A hard x‐ray micro‐nanoprobe has commenced operation at the Australian Synchrotron providing versatile x‐ray fluorescence microscopy across an incident energy range from 4 to 25 keV. Two x‐ray probes are used to collect μ‐XRF and μ‐XANES for elemental and chemical microanalysis: a Kirkpatrick‐Baez mirror microprobe for micron resolution studies and a Fresnel zone plate nanoprobe capable of 60‐nm resolution. Some unique aspects of the beamline design and operation are discussed. An advanced energy dispersive x‐ray fluorescence detection scheme named Maia has been developed for the beamline, which enables ultrafast x‐ray fluorescence microscopy.
