چکیده انگلیسی
The design and construction of an electron energy analyzer for the study of electron impact processes in atoms, molecules and solids is described. The analyzer incorporates a 180° hemispherical deflector and five-element entrance optics. Focusing characteristics and angular behavior of the analyzer have been investigated by using the electron-ray tracing simulation program, SIMION. The entrance lens system to the hemispherical deflector has been designed to have high collection efficiency for low-energy electrons. The fringing field correction has been done by tilting the input beam angle outward for real aperture configuration.
