X-rays are produced when electrons strike a metal target. The electrons are liberated from the heated filament and accelerated by a high voltage towards the metal target.The X-rays are produced when the electrons collide with the atoms and nuclei of the metal target.-rays are produced when electrons strike a metal target. The electrons are liberated from the heated filament and accelerated by a high voltage towards the metal target.
Heat is considered the undesirable product of this conversion process; therefore X-radiation is created by taking the energy from the electrons and converting it into photons. This very specific energy conversion takes place in the X-ray tube. Construction of the X-ray tube.
