Preliminary results on multiple angular detection Auger spectroscopy

From elementary calculations of the Auger signal intensities from a specimen at two different take-off angles, O 1 and O 2 , it is shown that the simultaneous acquisition of these spectra allows homogeneous alloys ans stratified samples to be identified and also the presence of topographic effects. The preliminary results confirm the potential of multiple angular detection Auger electron spectroscopy (MADAES) that can be developed by using only one analyser of cylindrical mirror type. Further developments are also indicated
