IMAGE PROCESSING TECHNIQUES

b) scintillator-photomultiplier combination which is used for recording secondary electrons. The secondary electrons are detected by a scintillator-photomultiplier combination which is known as the Everhart-Thornley detector. Its construction is shown in Fig. 1.1.2b which is taken form [1.1.2]. The secondary electrons are collected by a grid.
