Applications
The most common use of electron guns is in cathode ray tubes, which were widely used in computer and television monitors. An electron gun can also be used to ionize particles by adding or removing electrons from an atom. This technology is sometimes used in mass spectrometry in a process called electron ionization to ionize vaporized or gaseous particles.More powerful electron guns are used for welding, metal coating, 3D metal printers, metal powder production and vacuum furnaces.
