X-Ray CTX - HWU-RCCS (UK4.2)

Introduction:

X-ray computerised tomography (CT) is a non-destructive analytical technique used in engineering, science and medicine to visualise the internal structure of machine parts, computer components, man-made and natural materials. The CT Scanner analysis software can output a variety of files for further analysis, reprocessing and presentation, e.g. 2D x-ray images, 3D volume files, image slices, model animation and movies, as well as performing some advanced calculation techniques, e.g. defect analysis (porosity or inclusion), and flow and diffusion analysis (transport phenomena). This newly installed instrument is now fully operational offering imaging analysis across a broad range of research fields.

Specifications:

The Research Centre for Carbon Solutions (RCCS) at Heriot-Watt University, is an interdisciplinary world-leading engineering centre, inspiring and delivering innovation for the wider deployment of technologies needed to meet necessary carbon targets. The RCCS occupy over 350 m², across ten separate and interlinked laboratories, with dedicated high-end analytical research instruments and many bespoke in-house designed systems and rigs for advanced research and process development dedicated to research into Carbon Capture, Storage, Transport and Utilisation, in addition to facilitating several projects in the fields of Low Carbon System and Negative Emission Technologies. Along with facilitating our core research activities, the RCCS welcomes Academic and Industrial collaborators, and offers external contract analysis services.

Non-destructive imaging technique providing valuable information about the internal structure of an array of materials is accomplished using a Nikon XT H 225 CT Scanner is fitted with a 225kV x-ray gun, a 5-axis manipulator sample stage, and a 14-bit 3140x2360 pixel detector. The micro-focus x-ray gun has a multi-metal target and numerous filtration options, which allows the production of hard and soft x-rays, hence increasing the type of samples that can be analysed. The 5-axis manipulator stage allows for precise control of the sample during analysis in either circular or helical mode, and has a maximum sample weight limit of 15kg. The detector panel has a pixel size of 127µm, and can collect 65536 shades of grey, at up to 3 frames per second. The ultimate resolution of the system is dependent on numerous factors, including but not limited to, magnification and rotation intervals, but is typically in the range of 10-100µm.
