Abstract:
In work the results of numerical modeling of the long-focus electrostatic energy analyzer based on hexapole-cylindrical field with a concave outer electrode were given. Trajectory analysis of the motion of charged particles in the electron-optical scheme of energy analyzer was carried out. Electron-optical parameters of the energy analyzer were numerically calculated. Luminosity and instrumental function were calculated. The numerical calculation of the electron-optical scheme of energy analyzer was conducted by the "Focus" program for modeling of axially-symmetric systems of corpuscular optics with any electrode geometry.
