Abstract:Modelling of ECR-heated methane plasmas was done using a particle-in-cell code with collisions (PIC MCC) to get a better understanding in the problem of carbon layer production and chemical sputtering in such plasmas, which serve as a model system of divertor plasmas being dominated by carbon sputtering, especially at detached conditions. A fully kinetic model (PIC MCC, resolving also the sheath in front of the wall) including all relevant species and their reactions (neutrals, ions, electrons) was developed a… Show more
“…As discussed before we have studied the formation of dust structures in low temperature laboratory plasmas with a self-consistent particle simulation [94,95]. Although PIC simulations proved to be a powerful tool for studying dusty plasmas, the PIC method has a considerable drawback.…”

Several applications of PIC simulations for understanding basic physics phenomena in low-temperature plasmas are presented: capacitive radiofrequency discharges in Oxygen, dusty plasmas and negative ion sources for heating of fusion plasmas. The analysis of these systems based on their microscopic properties as accessible with PIC gives improved insight into their complex behavior. These studies are results of joint efforts over about one decade

“…In previous work [2,3] we have studied the formation of dust structures in low temperature laboratory plasmas with a self-consistent particle simulation. For this purpose a 3D particle-in-cell code with Monte Carlo collisions (PIC-MCC), resolving also the sheath in front of the wall including all relevant species (neutrals, ions, and electrons) and their reactions, was developed and applied [2].…”

“…A general multi-species electrostatic PIC code was developed including all collisions between electrons, ions and neutrals. This code was successfully applied to the study of low temperature methane plasmas [18] (which are model systems for chemical sputtering studies), capacitive rf discharges [19] and complex plasmas [20]. Plasmas which, in addition to electrons, ions and neutrals, also contain microscopic particles of nanometer -micrometer size are called dusty (complex) plasmas [17] (Chap.…”
The problem of plasma-wall interaction requires multi-scale methods (molecular dynamics, kinetic Monte Carlo) for both the material and the plasma. One possible concept for such multi-scale modelling is presented, including validation strategies.
