This laboratory explores some of the principal phenomena observed at low beam energies. Images prepared at “conventional” beam energies, e.g., 15 keV and above, are compared with low-beam-energy images, e.g., 5 keV and below. The possibility of examining uncoated insulators by taking advantage of enhanced emission of secondary electrons at low energy is also examined.
