What does the term bremsstrahlung mean?

braking radiation
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.

Who discovered bremsstrahlung?

This is “braking,” hence the term Arnold Sommerfeld (1868–1951) coined in 1909 of Bremsstrahlung. Wilhelm Conrad Röntgen (1845–1923) had thought in 1895 he had found the elusive longitudinal e-m wave in his discovery of ► x-rays.

What is bremsstrahlung radiation used for?

The bremsstrahlung is still used in radiotherapy, where small linear accelerators produce electron beams that can be either used directly for treatment at a shallow depth, or transformed into gamma rays using alternating magnetic fields.

How is bremsstrahlung measured?

The bremsstrahlung spectra were measured with an HPGe (High Purity Germanium) detector. To measure the axial radiation, the HPGe detector was located behind the straight-through port of the 110º analyzing magnet.

Which rays are called as bremsstrahlung or braking radiation?

Bremsstrahlung is the electromagnetic radiation emitted in the form of photons when a charged particle is decelerated upon striking against another charged particle. This radiation gives a continuous X-ray spectrum. This is also known as “braking radiation”.

Is bremsstrahlung radiation ionizing?

Thermal bremsstrahlung is the emission given off by an ionized gas of plasma in thermal equilibrium at a particular temperature, where the distribution of electron velocities follows the well-known Maxwellian distribution.

What is the difference between bremsstrahlung and characteristic radiation?

The two unique mechanisms by which x-rays are produced are called the bremsstrahlung and characteristic processes. Bremsstrahlung x-rays produce a continuous x-ray spectrum, whereas characteristic x-rays are produced at specific narrow bands of energies.

How do I reduce bremsstrahlung?

Shielding constructed of materials of low mass number (e.g. aluminium or plastic) produce less bremsstrahlung. A shield of 10 mm-thick Perspex or 3 mm-thick aluminium provides excellent absorption for our common beta emitters.

Why is bremsstrahlung radiation called braking radiation?

It is a deflection of incident electrons by atomic nucleus, resulting in Bremsstrahlung photon emission known as “braking radiation.” Because the incident electron can be bended around the nucleus with various distances, the emitted photon has a continuous energy distribution.

What is the source of bremsstrahlung and characteristic rays?

Is created with the deceleration of electrons near the nucleus of a tungsten atom. It is non-ionizing and does not involve electrons in the orbital tungsten shells.
