When switching the X-ray apparatus on, check whether the ventilator in the tube chamber starts rotating.Protect the X-ray apparatus against access by unauthorized persons.Īvoid overheating of the anode in the X-ray tube.Before putting the X-ray apparatus into operation, inspect it for damage and check whether the voltage is switched off when the sliding doors are opened (See instruction sheet of the X-ray apparatus).The built-in protective and shielding fixtures reduce the dose rate outside the X-ray apparatus to less than 1 µSv/h, which is of the order of magnitude of the natural background radiation. The X-ray apparatus fulfils all regulations on the design of an X-ray apparatus and fully protected device for instructional use and is type approved for school use in Germany (BfS 05/07 V/Sch RöV or NW 807 / 97 Rö).

The key difference between Bragg and Laue diffraction is that Bragg diffraction gives the angles for coherent and incoherent scattering from a crystal lattice whereas Laue diffraction relates to the scattering of waves in the process of diffraction by a crystal. Lau diffraction doesn’t require the radiation to be reflected specularly.īragg and Laue diffractions are used as crystallographic techniques and laws to describe different crystal systems. Laue diffraction doesn’t require particular planes or spacing.īragg diffraction requires specular reflection of the incident radiation. Laue diffraction relates to the scattering of waves in the process of diffraction by a crystal.īragg diffraction requires lattices that are grouped into different families of planes. 2d sinθ gives the path difference between two waves that undergo constructive interference.īragg diffraction gives the angles for coherent and incoherent scattering from a crystal lattice. Lambda (λ) is also a variable, and it is the wavelength of the incident X ray beam. It is also called lattice spacing and is a variable parameter (varies based on the type of crystal). Here, d is the distance between atomic layers of the crystal lattice. The angle observed here is known as theta (θ). When X rays are scattered from a crystal lattice, the Bragg’s law describes the angles at which the X ray beams are reflected by cleavage faces of the crystal. Crystallographic techniques include incidence of X rays on crystal lattices and observing wave scattering. Side by Side Comparison – Bragg vs Laue Diffraction in Tabular Formīragg diffraction gives the angles for coherent and incoherent scattering from a crystal lattice. Bragg’s law, on the other hand, gives the angles for coherent and incoherent scattering from a crystal lattice. The Laue equation was named after Max Von Laue (1879-1960). Laue diffraction (or Laue equation) relates to the scattering of waves in the process of diffraction by a crystal. ![]() Bragg’s law is a special case of Laue diffraction. ![]() Key Difference – Bragg vs Laue Diffractionīragg and Laue diffractions are laws used to explain X-ray diffractions in crystallographic techniques.
