Micro-computed tomography beamline of the Australian synchrotron: Density measurements

The Micro-Computed Tomography (MCT) beamline at the Australian Synchrotron (ANSTO) offers superior capabilities in micrometer-scale spatial resolution and three-dimensional x-ray imaging. MCT is the first of the eight new BRIGHT beamlines and has been operating successfully with users for approximately two years. It is a bending magnet beamline capable of delivering a white beam, a pink beam, or a monochromatic beam in the 8-40 keV energy range using a Double Multilayer Monochromator (DMM). Ongoing development continues at the MCT beamline to extend its capabilities. In this article, we present the operation and energy calibration of the DMM, highlighting the unique advantages offered by synchrotron-based micro-CT and its application for quantitative imaging, such as density measurements using monochromatic energy.
