- Overview: The x-ray diffraction facility is a part of the Bragg Centre for Materials Research.
Located in the fittingly named Bragg Building, after Sir William Henry Bragg and Lawrence Bragg who won the 1915 Nobel Prize for ‘their services in the analysis of crystal structure by means of X-rays’ whilst Sir William Henry Bragg was a Professor at Leeds between 1909-1915.

Just as it was the ambition of the Braggs’; accessing, understanding and unlocking atomic structure is the still the aim of our x-ray diffraction facility, over 100 years on.
This allows us to better understand and exploit materials and devices to their full potential. To achieve this, the facility houses a range of x-ray diffractometers as well as a suite of analysis tools to structurally characterise powders, thin films and coating, solid materials, single crystals and devices.
Our aim is to produce world-class structural analysis on a wide range of materials to improve the understanding of a materials physical and chemical behaviour such as electrical, thermal, magnetic and mechanical properties. By determining the spacing between crystal lattice planes and the length scales over which they persist, we are able to determine the 3D atomic structure of materials.
We have several x-ray diffractometers which can be operated in many different modes. All modes reveal different information about the material such as:
- Residual stress analysis - Determine residual stress within the structure to better understand the physical properties
- Texture (preferred orientation) analysis - Study preferential ordering and epitaxial growth of crystallites (such as thin films or single crystals)
- Bragg-Brentano - Phase identification in crystalline and non-crystalline materials as well as quantification of phases within mixtures
- Line broadening - Determination of crystallite size
- Hot and cold stage analysis - To study the effect of different temperatures on the structure and crystalline nature of a material
- Reflectometry – To characterise surfaces, thin films and multilayers
