IBA uses MeV ion beams to probe the composition and obtain elemental depth profiles in the near-surface layer of solids.
This technique enables:
- The analysis of the biodistribution and biopersistence (in vivo) of nanomaterials, their characterization and quantification;
- The characterization of thin-film materials and airborne particles;
- The study of phase transformation.
For decades, the IBA has played a leading role in nuclear astrophysics, materials science, life sciences, heritage sciences, and archaeology.
Tandetron Linear Accelerator (ALTAÏS)
Capable of generating ion beams composed of any stable element with energies up to 16 Mega electron volts (MeV), the particle accelerator enables the analysis (IBA) and modification (IBMM) of thin layers of numerous materials.
