Electron Beams
Electron beams are streams of high-energy electrons that are used in various applications in space and astronautical engineering. They are produced by accelerating electrons to high speeds using electric fields and then focusing them into a beam using magnetic fields. Electron beams have a wide range of applications, including in spacecraft propulsion, communication systems, and scientific instruments. In spacecraft propulsion, electron beams can be used to generate thrust by ionizing a propellant and accelerating the resulting ions using an electric field. In communication systems, electron beams can be used to generate microwaves for transmitting signals over long distances. In scientific instruments, electron beams can be used to analyze the composition of materials and to create high-resolution images of objects.
