Abstract
The Micro-Computed Tomography (MCT) beamline is one of the first new beamlines to be constructed at the Australian Synchrotron as part of the BRIGHT program. MCT complements the X-ray imaging/tomography capability provided by the Imaging & Medical Beamline (IMBL), and targets applications requiring higher (sub-micron) spatial resolution and involving commensurately smaller samples. MCT is a bending-magnet beamline, operating in the 8 to 40 keV range, based on a novel double-multilayer monochromator. Filtered white and pink beams are also available, the latter utilising a single-bounce mirror. MCT will benefit from X-ray phase-contrast modalities (such as propagation-based, grating-based and speckle) in addition to conventional absorption contrast, and is equipped with a robotic stage for rapid sample exchange. A higher-resolution CT configuration based on the use of a Fresnel zone plate system will also be available soon. Anticipated application areas for non-destructive 3D sample characterisation include biomedical/ health science, food, materials science, and palaeontology. This presentation will provide a description of the commissioning activities undertaken thus far, leading to the first user operations taking place in the current cycle (2022/3). Future developments on the beamline will also be discussed.
