and detectors is gaining signific…
Conservative finite-element method for the relativistic Coulomb collision operator
Eero Hirvijoki
This research note documents new developments regarding finite-element discretizations of the relativistic Beliaev-Budker Coulomb collision operator and the nonrelativistic Landau…
