Type and energy of particles: protons or deuterons from 1 to 4MeV or Alphas from 2 to 6MeV for Alphas. Beam size: down to 20µm. Single spot or mapping on areas up to cm²-sized area (max 20x20cm²). PIGE system: HPGe detector. Limits of detection : down to 100ppm regarding the elements
PIGE allows to get composition of materials down to traces elements (ppm) on light elements not detected by PIXE (Li, B, F, ...). Elemental composition will help to identify pigments, manufacturing techniques, provenance. PIGE can also be used to check soda glass degradation.
