Schematic of the X-ray fluorescence microprobe instrument at the Australian Synchrotron XFM beamline (Paterson et al., 2011). A monochromated X-ray beam is focused to a small spot using a Kirkpatrick–Baez (K–B) mirror pair. The sample is scanned and rotated through this focus. A segmented transmission detector records the transmitted intensity and position to obtain differential phase contrast images (de Jonge et al., 2008), and the energy-resolving Maia detector system (Kirkham et al., 2010) records an event stream including X-ray energy and specimen position information. |
