title: Redesign of the scanning electron microscope for parallel energy spectral acquisition.
abstract: This paper presents a scanning electron microscope (SEM) design that is compatible with parallel electron energy spectrum acquisition. The SEM should in principle be capable of capturing the energy spectrum of all scattered electrons simultaneously, from low energy secondary electrons to elastic backscattered electrons. Preliminary simulation results predict that the beam separator spectrometer will have a relatively high transmission-energy resolution performance, comparable or better than the cylindrical mirror analyzer (CMA), while at the same time being able to capture the entire energy range of scattered electrons.
