Bremsstrahlung produced by a high-energy electron deflected in the electric field of an atomic nucleus. In particle physics, bremsstrahlung / ˈ b r ɛ m ʃ t r ɑː l ə ŋ / [1] (German pronunciation: [ˈbʁɛms.ʃtʁaːlʊŋ] ⓘ; from German bremsen 'to brake' and Strahlung 'radiation') is electromagnetic radiation produced by the deceleration of a charged particle when deflected by ...
Characteristic X-rays are produced when an element is bombarded with high-energy particles, which can be photons, electrons or ions (such as protons). When the incident particle strikes a bound electron (the target electron) in an atom, the target electron is ejected from the inner shell of the atom.
Commercially available medical linacs produce X-rays and electrons with an energy range from 4 MeV up to around 25 MeV. The X-rays themselves are produced by the rapid deceleration of electrons in a target material, typically a tungsten alloy, which produces an X-ray spectrum via bremsstrahlung radiation. The shape and intensity of the beam ...
X-rays are emitted as the electrons slow down (decelerate) in the metal. The output spectrum consists of a continuous spectrum of X-rays, with additional sharp peaks at certain energies (see graph on right). The continuous spectrum is due to bremsstrahlung, while the sharp peaks are characteristic X-rays associated with the atoms in the target.
The radiation produced in this way has a characteristic polarization, and the frequencies generated can range over a large portion of the electromagnetic spectrum.

X-rays are produced when electrons are accelerated or decelerated. (This is why young children are warned to keep their distance from old televisions). Tungsten is a good source for producing this kind of radiation due to its high atomic number and high melting point. The high-energy electrons formed in the cathode side of an X-ray tube can ...

Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.
