The University of Manchester at Harwell

Equipment

We operate and maintain several pieces of equipment that are used for in situ experiments on beamlines or that can be used for off-line measurements complementing X-ray or neutron experiments. When The University of Manchester equipment is used in an experiment that results in a publication, the publication will reference The University of Manchester collaboration in the following manner: "This experiment was possible due to the contribution of The University of Manchester at Harwell (UoMaH) rig reference rig name".

Nikon CT 225ST – X-ray computed tomography system

Our Nikon XTEK XTH 225 micro-focus CT system captures the internal geometry and morphology of a wide range of materials.

Applications:

  • Advance material research (porosity, distribution of specimens, real-time radiography of structural modification etc.)
  • Fault detection
  • Digital archiving of models
  • Assembly inspection of complex mechanism or parts
  • Part to CAD comparison
  • Analysis of biological structures (medical or palaeontological samples)
  • Non-destructive technique to study hidden features of historical and archaeological samples.

 Benefits: 

  • Suitable for a wide range of materials and sample sizes
  • Flexibility combined in a single system: X-ray for quick visual inspection, CT for in-depth analysis
  • Fast data capture and high-quality images
  • Fast operation with interactive joystick navigation
  • High-resolution digital imaging and processing
  • Safe system
  • Tight integration with industry standard post-processing applications
  • Can be used in conjunction with a variety of rigs for mechanical testing (i.e. tension, compression, indentation etc.).

Features:

  • Powerful 225 kV micro-focus source with a 3 µm spot size
  • W reflection target and an optional multi-metal reflection target (W, Cu, Mo, Si).
  • 5-axis fully programmable part manipulator  X(450 nm), Y(350 nm), Z (725 nm), Tilt (+/- 30o), Rotation (330o)
  • Real-time X-ray visualization and fast CT reconstruction
  • Inspection cabinet (2.4 m x 1.3 m x 2.2 m) can accommodate samples up to 50 kg and 50 cm diameter in addition to rigs.
  • Option to image sub-volumes (region of interest) within larger specimens (not available for all samples)
  • System to allow routing of cables and pipes that can control and feed in situ rigs for time-resolved (4D) µ-CT experiments.
  • 16 bit flat panel detector with 2000 x 2000 active pixels and 200 µm pixel size
  • Inspect-X software
  • Scan times vary from 30 minutes to several hours
  • Resolution will vary from three to hundreds of microns, depending the size of the samples.

Data analysis will be performed either in house or by 3Dmagination.
