Modeling of hydrocarbon species in ECR methane plasmas

ECR methane laboratory plasmas are modeled using both a simple zero-dimensional particle balance model and a fully kinetic model. The kinetic model consists of a two-dimensional in space, three-dimensional in velocity space particle-in-cell model with Monte-Carlo collisions in which electrons, ions and neutrals are treated as particles, moving in self-consistent electric and external magnetic fields. The model results are discussed and compared with experimental data.
