Abstract

The authors see an analogy between a molecular beam and light beam13. In the case of optical modelling of an effusion molecular beam, in a simulation system the light from the source was introduced via a diffusion ground glass plate into the "effusion" channel. The inside of the chanel was lined with the corrugated aluminium foil of a high reflection coefficient and the light was reflected from the wall in chaotic directions, just like molecules from the wall of the actual channel (Fig. 7). The intensity of the light beam distribution was measured with a photodetector. This means that information about high vacuum processes can be received from investigations performed under normal pressure.
