An electron beam is a stream of electrons accelerated to high velocities within a vacuum. The process typically begins with an electron source, such as a heated filament (cathode), which generates electrons via thermionic emission. A high-voltage power supply creates a strong electric field between the cathode and anode, accelerating these electrons toward a target. Precision control of this acceleration voltage is critical for generating a stable beam used in microscopy, lithography, and welding applications.
