Having described the basic mode of operation of the Itrax core-scanner countless times in the past few months, I thought it time for a proper poster with nice diagrams, so I recently made this poster for the Itrax facility I’m looking after. It has a description of how x-ray beams are created and controlled in the scanner, the principles of measurement, and an explanation of how deriving chemical compositional data from fluorescence spectra can be done. It’s available from the resources page of this website. Let me know if you print one and use it – I love seeing photos of resources I’ve created being used!
If you need more information on the Itrax core scanner, there’s this paper and this edited volume that may be of interest.
