Abstract: A scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) apparatus that includes a scanning electron microscope, an x-ray detector, and an auxiliary acceleration voltage source. The scanning electron microscope includes a sample holder, and a layered electron beam column arranged to output an electron beam towards the sample holder at an initial beam energy. The auxiliary acceleration voltage source is to apply an auxiliary acceleration voltage between the sample holder and the layered electron beam column to accelerate the electron beam to a final beam energy. At the final beam energy, the electron beam is capable of generating x-rays at multiple wavelengths from a larger range of atomic species than the electron beam at the initial beam energy.
