The first 4D (axisymmetric) high-order continuum gyrokinetic transport simulations that span
the magnetic separatrix of a tokamak are presented. The modeling is performed with the …

The properties of the boundary plasma in a tokamak are now recognized to play a key role
in determining the achievable fusion power and the lifetimes of plasma-facing components …

In this paper, we propose a new conservative hybrid finite element-finite difference method
for the Vlasov equation. The proposed methodology uses Strang splitting to decouple the …

COGENT is a continuum gyrokinetic code for edge plasmas being developed by the Edge
Simulation Laboratory collaboration. The code is distinguished by application of the fourth …

Plasmas with varying collisionalities occur in many applications, such as tokamak edge
regions, where the flows are characterized by significant variations in density and …

This review summarizes the presentations and discussions by experts in the fields of edge
plasma physics and plasma–material interactions at a workshop organized for the purpose …

New kinetic Landau-fluid closures, based on the cutoff Maxwellian distribution, are derived.
A special static case is considered (the frequency ω= 0⁠). In the strongly collisional regime …

An ion temperature anisotropy model including cross‐field drifts has been implemented in
the 2D transport code UEDGE. Two ion temperature equations are solved in the model to …

Understanding tokamak exhaust-power heat loads on divertor plates depends critically on
having a realistic model of the scrape-off layer (SOL) plasma. The Braginskii fluid model is …

Recent results are presented of plasmas transport phenomena in the edge region of
tokamak devices. Fluid transport modeling results using UEDGE are given for plasma-wall …
