An x-ray tube functions as a specific energy converter, receiving electrical energy and converting it into two other forms of energy: x-radiation[1] (1%) and heat (99%). Heat is considered the undesirable product of this conversion process; therefore x-radiation is created by taking the energy from the electrons[2] and converting it into photons[3]. This very specific energy conversion takes place in the x-ray tube.
NB: This article is about the modern vacuum tube. For the first twenty years after Roentgens discovery, all tubes were of the gas type[4].
The x-ray tube contains two principal elements:
filament (also acts as cathode): boils off electrons by thermionic emission[5][6]
target (also acts as anode[7]): electrons strike to produce x-rays
