Electron Guns
Electron guns are devices that emit a beam of electrons. In the context of space and astronautical engineering, electron guns are commonly used in spacecraft propulsion systems, such as ion thrusters and Hall effect thrusters. In these systems, an electron gun is used to ionize a propellant, such as xenon, creating a plasma that is accelerated by an electric field to generate thrust. Electron guns are also used in scientific instruments, such as electron microscopes and particle accelerators, to produce a focused beam of electrons for imaging or analysis purposes.
