Abstract

We recorded a series of spectral maps of a hematite particle by combining a scanning proton microbeam excitation with detection of X-rays by a Si(Li) spectrometer equipped with polycapillary lens. The particle was driven through the sensitive microvolume to allow for a reconstruction of concentration in three dimensions. Beside the description of the experiment, important aspects of data analysis are emphasized to show the potential of the confocal micro-PIXE (Proton Induced X-ray Emission) imaging method: at present, this is limited by the focusing properties of the polycapillary lens.
