Molecular dynamics studies of the chemical sputtering of carbon-based materials by hydrogen bombardment
A central issue in the performance of tokamak fusion devices is the choice of the plasma-facing materials. During the device operation the plasma-facing surfaces are subject to extreme heat and particle loads, as they are impinged on by escaped fusion plasma particles. Although carbon-based materials have excellent thermomechanical properties in view of the high heat flux, their use in the next...
متن کاملDifferential Sputtering Behavior of Pyrolytic Graphite and Carbon-Carbon Composite Under Xenon Bombardment
A differential sputter yield measurement technique is described, which consists of a quartz crystal monitor that is swept at constant radial distance from a small target region where a high current density xenon ion beam is aimed. This apparatus has been used to characterize the sputtering behavior of various forms of carbon including polycrystalline graphite, pyrolytic graphite, and PVD-infilt...
متن کاملGeneration of Dust Seeds by Sputtering of Carbon-based Plasma Facing Materials under Low-energy H/D/T Ion Bombardment
Sputtering properties of graphite and amorphous carbon substrates by hydrogen (H), deuterium (D), and tritium (T) at low incident energies have been studied with the use of classical molecular dynamics (MD) simulations. The sputtering simulations used here are accumulative in the sense that the surface modification due to impinging species are self-consistently taken into consideration. The sim...
متن کاملFlux dependence of carbon chemical erosion by deuterium ions
The chemical erosion of carbon in interaction with a hydrogen plasma has been studied in detail in ion beam experiments, and erosion yield values are available as a function of ion energy and surface temperature. However, the conditions in the ITER divertor cannot be simulated by ion beam experiments, especially as far as ion flux is concerned. Therefore, a joint attempt was made through the EU...
متن کاملStructural and chemical evolution of single-wall carbon nanotubes under atomic and molecular deuterium interaction
The interaction of atomic (D) and molecular (D2) deuterium, as present in a (D + D2) gas mixture, with single-wall carbon nanotubes (SWNTs) has been studied by means of a combination of scanning electron microscopy, transmission electron microscopy and X-ray photoelectron spectroscopy. The SWNT samples were exposed to the gas mixture, produced by thermal dissociation of D2 on a hot W filament, ...
