01 Bremsstrahlung YouTube. The production of bremsstrahlung radiation by mono-energetic electrons in a target which is thick to the electrons has been discussed by many authors (Dyson 1959, Jakshik 1967). The thick-target measurement convolves the electron scattering and stopping with the bremsstrahlung production to produce an x-ray spectrum., Bremsstrahlung, (German: “braking radiation”), electromagnetic radiation produced by a sudden slowing down or deflection of charged particles (especially electrons) passing through matter in the vicinity of the strong electric fields of atomic nuclei. Bremsstrahlung, for example, accounts for continuous X-ray spectra—i.e., that component of X rays the energy of which covers a whole range.

This distinction was reinforced by Charles Barkla (1877–1944) in 1907: superimposed on the spectrally-spread out x-radiation from electron impacts (Bremsstrahlung) was a series of sharp strong peaks characteristic of the anti-cathode metal (fluorescent x-rays) that Barkla showed were polarized. Sommerfeld returned to the issue in 1911 with a The phenomenon of bremsstrahlung (from "braking radiation" in German) applies mostly to particles with an electrical charge whose velocity is close to the speed of light.It occurs when this ultra relativistic particle interacts with a strong electric or magnetic field, which can be natural (the electric field of a nucleus) or produced by man (the field of magnets in an accelerator).
