Originální abstrakt

Environmental scanning electron microscopes offer wide possibilities for the exploration of various types of specimens, especially non-conductive and wet specimens containing different material phases. The evaluation of pressure on the secondary electrons trajectory is one of the important parameter by design of scintillation detector of secondary electrons. The final process is influenced by the size and the shape of the apertures used to separate areas with different pressure gradient. The comparison of the aperture with circular hole and aperture with Laval nozzle is the aim of this article.

Klíčová slova
