... • There are different types – Ion Microprobe, TOF-SIMS, and Quadrupole SIMS. The first two are more important: the first is also called dynamic SIMS where a complete depth profile can be done and uses q/m ratio to separate ions, and the 2nd used for static SIMS as only a few monolayers are removed, ...

Rutherford backscattering spectrometry
Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science. Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.
