Portable detection device and method for determining an element in a sample using Rutherford backscattering (RBS) and particle induced X-ray emission (PIXE)

摘要

A portable detection device and method for determining atomic elements in a sample usingan alpha particle source,a first detector for measuring particle induced X-ray emission (PIXE),a second detector for measuring Rutherford Back Scattering (RBS),a first analyser, connected to said first detector, for generating a first presence signal respectively a first non detection signal of an atomic element,a second analyser, connected to said second detector, for generating a second presence signal respectively a second non detection signal of said atomic element,and a matching unit being provided for generating for each considered atomic element an acceptance signal if said matching unit received a first and a presence signal for the considered atomic element.
