Elastic Properties of Plasma- Exposed Tungsten Predicted by Molecular-Dynamics Simulations.
Results of systematic molecular-dynamics computations of the elastic properties of single-crystalline tungsten containing structural defects, voids and over-pressurized He nanobubbles related to plasma exposure of tung sten serving as a plasma-facing component (PFC) in nuclear fusion devices contribute directly to the development of a structure-properties database that is required for the predictive modeling of the dynamical response of PFCs innuclear fusion devices.
Investigation of Hydrogen Glow Discharge Cleaning Side Effects on Tungsten
Hydrogen glow discharge cleaning (H-GDC) is a routine conditioning procedure for the modern tokamaks and the future fusion machines, including ITER. Due to the low energy of hydrogen ions in glow
Investigation of high-temperature-resistant rhenium–boron neutron shields by experimental studies and Monte Carlo simulations
In this study, novel rhenium–boron neutron-shielding high-temperature-resistant materials were designed. The considered samples, Re60–B40, Re58–B42, Re50–B50, and Re40–B60, with different


Effects of sequential tungsten and helium ion implantation on nano-indentation hardness of tungsten
To simulate neutron and helium damage in a fusion reactor first wall sequential self-ion implantation up to 13 dpa followed by helium-ion implantation up to 3000 appm was performed to produce damaged
Observation of a helium ion energy threshold for retention in tungsten exposed to hydrogen/helium mixture plasma
Helium retention is measured in tungsten samples exposed to mixed H/He plasma in the Magnum-PSI linear plasma device. It is observed that there is very little He retention below helium ion impact
The micro-mechanical properties of ion irradiated tungsten
Micro-mechanical testing techniques have proved successful in extracting the properties of bulk materials from small-scale tests. In particular, focussed ion beam (FIB)-machined micro-cantilevers
Mechanical properties of ion-implanted tungsten–5 wt% tantalum
Ion implantation has been used to simulate neutron damage in W–5wt%Ta alloy manufactured by arc melting. Implantations were carried out at damage levels of 0.07, 1.2, 13 and 33 displacements per atom
Impact of helium ion energy modulation on tungsten surface morphology and nano-tendril growth
Time-modulated helium (He) ion energy (e.g. V Bias = −50 + 25sin(2πf RF t), f RF = 13.56 MHz) is demonstrated to strongly affect the development of tungsten (W) surface morphology that results from
