Usage of Segmental Ionization Detector in Environmental Conditions.

Popis výsledku v původním jazyce

Environmental scanning electron microscope operates with the gaseous environment in the specimen chamber. This environment causes specific conditions for the detection of signal electrons. Classical Everhart-Thornley detector cannot be exploited for thedetection of secondary electrons because of the impossibility to use high enough electric field in a gaseous environment to add sufficient energy to secondary electrons for efficient scintillation. Ionization detector is therefore used for the detectionof signal electrons in environmental SEM most frequently. At this detector a plate electrode with positive potential is positioned above the specimen, which lays on a grounded specimen holder. At operation signal electrons from the specimen are accelerated in electrical field to the positive electrode and are amplified in the process of impact ionisation in a gaseous environment. The positive electrode of the ionisation detects products of ionisation collisions caused by secondary, backs
