The principle of the analysis is to observe the radiation X emitted during the interaction of the bundle of incidental particles with the atoms of the target to be studied. We use a bundle of protons of equal energy in 3MeV forming on the target a circular spotlight of 1mm of diameter and a current incident of the order of 1,5 nA. In our experimental configuration, the object is arranged at 1cm of the Kapton's nose of exit, and two X detectors placed in 135 ° forward to the surface of the sample, on both sides the axis of the bundle. These Analyses are realized in association with the cell of transfer MYSTERY (CENBG-Gradignan). Detailed view of the PIXE system used.
Particul Iduced X-ray Emission ANALYSE
The technique PIXE ( Particle Induced X-Ray Emission) in extracted bundle is a not destructive analysis, which allows to determine the elementary composition (qualitative and semi-quantitative) major, minor and trace elements.
