Based on the current knowledge, a plasma–liquid interface looks and behaves very
differently from its counterpart at a solid surface. Local processes characteristic to most …

Tungsten–potassium (potassium-doped tungsten or WK), initially known from the electric
filament industry, is a promising plasma-facing material (PFM) in future fusion facilities like …

Superionic and electride behaviors in materials, which induce a variety of exotic physical
properties of ions and electrons, are of great importance both in fundamental research and …

We report observations from the DIII-D tokamak indicating that boron (B) powder injection in
tokamak plasmas improves wall conditions similarly to glow discharge boronization (GDB) …

The application of lithium to plasma facing components (PFCs) has been widely used to
improve plasma performance in magnetic confinement devices. The ability of lithium to …

Controlled particulate injections from the PPPL impurity powder dropper (IPD) into the Large
Helical Device have demonstrated positive effects on the wall conditions on both an intra …

A liquid metal dropper has been developed as a part of the Ion-Gas-Neutral Interactions with
Surfaces 2 (IGNIS-2) facility at The Pennsylvania State University. The dropper has the …

We have used a combination of pico-to-nano temporal/spatial scale computational physics
and chemistry modeling of plasma–material interfaces in the tokamak fusion plasma edges …

Liquid lithium wettability has been investigated on novel zirconium-alloyed porous tungsten
fabricated by the place-holder spark plasma sintering technique. This paper investigates the …

The evolution of point defects is crucial in determining the radiation resistance of materials in
a fusion environment. A comprehensive investigation of diffusion mechanisms for intrinsic …
