Analysis of Whirling of Gas Flow within the Specimen Chamber of ESEM
Bayer, Robert
The usage of an Environmental scanning electron microscope (ESEM) brings the possibility of studying many kinds of materials and chemical reactions never studied before. In this article there are compared and analyzed several simulation results of gas flow in the specimen chamber of ESEM with high gas pressure throughout the whole volume except on its optical axis, where low gas pressure is needed.

Influence of the cross-section of gas molecules upon detection on the environmental SEM
Neděla, Vilém ; Romanovský, Vladimír
Environmental scanning electron microscopy exploits presence of gas or water vapour in the specimen chamber. Molecules of the gaseous environment can be ionised by electrons, which can compensate the surface charge on thespecimen (at the pressure approx. 200 Pa). At higher pressure of gases and water vapour in the specimen chamber (more than 609 Pa) specimens with content of water can be observed.
