Signal Detection by Scintillation Detector from Organic and Inorganic Specimens in Environmental SEM
 Neděla, Vilém
This article deals with the principle of the function and the example of practical application of a scintillation detector in Environmental scanning electron microscopy. Exploitation of this detector is demonstrated on the case of observation of organic and inorganic specimens, while it deals simultaneously with related problems.

Angular distribution of backscattered electrons signal in Environmental Scanning Electron Microscopy
 Wandrol, Petr
The aim of this work was to verify an influence of the collection solid angle on a magnitude of detected signal. The presented results of measurement were gained by an observation of the specimen of carbon covered with a thin layer of gold. The primary beam accelerating voltage was 20kV. The collection solid angle was changed by application of aluminium masks with aperture diameters 2,3,4,8,16 mm mounted on scintillator. As a working environment in the specimen chamber air and saturated water vapour were used.
