The digital imaging hub is based within the Institute of GeoEnergy Engineering. It comprises the Centre for Environmental Scanning Electron Microscopy (CESEM), opened in 1998, that includes a suite of scanning electron microscopes (SEM), and image processing / manipulation PC / workstation facilities. The digital imaging hub now (October 2019) also incorporates X-ray tomography (XRT), with an RX solutions Easy Tom 150 (known as ET), within the Geomechanics group facilities. Additional optical microscopes are currently available within the Lyell Centre and through the British Geological Survey (BGS), a second XRT facility at the School of Engineering and Physical Sciences (EPS), a dual beam SEM within EPS, and super resolution optical microscopes at IB3.
SEM facilities include energy dispersive x-ray (EDX) analysis, an electron backscattered diffraction detector (EBSD), and cathololuminescence (CL) imaging. In addition samples can be wetted for wettability studies, manipulated using a pair of tensile-compression stages, and heated to 1000°C.
