Abstrakt: The impact of adjusting the distance between the object source and the electrostatic quadrupole deflector on the picture produced when charged particles travel through the deflector is investigated in this study. The time of the fight, kinetic energy of the electron beam, and aberration figures were compared for electrostatic quadrupole deflectors of varying electron beam source distances (d). The results indicated that the best picture may be created at the image plane when the electrostatic quadrupole deflector for distance (d) is one and a half times larger than the radius of the electrode (r).
