A Propagator-based Multi-level Monte Carlo Method for Kinetic Neutral Species in Edge Plasmas
Gregory J. Parker, Maxim V. Umansky, Benjamin D. Dudson
We propose and investigate a new multi-level Monte Carlo scheme for numerical solutions of the kinetic Boltzmann equation for neutral species in edge plasmas. In particular, this m…

Coupling Fluid Plasma and Kinetic Neutral Models using Correlated Monte Carlo Methods
Gregory J. Parker, Maxim V. Umansky, Benjamin D. Dudson
While boundary plasmas in present-day tokamaks generally fall in a fluid regime, neutral species near the boundary often require kinetic models due to long mean-free-paths compared…
