Abstract:

An experimental study of the gas molecule conductivity for cylindrical channel with the surface prepared by metal spray technique has been carried out. The dramatically change of a gas conductivity value is observed at the process of residual gas adsorption on a clean metal surface. Vast experimental material on molecular beam scattering and theoretical approach for description of a gas molecules scattering on the solid state surface are used for comparison and interpretation of the received experimental data. A satisfactory agreement between experimental results and numerical simulation of the effect is achieved.
