Focused electron beam
WebScanning Electron Microscopy. A scanning electron microscope (SEM) projects and scans a focused stream of electrons over a surface to create an image. The electrons in the beam interact with the sample, thereby producing various signals that can be used to obtain information about the surface’s topography and composition. WebElectron-beam welding of tungsten parts should be thoroughly evaluated on production prototypes before specifying its use. (Author).
