An electron beam is a stream of electrons accelerated to high velocities within a vacuum. The process begins with an electron source, typically a filament (cathode), which is heated to produce electrons via thermionic emission. By applying a high voltage between this cathode and an anode, an electric field is established. This field accelerates the electrons, forming them into a focused beam that can be directed for various applications.
