Abstract
A new method for 3D hydrogen profiling is introduced. The method is ba sed on the proton-proton coincidence measurement and uses a standard m icrobeam facility. The 3D profile is derived from depth profiles at a set of points combined with the average hydrogen areal density of the sample. The deconvolution technique, in which the depth profiles are d escribed as a sum of cubic splines, is applied. The average hydrogen a real density is determined by a scanning proton microbeam. Samples of a known hydrogen distribution were used to test the method.
