Effects of Diameter between Electrodes on Properties of Electrostatic Quadrupole Deflector

Abstract

Abstract: This study investigates the impact of varying the electrostatic quadrupole deflector diameter (EQDD) on the image when charged particles undergo deflection. A comparison is made between aberration figures, the kinetic energy of the electron beam, and the flight time concerning different EQDD values. The results showed that the most effective image is created at the image plane when the EQDD is double the radius of the electrostatic quadrupole deflector electrode (r).
