  • Publication number: 20230298845
    Abstract: A decelerating electrode of this energy filter comprises: an electrode pair that has an opening; and a cavity portion that provided in a rotationally symmetrical manner with the center of the opening as the optical axis. Voltages with electric potentials that are substantially the same as that of a charged particle beam are independently applied to the both sides of the decelerating electrode. When an electrical field protrudes into the cavity portion provided in the decelerating electrode, a saddle point having the same electric potential as that of incident charged particles is formed inside the decelerating electrode. The saddle point acts as a high pass filter for incident charged particles at an energy resolution of 1 mV or less. By analyzing charged particles which have been energy-separated, it is possible to measure the energy spectrum and ?E at the high resolution of 1 mV or less.
