Bremsstrahlung physics Britannica

The first mechanism involves the rapid deceleration of a high speed electron as it enters the electric field of a nucleus. During this process the electron is deflected and emits a photon of x-radiation. This type of x-ray is often referred to as bremsstrahlung or "braking radiation".

According to the laws of classical electrodynamics, this deceleration gives rise to electromagnetic radiation which is mainly radiated perpendicular to the direction of acceleration for energies below 50 keV. The X-ray tube in this apparatus produces such x-rays by accelerating electrons from a heated cathode into an anode at high voltage.

The electrons are produced by a heated tungsten filament, the cathode. X-ray tube enclosures are generally constructed from glass but may be metal and/or ceramic.

WebThe X-ray tubes produce X-rays when an energetic beam of electrons hits a metallic target (anode). The resulting rapid deceleration of the electrons causes the emission of white radiation ( Bremsstrahlung) as well as discrete, much more intense radiation at the characteristic wavelength of emission of the target metal.
