WebBackscattered electron imaging explained. Backscattered electrons (BSEs) are generated by elastic scattering events. When the electrons in the primary beam travel close to the atom’s nuclei in the specimen, their … WebIn order to form an image with BSE (backscattered electrons), a detector is placed in their path. When they hit the detector a signal is produced which is used to form the TV image. All the elements have different sized nuclei. As the size of the atom nucleus increases, the number of BSE increases. Thus, BSE can be used to get an image that ... WebThe SE detector is placed at the side of the electron chamber, at an angle, in order to increase the efficiency of detecting secondary electrons. These two types of electrons are the most used signals by SEM users for imaging. Not all SEM users require the same type of information, so the capability of having multiple detectors makes SEM a very ... boilers iusa
