7 January 2002 New results in x-ray computed fluorescence tomography
Author Affiliations +
We present recent results of fluorescence tomography experiments obtained on a variety of samples originating from the fields of Mineralogy, Space Sciences or Botany. The ID22 hard X-ray microanalysis beamline of the ESRF was used in scanning beam mode to record fluorescence spectra in pencil-beam collection mode for energies of 14 to 22.5 keV and micron-sized beamspots. Trace element concentrations of a few hundred ppm were successfully imaged in inhomogenous samples of less than 500 microns and resolutions up to 2 microns.
