GeoPIXE element maps of sample GQ1943_3


A series of element maps collected using the Maia 384 detector array on the XFM beamline at the Australian Synchrotron. Maps are both single element images and RGB composites (indicated by file name). Lower resolution versions of these files form part of a figure 1 in a paper on the application of the Maia mapping technique and are made available h... more

Maia detector element maps GeoPIXE


GQ1943_3_map_data.txt


X-ray spectra were collected using the Maia 384 detector on the XFM beamline at the Australian Synchrotron. The spectral data were collected with an incident beam energy of 18.5 keV, a pixel size of 4 ┬Ám and dwell times per pixel of 0.97 msec. The Maia XFM full spectral data were analysed using the GeoPIXE software suite which uses a fundamental parameters approach, with spectral deconvolution and imaging using the Dynamic Analysis method based on fitting a representative total spectrum, and a detailed model of Maia detector array efficiency. Spectra are fitted using a X-ray line relative intensities that reflect integration of yields and X-ray self-absorption effects for the given matrix or mineral phase and the contrasting efficiency characteristics across the detector array. The result is a matrix transformation that allows projection of the full-spectral data into element maps in this collection.


This research was undertaken on the X-ray Fluorescence Microscopy beamline at the Australian Synchrotron, Victoria, Australia. This research is supported by the Science and Industry Endowment Fund.
