As a matter of fact, electron gun has already been widely adopted in various fields. In general, the electron gun is a device used to form an electron beam. In recent years, electron guns have been adopted in welding, lithography and treatment of pollutants. With this in mind, this study will introduce the principle of the electron gun and its application in the three fields respectively. In the electron gun, the cathode is electrically heated in a vacuum to emit hot electrons. Applying a strong potential to the anode, the emitted electrons are accelerated at a given energy, thus forming an electron beam. This has led to the widespread use of electron beams. By studying the rapid development of electron beam applications generated by electron guns, it is shown that electron guns have excellent prospects for development. Overall, these results shed light on guiding further exploration of electron gun development.
