Electron Gun

An electron gun is a device that generates and emits a focused beam of electrons. It typically consists of a cathode that heats up to release electrons, and an anode that attracts and accelerates them. Electron guns are crucial in various applications, including televisions and computer monitors, where they create images by directing electrons onto a screen coated with phosphorescent materials. They are also used in scientific instruments like electron microscopes, allowing researchers to visualize small objects at high resolutions. Essentially, the electron gun is fundamental to technologies that manipulate and utilize electron streams for various purposes.
