When the beam of electrons hits the sample, it causes secondary electrons to be released from the sample which are detected to provide an image based off the topography of the surface. The above spectrum is generated by integrating all the pixels from an individual EDS map. Interaction of an electron beam with a sample target produces a variety of emissions, including x-rays.
