The vast majority of the Bremsstrahlung

: German term for "Braking radiation." Electromagneticradiation from a charged particle as it slows down (decelerates) or as it changes direction due to near collisions with other particles.
Shooting a beam of high-energy electrons at a tungsten target produces bremsstrahlung
. The bremsstrahlung
photons then rip apart deuterium, releasing neutrons.
This is not enough energy to eject a shell electron for characteristic x-rays or for [E.sub.max] for bremsstrahlung

The ionization due to photons emitted by radiative processes (i.e., bremsstrahlung
and fluorescence photons) is not to be included in dg.
Anomalous microwave emission is often discussed in the context of the three major radio emission mechanisms: synchrotron, bremsstrahlung
, and thermal (i.e., vibrational) dust emission.
Free-free processes are inverse Bremsstrahlung
mechanisms, whereby a free electron and an ion interact during which time the combined species is able to absorb a photon [41, p.138].
Accelerators with high photon flux require a high-Z material, typically tungsten, for the bremsstrahlung
target because it can withstand the high heat from the electron beam.
Such high-energy photons are typically the result of bremsstrahlung
, a process that takes its name from the German words for "braking radiation." When a high-speed electron slams into a much heavier atom, the kinetic energy shed during the electron's sudden deceleration is east off in a photon, says Smith.
This results in the emission of high-energy, X-ray photons by a process called bremsstrahlung
(a German word meaning "braking radiation").
