Transport and deposition of injected hydrocarbons in plasma generator PSI-2

The transport and deposition of hydrocarbons were studied in the stationary plasma of plasma generator PSI-2. CH4 or C2H4 were injected into the plasma at different positions in the target chamber. After an interaction between the plasma and the hydrocarbons, different species are produced, some of them having high sticking probabilities and forming a:CH films on a temperature controlled collector. The film growth is studied in situ for different plasma parameters. The 3D Monte Carlo code ERO including three different sets of atomic data is used to describe the formation of hydrocarbon films.
