Surface layer destruction during ion beam analysis
In ion beam analysis the decrease of the measuring signal with a number of incident ions, due to a destruction of the surface layer being analyzed, depends critically on the lateral intensity distribution in the analyzing ion beam. For the assumption of destruction in one step, the decrease was calculated and the obtained analytical formulae was fitted to the decrease as measured in ERDA and PIXE analyses. This allows to obtain values for the destruction cross sections for the ions and the samples in the analysis, as well as information about the lateral intensity distribution in the analyzing ion beam.
