WebJan 9, 2024 · $\begingroup$ @StanMots: By similar arguments applied to the force on a test charge, rather than on a beam of particles. Figure out what the electric force is on a moving charge in the lab frame; transform into the rest frame of the charge and figure out the electric force there; transform that the force calculated in the charge frame back into the lab … WebMay 9, 2024 · Abstract. We first review the significance of resolution and contrast in electron microscopy and the effect of the electron optics on these two quantities. We then outline the physics of the generation of secondary electrons (SEs) and their transport and emission from the surface of a specimen. Contrast and resolution are discussed for ...
