| Abstract | ||
| In this research a computational simulation has been carried out on the design and properties of the electrostatic mirror and a mathematical expression has been suggested to represent the axial potential of an electrostatic mirror. The electron beam path using the Bimurzaev techniquehad been investigated as mirror trajectory with the aid of Runge – Kutta method. The spherical and chromatic aberration coefficients of mirror has computed and normalized in terms of the focal length. The choice of the mirror depends on the operational requirements. The Electrode shape of mirror two electrodes has been determined by using package SIMION computerprogram. Computations have shown that the suggested potentials give good result for low value spherical and chromatic aberration Cs/Fr= - 8.05, Cc/Fr=- 9.1, L=8mm, A=500volt, which give a good indicator for designing the mirrors | ||
