Abstract :
Summary form only given. Present work contents results about ribbon beam gun construction and its application for plasma sheet production and thin films deposition if hydrocarbon gas is used as working gas. 3 mm diameter collector movable in two coordinates perpendicularly beam direction show beam density distribution. Plasma density near beam axis was about 10/sup 10/-10/sup 11/ cm/sup -3/. Such plasma parameters allow to use it for thin film deposition. Glass substrates were disposed at different distances X from beam and plasma axis. Experiments with inert gas (argon) show that the most probable etching process is ion sputtering. Film growth takes place due to hydrocarbon radicals diffusion toward substrate. As ions and radicals production takes place because of electron beam interaction with gas molecules we are able to calculate ions and radicals distributions.
