X-ray Production

Whenever a charged particle is accelerated or decelerated, it emits energy in the form of photons. This process takes place within an x-ray tube to create x-rays. At one end of the tube is the source of electrons, or the cathode. At the other end of the tube is the tungsten target, or anode.

To produce x-rays, electrons are accelerated from the cathode to the tungsten anode with a high voltage. When the electrons hit the tungsten anode, they are quickly stopped. This rapid change in speed causes the emission of x-ray photons.
