Abstract
The electron gun plays an important role in atomic, molecular, and surface physics. Different types of electron guns have been designed for producing different electron beam energies. In this study, we present the modeling and construction of a seven-element electron gun with deflector system for electron impact studies. The electron optics of the electron gun was simulated and optimized using electron-beam ray-tracing simulation program SIMION 3D 7.0. Different operation mode of the gun, afocal, broad, and zoom beam mode, can be accommodated by adjusting various potentials. This modeling proposed here may help to design new types of electron guns and applications using cylinder and aperture lenses in collision experiments.
