3D hydrogen profiling using a proton microbeam

A new method for 3D hydrogen profiling is introduced. The method is based on the proton-proton coincidence measurement and uses a standard microbeam 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 described as a sum of cubic splines, is applied. The average hydrogen areal density is determined by a scanning proton microbeam. Samples of a known hydrogen distribution were used to test the method.
