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
