| Abstract: | A hard x-ray micro-nanoprobe is being constructed at the Australian Synchrotron [1]
to provide sub-micron spatial resolution across an energy range of 4.5–25 keV. The
SXM will combine 2D mapping with μ-XRF, μ-XANES and μ-XAFS for elemental and
chemical microanalysis. The primary design goal is to achieve sub-100 nm spatial
resolution with DE/E ~10-4, and sub-ppm elemental sensitivity. The optical design is
a novel “all horizontal” scheme [2]. Interchangeable Fresnel zone plates and
Kirkpatrick-Baez mirrors will be used. An advanced fluorescence detector developed
by BNL [3] and CSIRO [4] featuring a large solid-angle planar silicon array will enable
count rates up to 108 events/sec and real-time processing with deconvoluted image
projection. A differential phase contrast detection scheme [5] will be employed for
quantitative measurement of soft matter [6].
The Microspectroscopy Beamline will commence operation in late 2008 and will accommodate a diverse range of environmental, biological and materials science applications to cater for the broad requirements of the Australian community. The design, anticipated performance and research applications will be discussed. |
