Electron dynamics and plasma-infusion are crucial for understanding plasma and material
recycling, cooling, and the plasma-material interactions (PMI) for plasma facing surfaces for …

Surface free energy has been hypothesized as the cause behind the experimental evidence
(Parish et al., 2014) of a strong correlation between crystallographic orientation and surface …

The interaction of hydrogen (H) with dislocations in tungsten (W) must be understood in
order to model the mechanical response of future plasma-facing materials for fusion …

Plasma-facing components of future fusion reactors will have tungsten-based materials as
armor. Annealed pure tungsten is brittle at room temperature restricting its use as plasma …

We have performed a combined study using transmission electron microscopy (TEM),
nuclear reaction analysis (NRA) and nano-indentation (NI) techniques to reveal the impact …

The unique ability of grain boundaries to act as effective sinks for radiation damage plays a
significant role in nanocrystalline materials due to their large interfacial area per unit volume …

The formation of helium cavities in coarse-grained materials produces hardening
proportional to the number density and size of the cavities and due to the interaction of …

A new experimental facility constructed at UCLA for the simulation of high heat flux effects on
plasma-facing materials is described. The High Energy Flux Test Facility (HEFTY) is …

The performance of plasma facing components (PFCs) is critical for ITER and future
magnetic fusion reactors. The ITER divertor will be tungsten, which is the primary candidate …

Tritium retention and microstructural modifications due to helium accumulation are two of the
main concerns regarding plasma-facing materials in fusion applications. Crystal defects in …
