WebA wide range of secondary signals are produced when the incident electrons interact with a thin specimen.27These signals are categorized according to their corresponding analytical information: (1) imaging modes in real space, (2) diffraction modes in reciprocal space, (3) spectroscopy mode in energy space, and (4) in temporal domains. WebGas ionization detectors, such as the Geiger—Müller counter or the proportional counter, operate on the principle of collecting and increasing the number of ions produced in a gas when ionizing radiation strikes it. Semiconductor detectors collect the ionization produced when radiation interacts with Si or Ge semiconductors. floorscape creations
