Due to its enviable properties, tungsten is a leading candidate plasma facing material in
nuclear fusion reactors. However, like many other metals, tungsten is known to be affected …

We report a simulation study on the effects of helium (He) bubble size on the morphological
evolution and pattern formation on the surface of tungsten used as a plasma-facing …

Four different types of micro-engineered tungsten surfaces were exposed to low energy
helium plasma, with a planar surface as control. These samples include two surfaces …

Employing a thermodynamic model with previously calculated first-principle energetics as
inputs, we determined the hydrogen (H) concentration at the interstitial and monovacancy as …

Low energy (< 100keV) helium implantation of tungsten has been shown to result in the
formation of unusual surface morphologies over a large temperature range (700–2100° C) …

Tungsten (W) is one of the most important candidates for divertor materials in a magnetically
confined fusion experimental reactor such as the International Thermonuclear Experimental …

We propose a variable-gap energy model for helium bubbles in metals, based on molecular
dynamics (MD) calculations. The emphasis is put on the appropriate description of the …

Bubble growth and gas release during annealing of helium implanted tungsten is described
using a Kinetic Monte Carlo approach. Implantation of tungsten with low energy He ions …

This paper describes the dynamics of helium clustering behaviour within either a nanometer-
sized tendril of fuzz, or a half-space domain, as predicted by a reaction–diffusion model. This …

In this paper, the pressure state of the helium bubble in titanium is simulated by a molecular
dynamics (MD) method. First, the possible helium/vacancy ratio is determined according to …
