In-situ Laue x-ray microdiffraction Schematic view of the in-situ micro compression setup installed at the MicroXAS beam line of the Swiss Light Source Laue diffraction is one of the oldest diffraction techniques. Traditionally, it was applied to determine the orientation of single crystals The X-ray emission from the tube is collimated at the lead glass dome to be a circular beam of 5mm diameter, see Fig 4. This primary beam diverges from the basic port to give a useful beam diameter at the crystal post of 15 mm diameter, at experimental station E.S. 13 of 20 mm diameter and at E.S. 30 of 38 mm diameter

A bent Bragg-Laue monochromator (BLM) is proposed for high-energy X-ray (∼25-60 keV) beamlines. The BLM has the unique feature of bi-directional focusing. A sagittally bent Laue crystal can focus.. The Laue camera interfaces with an X-ray tower and collimates the beam through the center of the camera toward the crystal sample. These X-rays then reflect off the sample back to the detector where the diffraction pattern is collected

Fundamental Principles of Single-crystal X-ray Diffraction Max von Laue, in 1912, discovered that crystalline substances act as three-dimensional diffraction gratings for X-ray wavelengths similar to the spacing of planes in a crystal lattice. X-ray diffraction is now a common technique for the study of crystal structures and atomic spacing A powder X-ray diffractometer consists of an X-ray source (usually an X-ray tube), a sample stage, a detector and a way to vary angle θ. The X-ray is focused on the sample at some angle θ , while the detector opposite the source reads the intensity of the X-ray it receives at 2 θ away from the source path X-RAY DETECT LAUE-HTは、USとUKの両方の主角度を測定することができます。 - US角:ガンマ、デルタ、アルファ、ベータ - UK角:ガンマ、デルタ、シータ、アルファ、カッパ、ロー、オメガ - R値結晶粒誤配向測定 XRDWIN 2.0.

An X-ray pattern obtained by this method is called a Laue pattern. Laue's theory of X-ray diffraction by crystals yields the following relations between the wavelength λ of the radiation, the parameters a, b , and c of the unit cell of the crystal, and the angles of the incident (α 0 , β 0 , γ 0 )and diffracted (α, β, γ) beams In conventional x-ray diffraction experiments on single crystals, essentially monochromatic x-rays are used. If polychromatic x-rays derived from a synchrotron radiation spectrum are used, they generate a Laue diffraction pattern.
