Accelerator Mass Spectrometry at the 1 MV Tandetron

Welcome to RoAMS

Accelerator Mass Spectrometry (AMS)

AMS is today’s most sensitive isotopic analysis method. Using a particle accelerator, usually a Tandem type, the AMS spectrometer measures one by one the ions of the investigated species.

Measurement sensitivity can reach down to 10 -15 rare isotope / abundant isotope, in other words, AMS allows the determination of the existence of a single atom in torrent of one million billion other foreign atoms.

Due to its exceptional sensitivity, this method has opened a very wide range of applications in various fields:

medicine, archeology, paleogeomorfology, geology, atmospheric physics, paleoclimatology, astrophysics, nuclear physics, nuclear pollution tracking, etc.
