Conventional X-ray generators
The four basic components of an X-ray producing machine include:
- a source of electrons
- a vacuum within which the electrons are accelerated
- an energy source which cause the electrons to be accelerated
- a target made of a high atomic number, high melting point metal
- thermionic emission from a heated electrode
- a short (0.1 -0.5 metre) hollow sealed glass tube.
- a potential difference, ie, a voltage applied from a transformer.
- a tungsten target.
