Dissipative continuum model for self-organized pattern formation during ion-beam erosion
A continuum model, based on the damped Kuramoto-Sivashinsky equation, is shown to reproduce the morphology evolution during ion sputtering quite successfully. In a very narrow range of the damping parameter a , the alignment of the structures into hexagonal domains is obtained under normal incidence of ions with striking resemblance to the experimentally observed dot patterns. The origin of thi...

For pure metals, some correlation between erosion reasons for fly ash–borne damage of power generation comrate and hardness has been shown.[4] However, se...
متن کاملErosion/redeposition analysis: status of modeling and code validation for semi-detached tokamak edge plasmas
We are analyzing erosion and tritium codeposition for ITER, DIII-D, and other devices with a focus on carbon divertor and metallic wall sputtering, for detached and semi-detached edge plasmas. Carbon chemical-sputtering/hydrocarbon-transport is computed in detail using upgraded models for sputtering yields, species, and atomic and molecular processes. For the DIII-D analysis this includes proto...

متن کاملElectron Beam Ion Sources, Ion Optical Elements and Beam Diagnostics for Particle Accelerators
Electron Beam Ion Sources (EBISs) provide highly charged ions (HCIs) for a variety of investigations and applications, e.g. amongst others as injection source for particle accelerators. EBISs feature a lot of advantages which qualify them for accelerator injection, and which partly compensate for their comparatively low number of particles. DREEBIT GmbH provides a family of compact EBISs based ...
