"Dynamics of Scrape-off Layer Filaments in Detached Conditions"

David Schworer Nick Walkden Ben Dudson Fulvio Militello Huw Leggate Miles Turner

The here presented work studies the dynamics of filaments using 3D full-f fluid simulations in the presence of detached background profiles. It was found that evolving the neutrals on the time-scale of the filament did not have a significant impact on the dynamics of the filament. In general a decreasing filament velocity with increasing plasma den…

"Influence of the plasma background on 3D scrape-off layer filaments"

D. Schwörer N. R. Walkden H. Leggate B. D. Dudson F. Militello T. Downes M. M. Turner

This paper presents the effect of self-consistent plasma backgrounds including plasma-neutral interactions, on the dynamics of filament propagation. The principle focus is on the influence of the neutrals on the filament through both direct interactions and through their influence on the plasma background. Both direct and indirect interactions infl…
