elektronipistoolikäsitteen
The term "elektronipistoolikäsitteen" translates from Finnish to English as "electron gun concept". This refers to the fundamental principle and design behind devices that generate and control a focused beam of electrons. Electron guns are crucial components in a variety of technologies, including cathode ray tubes (CRTs) found in older televisions and monitors, electron microscopes, particle accelerators, and some types of industrial lasers.
At its core, an electron gun operates by thermionic emission. A filament, typically made of tungsten, is
