How does x-ray work?
An x-ray system uses x-ray photons to affect material properties. These photons are generated by first electrically heating a filament. The heated filament gives off electrons through a process called thermionic emission. The electrons are then accelerated by applying a voltage potential. The accelerated electrons are directed to a target made of a high atomic number (high Z) material. When the accelerated electrons interact with the target, a portion of their energy gets converted into x-ray photons.
This process takes place in vacuum; however, once the photons are created, they escape the vacuum by penetrating through the target into atmospheric pressure. Finally, these photons are ready to be used in production. As material passes in front of the target, x-ray photons penetrate into the material and work their science!
